Geocell Confinement System (Geoweb)

Geoweb® Cellular Confinement System | The Original 3D Geocell

Engineering Solutions for an Unstable World Since 1982

The Industry Standard for Soil Stabilization If your project demands elite soil stabilization, erosion control, or load support—especially in the unforgiving conditions of the North—there is only one genuine solution. Geoweb®, the original cellular confinement system (CCS), was co-developed by Presto Geosystems and the U.S. Army Corps of Engineers in the late 1970s. As a pioneer in the industry for over four decades, GeoCHEM, Inc. provides the technical expertise and factory-direct inventory required for high-stakes civil engineering projects.

The GeoCHEM Advantage: Original & Genuine

In a market flooded with low-tier imitations, Geoweb® remains the ORIGINAL & GENUINE geocell technology. Invented in America and still manufactured in the USA, this system was engineered to meet the highest military and civil standards. While competitors may claim equivalent performance, Geoweb® is the only system backed by 40+ years of proven research and successful deployment in the world's most extreme environments, including the Alaskan Bush and remote North Slope sites.

How 3D Confinement Works

The Geoweb® system’s 3-dimensional honeycomb structure utilizes the interaction between hoop stresses in the cell walls and the passive earth resistance of the infill. This creates a high-stiffness mattress that:

• Confines Cohesionless Soils: Transforms poor-quality infill into a high-performance structural layer.

• Reduces Base Thickness: Allows for significant reduction in road base depth, saving on material and transport costs.

• Protects Root Zones: Ideal for vegetated slopes and sustainable "green" infrastructure.

• Mitigates Settlement: Significantly reduces pavement deflection and rutting in soft-soil environments.

The ATRA® Key: 3X Faster. 3X Stronger.

For remote projects where labor costs and timelines are critical, the ATRA® Key is your primary advantage. In side-by-side field tests, Geoweb® sections connected with ATRA® keys proved to be:

• 3 Times Faster than traditional stapling methods.

• 3 Times Stronger at the connection point.

• Labor Efficient: Requires only one laborer per connection, with no equipment downtime for stapler jams or reloads.

Proven Applications

• Infrastructure: Road Sub-Base, Parking Lots, Intermodal Yards, and Rail Ballast Stabilization.

• Environmental: Slope and Shoreline Protection, Channel Lining, and Dike/Levee Fortification.

• Remote Access: Granular Soft Access Roads and Foundation Mattresses for unstable terrain.

• Erosion Control: Creek/River Bank Stabilization and High-Performance Vegetated Solutions.

The GeoCHEM Engineering Advantage

Why industry leaders choose Geoweb® for mission-critical stabilization:

• Optimized Logistics: Lightweight and packaged in compact, nested bundles for cost-effective shipment to remote or restricted-access sites.

• Local Infill Versatility: Engineered to utilize native on-site infill, dramatically reducing material transport costs.

• Base Thickness Reduction: Significantly reduces required road base depth compared to conventional designs, saving time and resources.

• Flexible Structural Form: Acts as a series of expansion joints for concrete infill, providing durable protection that accommodates ground movement without the cracking seen in traditional slabs.

• Settlement Control: Strengthens structural fills while significantly reducing both differential and total settlement, rutting, and long-term maintenance costs.

Interface Physics: Textured & Perforated Cell Walls

The performance of 3D confinement is found in the interlock.

• Textured Geoweb®: Features diamond-shaped indentations molded into the cell walls to maximize frictional interlock between the polyethylene surface and the infill material.

• Perforated Geoweb®: Provides the ultimate mechanical interlock for concrete, stone, or vegetative infill. These strategic perforations also significantly improve lateral drainage and moisture distribution across the system, critical for slope and shoreline stability.

Geoweb® / TRM: High-Performance Vegetated Armor

An advanced, sustainable alternative to traditional rip-rap.

GeoCHEM provides specialized Geoweb®/TRM (Turf Reinforcement Mat) integrated solutions for high-velocity channels, drainage ditches, and vegetated spillways. This system is designed for environments where traditional vegetation cannot survive hydraulic shear stresses.

• Research-Proven Performance: In rigorous testing, the Geoweb/TRM system was exposed to shear stresses and flow rates with average velocities up to 26.5 ft/sec.

• Engineered Synergy: The combined system significantly exceeds the performance limits of either component used independently, offering elite protection for dams and levee fortifications.
