Every year, property owners, park managers, and public land agencies across North America watch helplessly as rain transforms hillsides into muddy disaster zones. The U.S. Geological Survey estimates that landslides and erosion cause over $3 billion in property damage annually in the United States alone. In California, the crisis intensifies each year as wildfires strip vegetation from millions of acres, leaving slopes dangerously vulnerable to debris flows when winter rains arrive.
Traditional erosion control methods—silt fences, erosion blankets, riprap—often fail on slopes steeper than 2:1 because they don’t address the fundamental problem: loose soil has nothing anchoring it in place. This challenge multiplies on public lands, state parks, and wildfire-scarred terrain where crews must stabilize vast acreage before the next storm system arrives.
This guide explains how geocell technology solves hill erosion control challenges that defeat conventional approaches. You’ll learn why slopes fail, how cellular confinement systems prevent soil movement, and what specifications ensure long-term stabilization—whether you’re protecting a residential hillside, restoring a fire-damaged state park, or stabilizing highway embankments before atmospheric river season.
Why Hills Erode: Understanding the Problem Before Choosing Solutions
Before selecting any erosion control method, you need to understand what’s actually happening on your slope. Hill erosion isn’t random—it follows predictable patterns driven by specific forces. Recognizing these patterns helps you choose solutions that address root causes rather than symptoms.
The Physics of Slope Failure
Water is the primary driver of hill erosion. When rain falls on a slope, several destructive processes begin simultaneously. Sheet erosion removes thin layers of topsoil uniformly across the slope surface. This happens when rainfall intensity exceeds the soil’s infiltration capacity, creating shallow overland flow that carries loose particles downhill.
Rill erosion creates small channels as concentrated water flow cuts into the soil. These channels deepen with each rain event, eventually becoming gullies that can be several feet deep. Once gullies form, they accelerate erosion by concentrating even more water flow.
Gravity constantly pulls soil particles downslope. On steep grades, this gravitational force overcomes the friction holding soil in place. Saturated soil is particularly vulnerable because water between soil particles reduces friction, essentially lubricating the slope for failure.
Vegetation roots normally anchor soil against these forces. But on steep slopes, disturbed sites, or areas with poor soil, vegetation struggles to establish before erosion removes the topsoil it needs. This creates a vicious cycle: erosion prevents vegetation, and lack of vegetation accelerates erosion.
The Post-Wildfire Erosion Crisis
Nowhere is this cycle more devastating than on wildfire-burned slopes. California’s fire seasons now regularly consume over a million acres annually, with the 2020 fire season alone burning more than 4.2 million acres according to CAL FIRE records. Each burned acre becomes an erosion emergency.
Wildfires don’t just remove vegetation—they fundamentally alter soil properties. Intense heat creates a hydrophobic (water-repellent) layer in the upper soil that prevents water infiltration. Rain that would normally soak into vegetated slopes instead runs off burned areas at rates up to 10 times higher than pre-fire conditions.
The burned slopes then face California’s atmospheric rivers—concentrated corridors of water vapor that deliver intense precipitation over short periods. When these systems arrive over fire-scarred terrain, the results are catastrophic. The January 2018 Montecito debris flows killed 23 people when rain fell on slopes burned by the Thomas Fire just weeks earlier. Similar events have struck communities across Southern California repeatedly.
Public land managers face impossible timelines. The window between fire containment and winter rains often spans just 8-12 weeks. Traditional revegetation efforts can’t establish protective vegetation that quickly. Many burned slopes remain vulnerable for two to five years after fire as vegetation slowly recovers.
Why Traditional Erosion Control Methods Fail
Property owners and land managers typically try several approaches before discovering geocells. Understanding why these methods fail—especially under extreme conditions—explains what makes cellular confinement different.
Erosion control blankets and mats work well on gentle slopes under 3:1 (33%) grade with normal rain patterns. They hold seeds in place while vegetation establishes and reduce the velocity of sheet flow. But on steeper slopes or during intense rain events, water flows underneath these blankets, lifting them away from the soil surface. The blankets become obstacles that concentrate water flow rather than dissipating it. On post-fire hydrophobic soils, blankets provide almost no benefit because water runs across the surface regardless of covering.
Riprap and rock armor provide excellent protection against water scour but don’t support vegetation. On long slopes, riprap sections often experience undercutting at the toe or settlement as smaller particles wash out from between rocks. Riprap also creates aesthetically harsh surfaces inappropriate for residential properties, public parks, or recreational areas where appearance and ecological function matter.
Straw wattles and fiber rolls are commonly deployed on burned slopes as emergency measures. California’s emergency watershed protection programs have installed millions of feet of these products after major fires. While they slow sheet flow on moderate slopes, they provide minimal protection against the concentrated flows and debris movement that occur during atmospheric river events. Studies of post-fire installations frequently document wattle failure rates exceeding 50% after significant rain events.
Hydroseeding and erosion control seeding establish vegetation quickly on moderate slopes but struggle on grades steeper than 2:1. On burned slopes with hydrophobic soils, seeds wash away before germination even on gentler grades. The hydrophobic layer can persist for years, preventing the root establishment that seeded vegetation requires.
Identifying Your Slope Erosion Type
Walk your slope and identify which erosion patterns are present. This assessment guides your stabilization approach.
Sheet erosion appears as uniform soil loss across the slope face. You’ll notice exposed roots, pedestals of soil around rocks or vegetation, and gradual lowering of the soil surface. Sheet erosion indicates the entire slope surface needs protection.
Rill and gully erosion creates visible channels running downslope. Measure the depth and spacing of these channels. Rills under 1 inch deep can often be addressed with surface treatments. Gullies over 6 inches deep require more aggressive intervention including possible regrading before stabilization.
Mass movement includes slumps, slides, and creep where entire sections of soil move as a unit. Signs include curved tension cracks at the top of slopes, bulging at the toe, and tilted trees or fence posts. Mass movement indicates deeper instability that may require engineering analysis beyond surface erosion control.
Concentrated flow erosion occurs where water from upslope areas (roof drains, parking lots, culverts, trail drainage) discharges onto the slope. These areas experience severe localized erosion even on otherwise stable slopes. On public lands, trail intersections and road drainage outlets commonly create these concentrated flow problems.
Post-fire erosion combines multiple mechanisms. The hydrophobic soil layer increases runoff volume. Loss of vegetation and organic debris eliminates surface roughness that slows flow. Burned root systems no longer anchor soil. And sediment mobilization from upslope areas adds debris load to flowing water. Effective post-fire stabilization must address all these factors simultaneously.
How Geocells Solve Hill Erosion Control Challenges
Geocell technology approaches erosion control fundamentally differently than surface treatments or rigid structures. Instead of covering the slope surface or fighting gravitational forces with massive weight, geocells create a three-dimensional soil confinement system that works with natural processes while preventing soil movement.
The Cellular Confinement Principle
Geocells are three-dimensional honeycomb structures made from high-density polyethylene (HDPE). When expanded and placed on a slope, they create thousands of individual cells that confine soil, aggregate, or vegetation growth media within defined compartments.
This cellular confinement prevents the lateral movement of infill material under gravitational stress. Each cell wall supports adjacent cells, distributing forces across the entire system rather than allowing localized failures to cascade. The interconnected structure functions as a flexible mattress that conforms to slope contours while maintaining structural integrity.
Think of it this way: loose soil on a slope is like marbles on a tilted board—gravity pulls everything downward with nothing to stop the movement. Geocells create compartments like an egg carton. The marbles (soil particles) stay in their individual compartments even when the board tilts. The compartment walls prevent lateral movement while allowing the system to flex with ground movement.
How Geocells Address Each Erosion Mechanism
Cellular confinement directly counters each erosion mechanism through specific properties.
Against sheet erosion, the cell walls interrupt overland water flow, breaking it into slower-moving segments that can infiltrate into the soil rather than running off. Perforated cell walls (standard on BaseCore geocells) allow lateral water movement between cells while maintaining soil confinement. This prevents the concentrated flow channels that cause rill formation.
Against rill and gully erosion, the cell structure prevents water from cutting channels into the confined soil. Even if water concentrates, it flows over the top of cells without eroding the soil within them. Existing rills and shallow gullies can be filled during installation, with the geocell system preventing their reformation.
Against gravitational creep and sliding, the interconnected cell structure anchors soil in place. Each cell’s contents are supported by adjacent cells, creating a continuous reinforced mass that resists downslope movement. Staking the system into stable subgrade transfers gravitational forces into the underlying slope rather than allowing surface material to slide.
Against post-fire hydrophobic conditions, geocells work differently than they do on normal soils. The cell structure holds topsoil or growth media in place even when underlying native soil repels water. Vegetation establishes in the confined growing media above the hydrophobic layer. As roots grow and the hydrophobic layer naturally breaks down over 2-5 years, the vegetation is already established and continues protecting the slope.
Supporting Vegetation Establishment on Challenging Slopes
For long-term hill erosion control, vegetation provides the ultimate protection. Root systems anchor soil far deeper than any surface treatment. Vegetation canopy intercepts rainfall, reducing impact energy. Organic matter improves soil structure and infiltration capacity over time.
Geocells create conditions that allow vegetation to establish on slopes where it otherwise couldn’t survive. The cells hold seeds and growth media in place during germination and early growth when plants are most vulnerable. Perforated cell walls allow roots to spread between cells, eventually creating a continuous root mass throughout the geocell system.
BaseCore geocells are available in black (standard), beige, and green. For vegetated slope applications, the green option helps the installation blend with surrounding landscapes during the establishment period before vegetation fully covers the cells. This matters particularly for parks, residential areas, and public spaces where aesthetics during the establishment period affect community acceptance.
On public lands and parks, the vegetation choices can support native species restoration goals. The geocell structure provides the stable growing environment needed for native grasses, wildflowers, and even shrubs to establish on slopes that would otherwise erode before natives could take hold. This allows land managers to meet both erosion control and ecological restoration objectives simultaneously.
Applications Across Property Types and Land Uses
Hill erosion control needs vary dramatically depending on the setting. A residential hillside has different requirements than a highway embankment or a state park trail system. Understanding application-specific considerations helps you specify the right solution.
Residential and Commercial Properties
Private property owners typically face hill erosion on building site slopes, drainage channels, pond embankments, and property boundary grades. The challenges include aesthetic requirements (neighbors and HOAs care about appearance), limited access for large equipment, budget constraints, and often steep slopes created during construction grading.
BaseCore systems address these challenges through relatively simple installation that doesn’t require specialized equipment, vegetation support that creates natural appearance after establishment, flexibility in cell depth selection (2-inch through 8-inch options) to match slope severity and soil conditions, and proven longevity that justifies the investment over repeated repairs.
For residential applications, 3-4 inch cell depths typically provide adequate erosion control on slopes up to 2:1 with vegetated infill. Steeper slopes or areas with concentrated water flow may require 6-inch cells for additional confinement strength.
Highway and Transportation Infrastructure
Departments of transportation manage thousands of miles of roadway embankments, cut slopes, and drainage channels. These slopes experience constant assault from road runoff, often concentrated at culvert outlets and ditch intersections. Maintenance budgets strain under repeated erosion repairs on the same slopes.
Geocell systems provide long-term solutions that reduce ongoing maintenance costs. Unlike riprap that settles and requires periodic resetting, or erosion blankets that degrade and must be replaced, properly installed geocell systems maintain their structural integrity for decades. The Federal Highway Administration has documented geocell applications for slope stabilization dating back to the 1980s.
Transportation applications often require heavier specifications. Six to eight-inch cell depths handle the concentrated flows from road drainage. Aggregate infill rather than vegetated topsoil provides maximum scour resistance at high-velocity discharge points. Where vegetation is desired on slopes adjacent to drainage structures, combination systems use aggregate-filled cells in high-scour zones transitioning to vegetated cells on general slope areas.
Public Lands, Parks, and Recreation Areas
Public land managers face unique erosion control challenges that make geocell systems particularly valuable. Trails concentrate foot traffic and water flow, creating erosion that spreads into surrounding areas. Campground sites, parking areas, and day-use facilities require erosion control that remains safe for public use and visually appropriate for natural settings.
National forests, state parks, and municipal open spaces often manage hundreds of miles of trails across varied terrain. Trail erosion control traditionally relied on water bars, check dams, and periodic regrading. These approaches require frequent maintenance and often redirect erosion rather than preventing it. Geocell systems can stabilize trail surfaces and adjacent slopes with minimal ongoing maintenance, allowing trail crews to focus on other needs.
The recreation context also emphasizes vegetation establishment. Visitors expect natural-appearing landscapes, not industrial erosion control structures. Geocell systems with vegetated infill meet this expectation while providing superior erosion protection. Within one to two growing seasons, established vegetation largely conceals the geocell structure while roots create permanent soil anchoring.
Interpretive opportunities exist as well. Some parks have incorporated geocell erosion control projects into environmental education programming, demonstrating how engineering solutions can work with natural processes to restore damaged landscapes.
Post-Wildfire Emergency Stabilization
After major wildfires, land managers race against time to stabilize burned slopes before winter rains trigger debris flows. The Burned Area Emergency Response (BAER) program and similar state-level programs assess fire damage and implement emergency watershed treatments each fire season.
Geocell systems offer significant advantages for post-fire stabilization. Installation proceeds quickly—an experienced crew of four can install approximately 10,000 square feet of BaseCore panels per day on prepared slopes. This speed matters when crews are working against weather windows measured in weeks.
The system works on hydrophobic soils where other treatments fail. Geocells hold imported topsoil or growth media above the water-repellent layer, allowing vegetation to establish while the hydrophobic condition naturally degrades over time. Traditional seeding on hydrophobic slopes simply washes away.
Geocells also address the debris flow risk that makes post-fire erosion so dangerous. The cellular structure captures and holds sediment that would otherwise mobilize during rain events. While geocells alone cannot stop large debris flows originating far upslope, they can stabilize the immediate slopes below communities, roads, and infrastructure that would otherwise contribute additional material to debris flows or suffer direct erosion damage.
California’s recurring fire-rain cycles make permanent stabilization solutions more economical than repeated temporary treatments. Slopes treated with straw wattles after one fire often require the same treatment again after the next fire burns through the recovering vegetation. Geocell installations provide permanent infrastructure that survives subsequent fires (the HDPE material does burn, but the established root systems and soil structure improvements persist) and accelerates post-fire recovery.
Channels, Swales, and Concentrated Flow Areas
Not all erosion control applications involve slope faces. Drainage channels, roadside swales, detention basin slopes, and other concentrated flow areas experience severe scour during storm events. These linear features often run for thousands of feet, making traditional armoring approaches expensive.
Geocell systems provide flexible channel lining that conforms to varying cross-sections while preventing scour. Aggregate-filled cells handle high-velocity flows without displacement. Vegetated cells work in lower-velocity applications where aesthetics matter, such as park drainage swales or residential detention basins.
The permeability of geocell channel linings offers advantages over concrete or other impervious linings. Water infiltrates through the system, reducing downstream peak flows and supporting groundwater recharge. This characteristic helps projects meet stormwater management requirements that increasingly emphasize infiltration over conveyance.
Specifications and Selection for Slope Applications
Selecting the right geocell specifications ensures your erosion control system performs as needed. Different slope conditions require different configurations. Understanding the variables helps you work with your BaseCore representative to specify appropriately.
Cell Depth Selection for Slopes
Cell depth is the primary specification affecting erosion control performance. BaseCore manufactures geocells in depths from 2 inches through 8 inches, with custom depths available for specific requirements.
Light-duty slope applications on grades up to 3:1 (33%) with vegetated infill and no concentrated flow typically perform well with 2-3 inch cell depths. These shallow depths minimize material costs and reduce infill quantities while providing adequate confinement for topsoil and vegetation establishment.
Standard slope applications on grades from 3:1 to 2:1 (33-50%) or gentler slopes with moderate concentrated flow generally require 4-inch cell depths. This provides sufficient wall height to confine soil during intense rain events while remaining economical for larger installations.
Heavy-duty slope applications on grades steeper than 2:1, slopes with significant concentrated flow, or post-fire installations on hydrophobic soils typically require 6-inch cell depths. The additional confinement handles greater gravitational forces and higher-velocity water flow.
Severe applications including channel linings, scour-prone culvert outlets, and slopes approaching 1:1 (45 degrees) may require 8-inch cell depths or specialized engineering analysis. These applications often use aggregate infill rather than vegetated topsoil for maximum erosion resistance.
Panel Sizing for Slope Projects
BaseCore manufactures panels in standard sizes including 10×12, 10×20, and 9×18 feet, with custom sizing available to minimize waste on specific projects. For slope applications, consider panel layout carefully.
Larger panels reduce connection points but may be more difficult to handle on steep slopes. Smaller panels allow easier maneuvering on challenging terrain. Your BaseCore representative can recommend panel sizing that balances installation efficiency with jobsite practicality.
For large slope projects common on public lands or transportation applications, custom panel sizing that matches your slope dimensions can significantly reduce cutting waste. When ordering for a 200-foot-wide slope face, for example, panel widths that divide evenly into 200 feet eliminate the partial panels and cutting labor at edges.
Infill Material Options
The material filling geocells determines both erosion protection performance and surface characteristics.
Topsoil infill supports vegetation establishment and creates natural appearance after grass or other plants mature. For vegetated slopes, use quality topsoil appropriate for your climate and intended vegetation. The geocell cells should be filled completely, slightly overfilled before settlement, to provide consistent growing media depth throughout the installation.
Aggregate infill provides maximum scour resistance for channels, concentrated flow areas, and high-velocity applications. Use angular crushed stone—never round river rock that can roll within cells. The standard specification of #57 stone with 15-20% fines works well for most slope applications. The fines help lock the aggregate matrix together within cells.
Combination approaches use aggregate in high-scour zones (channel bottoms, culvert aprons, concentrated flow paths) transitioning to vegetated topsoil on adjacent slope areas. This provides maximum protection where needed while maintaining natural appearance elsewhere.
Soil-aggregate blends work for applications requiring both vegetation and significant erosion resistance. A mixture of topsoil and angular aggregate allows grass establishment while the aggregate provides matrix stability. This approach suits moderate slopes with occasional concentrated flow.
Anchoring Requirements on Slopes
Unlike level parking applications where infill weight alone holds panels in position, slope installations require positive anchoring to the underlying subgrade. Staking prevents the geocell system from creeping downslope under gravitational forces before and during vegetation establishment.
Use 1/2-inch rebar stakes for most slope applications. Stake length depends on slope grade and soil conditions. Level to 3:1 slopes need 12-18 inch stakes. Slopes from 3:1 to 2:1 need 18-24 inch stakes. Slopes steeper than 2:1 may require 24-36 inch stakes or engineered anchoring systems.
Drive stakes through cell walls at connection points between panels and at intermediate points across panel faces. Typical spacing runs 4-6 feet both directions on moderate slopes, decreasing to 2-4 feet on steeper grades. Stakes should penetrate below the cell bottom into stable subgrade, with tops below the infill surface to avoid interfering with vegetation establishment or creating hazards.
Extremely steep slopes or unstable soil conditions may require deadman anchors, helical anchors, or other engineered anchoring systems. Your BaseCore representative can discuss options for challenging applications.
Geotextile Integration
A geotextile fabric layer between the subgrade and geocell system prevents fine soil particles from migrating upward into the infill material. This separation maintains infill performance and prevents voids from developing as fines wash out.
For slope erosion control, specify 6-12 oz non-woven geotextile fabric depending on soil conditions. Lighter fabric (6-8 oz) suits stable soils with low silt content. Heavier fabric (10-12 oz) provides better separation on fine-grained or silty soils prone to pumping.
Install geotextile across the prepared slope surface with minimum 12-inch overlaps at seams. Pin fabric temporarily to prevent movement during geocell installation. The fabric can extend beyond geocell boundaries to provide transition zones where the stabilized area meets adjacent surfaces.
Installation Considerations for Slope Applications
Slope installations differ from level applications in several important ways. Understanding these differences ensures successful outcomes.
Site Preparation on Slopes
Slope preparation focuses on creating a stable, smooth surface for panel placement. Remove loose material, debris, and vegetation that would prevent panel contact with subgrade. Fill existing rills and gullies with compacted material to create uniform slope surface.
Grade the slope to design profile if significant regrading is required. On severely eroded slopes, this may require importing fill material to restore original grades before geocell installation. Compact any fill material thoroughly before proceeding.
Unlike parking lot applications requiring elaborate aggregate base courses, many slope erosion control installations place geocells directly on prepared native soil with only the geotextile separation layer. The erosion control function doesn’t require the load distribution that parking applications demand. However, unstable or highly erodible soils may benefit from a thin aggregate base layer for additional stability.
Establish drainage control before installing geocells. Temporary diversions keep water off the work area during installation. Identify where concentrated flows will occur and plan for appropriate treatment at those locations, potentially with heavier cell depths or aggregate infill.
Working Safely on Slopes
Slope work presents safety challenges absent from level installations. Establish safe access routes for workers and materials. Consider fall protection requirements for steep slopes. Plan material staging to minimize carrying heavy loads up or across slopes.
Equipment access varies with slope grade. Moderate slopes may allow tracked equipment to work directly on the slope face. Steeper slopes require equipment working from top or bottom edges, with material distribution by hand or specialized slope equipment.
Install from top to bottom when possible. This allows workers to stand on completed sections while installing the next row below. Each completed section provides stable footing for subsequent work.
Weather monitoring matters more for slope work than level installations. Wet conditions make slopes slippery and dangerous for workers. Rain during installation can cause erosion on unprepared sections. Schedule work around weather patterns when possible.
Panel Expansion and Placement on Grades
Expanding panels on slopes requires techniques adapted from level applications. With the panel lying on the slope, have workers at uphill and downhill edges pull to expansion. The downhill edge expands first, then the uphill edge is pulled to complete expansion.
Stake panels immediately after expansion to prevent downslope creep. Don’t leave expanded but unstaked panels overnight—even slight material movement can shift unsecured panels. Connect adjacent panels before moving to the next section, maintaining system integrity throughout installation.
On long slopes, consider installing in horizontal bands across the slope face. Complete each band—expansion, connection, staking, and infill—before starting the next band below. This approach allows finished sections to support workers and protect against erosion during installation.
Infill Placement on Slopes
Placing infill on slopes presents different challenges than level work. Material can run downslope if placed carelessly. Heavy equipment may not access steeper slopes. Compaction must occur before material can migrate.
For steeper slopes, place infill by hand or with small equipment that can work on the slope face. Start at the bottom of each section and work upward, filling and compacting in bands. This prevents upper material from sliding onto lower work areas.
Fill cells completely on slopes. Partially filled cells on slopes are more vulnerable to washout than on level surfaces because water can flow into and through unfilled cell sections. Overfill slightly (1-2 inches above cell tops) before compaction.
Compact infill using equipment appropriate to the slope grade. Walk-behind plate compactors work on slopes accessible to workers on foot. On steep slopes where workers need fall protection, hand tamping may be the only practical compaction method. Make multiple passes to achieve adequate density.
For vegetated slopes, consider hydroseeding immediately after infill placement and compaction. Seeds establish best when applied to fresh, moist soil. Hydroseeding equipment can reach many slopes that hand seeding cannot access efficiently.

BaseCore’s team supports erosion control projects from initial assessment through installation completion. Understanding how to work effectively with your representative ensures you get accurate specifications and smooth project execution.
Project Information to Gather
Before contacting BaseCore, document your slope conditions to enable accurate recommendations. Measure or estimate the slope area in square feet. Determine the slope grade—either measure the vertical rise over horizontal run, or estimate using percentage or ratio notation.
Photograph the slope from multiple angles, capturing any existing erosion features, drainage concentrations, and surrounding context. Note the soil type if known, or describe what you observe—clay, sand, rocky, organic content.
Identify the water sources affecting your slope. Does the slope receive only direct rainfall, or does upslope drainage concentrate on certain areas? Are there culvert outlets, roof drains, or swale terminations that discharge onto the slope?
Define your objectives. Is this purely erosion prevention, or do you also need vegetation establishment, aesthetic compatibility, or specific species support? What’s your timeline—routine maintenance improvement, or emergency response to recent erosion damage?

Frequently Asked Questions
How steep a slope can geocells stabilize?
BaseCore geocells routinely stabilize slopes up to 1:1 (45 degrees) with proper cell depth, anchoring, and installation. Slopes steeper than 2:1 require 6-8 inch cell depths and engineered anchoring systems. Consult with your project manager for slopes exceeding 1:1 grade.
How quickly can vegetation establish in geocell systems?
Grass vegetation typically provides meaningful erosion protection within 6-12 weeks during growing season. Full establishment with dense root development occurs within one to two complete growing seasons. Native species and shrubs may require longer establishment periods.
Will geocells work on post-wildfire hydrophobic soils?
Yes. Geocells hold imported topsoil above the hydrophobic layer, allowing vegetation to establish while the water-repellent condition naturally degrades over 2-5 years. This approach succeeds where direct seeding on burned soils fails.
What maintenance do geocell slope installations require?
Properly installed vegetated slopes require only normal landscape maintenance—mowing if desired, occasional inspection after major storms. No regrading, re-seeding, or structural maintenance is typically needed during the system’s 15-20+ year lifespan.
Can geocells handle concentrated water flow from culverts or drainage structures?
Yes. Use 6-8 inch cell depths with aggregate infill at high-velocity discharge points. Transition to vegetated cells on adjacent slopes where scour velocity decreases. Design concentrated flow areas with your BaseCore representative to ensure adequate protection.
Conclusion: Permanent Solutions for Slopes That Won’t Stay Put
Hill erosion control challenges that defeat temporary treatments require permanent infrastructure solutions. Geocell technology provides that permanence by addressing erosion mechanisms at their source—confining soil against gravitational and hydraulic forces while supporting the vegetation establishment that delivers ultimate long-term protection.
Whether you’re protecting a residential hillside, restoring fire-damaged public lands, stabilizing highway embankments, or managing park trail erosion, BaseCore geocell systems offer specifications matched to your conditions and objectives.
