Innovative Site Solutions for Civil Engineering and Construction Projects

When faced with challenging site conditions—whether it’s weak soils, steep slopes, or erosion-prone channels—finding an efficient, long-term solution that minimizes maintenance is essential. Geocells offer just that. These innovative cellular confinement systems (CCS) are a proven solution for load support, retaining walls, slope stabilization, and channel protection applications. Geocells not only improve soil stability but also contribute to eco-friendly, sustainable project designs.

Geocells are three-dimensional, honeycomb-like structures typically made from high-density polyethylene (HDPE). By confining and reinforcing infill materials like soil/vegetation, sand, gravel or concrete, geocells create a stable, load-bearing surface. This cellular system prevents soil movement and erosion, making geocells a versatile solution for stabilizing weak soils and supporting structures such as roads, retaining walls, slopes, and channels.

How Geocells Work

The core function of geocells is to create a grid of interconnected cells that confine and stabilize infill materials. This CCS strengthens the underlying soil and distributes loads more evenly, preventing the movement of infill under pressure. In load support applications—such as roads, parking areas, or driveways—geocells act like a semi-rigid slab.

The geocell structure increases the load distribution angle and spreads vertical stresses over a larger area, which is commonly referred to as the mattress effect. This feature helps stabilize weak subgrades and prevents surface deformation, such as rutting or differential settlement, under heavy loads.

Key Benefits of Geocells

• Soil Stabilization for Weak Subgrades: Geocells are designed to stabilize soils that would otherwise shift or settle under loading. By confining infill materials, geocells create a firm, stable base that can support the demands of roadways, heavy-duty parking lots, or other infrastructure projects. The mattress effect further enhances this stabilization, ensuring that vertical stresses are distributed across a wider area, reducing the likelihood of differential settlement or deformation over time.

• Erosion Control for Slopes and Channels: On slopes and in channels prone to erosion, geocells help prevent soil from washing away during rainstorms or high-flow events. The cellular structure holds soil in place, creating long-term stability and reducing maintenance needs.
• Sustainable and Eco-Friendly: By allowing the use of locally sourced infill, geocells reduce the need for imported materials and minimize the environmental footprint of a project. Their permeable design also promotes natural water infiltration, helping manage stormwater and reduce runoff.
• Cost-Effective with Minimal Maintenance: Geocells are a cost-effective solution for stabilizing weak soils and preventing erosion. Their simple installation process and long-lasting performance mean reduced material costs upfront and less maintenance over time.

Common Applications for Geocells

• Load Support: Geocells stabilize unpaved roads, parking areas, and other surfaces by evenly distributing loads, which prevents differential settlement and rutting.
• Slope Stabilization: On steep embankments, geocells hold soil in place, reducing erosion while allowing vegetation to take root for natural reinforcement.
• Retaining Walls: Geocells offer a flexible alternative to rigid retaining walls, adapting to natural shifts in the landscape and soft sub grade soils while maintaining soil retention.
• Channel Protection: Geocells reinforce the bed and banks of stormwater channels, reducing erosion and ensuring long-term stability, even in high-flow conditions.

Introducing GEOWEB® Geocells: The Original Cellular Confinement System

While geocells are becoming widely used today, GEOWEB Geocells stand out as the original and most advanced system on the market. Presto Geosystems, in collaboration with the U.S. Army Corps of Engineers, pioneered the development of geocells in the late 1970s to address the need for reliable soil stabilization solutions in military and civil applications. This collaboration resulted in the invention of the GEOWEB system, which continues to lead the industry in performance and innovation over the past 40 years.

GEOWEB Geocells are made from high-quality, virgin HDPE, which offers superior strength, flexibility, and long-lasting durability compared to other systems. This ensures that the GEOWEB Geocells can withstand harsh elements and challenging conditions, whether it’s in load-bearing applications or erosion control projects.

The GEOWEB system is a complete geocell system, including ATRA® Accessories such as ATRA Connection Keys, ATRA Anchors, ATRA Tendon Clip, and the ATRA Driver. These components are designed to enhance installation efficiency and long-term performance, providing fast, secure connections that ensure the structural integrity of the entire system.
