Geoweb® Cellular Confinement System is providing innovative solutions to soil stabilization problems and turf protection needs. Comprehensive resources to design and construct cost-effective solutions to slope, channel, earth retention and load support applications.  Solutions from concept through construction.

 

Developed with the US Army Corps of Engineers

Presto Products Co., a Division of Alcoa Consumer Products, is the originator of the Cellular Confinement System product.  In the late 1970's Presto Products Company co-invented the technology known as cellular confinement or geocell with the US Army Corps of Engineers. (USACE) Waterways Experiment Station.  The early applications consisted primarily of expedient, stabilized sand roads for military vehicles.  Based on the requirements for those load support applications, the USACE established a seam strength standard specified in the 1986 Report GL-86-19 Appendix A of 2000N (400lbs) for 200 mm (8 in.) depth. (In Comparison, Presto's 8" Geoweb is 640 lbs minimum).

Application demands for cellular confinement technology (CCT) expanded beyond the initial scope of that cooperative work into other areas, including slope and channel protection, earth retention and heavy load support applications with a variety of infill materials.  To address these new markets, Presto continued CCT research and implemented product improvements that resulted in today's higher joint strengths, better overall material performance and ultimately higher standards than reported in the original Corps standard.

Geoweb® Applications

Geoweb® Load Support System   Confinement with the Geoweb Load Support System produces a stiff base with high flexural strength. Acting like a semi-rigid slab, loads are distributed latterly reducing subgrade contact pressures. The Geoweb system provides a stable base for paved surfaces and surface stabilization for unpaved surfaces.	Geoweb® Earth Retention System Using a multi-layer design, the Geoweb Earth Retention system allows you to configure structures to your application requirements. Classical methods of stability can be applied to this system and computerized evaluation is available for a broad range of infill, backfill and surcharge parameters.	Geoweb® Slope Protection System Cellular confinement with the Geoweb Slope Protection System confines and reinforces infill material. This greatly improves both vegetated and non-vegetated slopes' resistance to erosive forces. Confinement prevents down-slope migration of individual particles, caused by gravity and hydraulic traction.	Geoweb® Channel Protection System Cellular confinement with the Geoweb Channel Protection System provides flexible, durable protection within defined roughness and stability. Single or multi-layer protection systems are configured to meet a wide range of structural and hydraulic requirements.	Geoblock® Porous Pavement System The Geoblock Porous Pavement System manufactured from up to 50% recycled polyethylene, is a series of interlocking blocks designed to offer turf protection and load support in areas used by heavy vehicles. The units create a flexible structural bridge system within the topsoil layer to support and distribute concentrated loads.

 

Geoweb® / TRM High-Performance Vegetated Solutions

Impressive results from the Geoweb/TRM vegetated infill research for rip rap replacement in channels/drainage ditches, vegetated dams/spillways, and vegetated channel lining systems.

Research Performance Results
 
The Geoweb/TRM system was exposed to varying shear stresses and flow rates for channels with average velocities up to 26.5 ft./sec.  The Geoweb/TRM combined significantly exceeds the limits of separately reported values for both the Geoweb and TRMs.

Geoweb® Benefits

A variety of local infill are available.  Geoweb® protects vegetative root zones, provides a flexible form creating a series of expansion joints for concrete infill and dramatically reduces road base thickness when compared to conventional designs.  Geoweb® is ideal for installation in remote or restricted access sites and provides flexible, durable protection.  Geoweb® gravity and composite retaining walls can be designed to almost any requirement. Geoweb® strengthens structural fills while differential and total settlement is significantly reduced.  Geoweb® reduces pavement deflection, rutting and maintenance costs.  Geoweb® is lightweight and packaged in compact bundles for easy shipment.
 

Textured and Perforated Geoweb® Cell Walls

The Geoweb® Cellular Confinement System consists of solid, textured or perforated cell walls.  The textured Geoweb® has diamond shaped indentations molded into the surface of the cell walls significantly increasing the frictional interlock between the surface of the cell and the infill material.  The Perforated Geoweb® Cellular Confinement System provides optimum frictional interlock between cell walls and concrete, stone or vegetative infill materials while significantly improving drainage characteristics of the designed and integrated Geoweb® Cellular Confinement system.

Geoblock® Porous Pavement System

Geoblock: A System with Integrity: Geoblock® Standard 5150 (GB 5150) and the Geoblock®2 (GB2) Porous Pavement Systems are a series of interlocking, polyethylene paving units designed to provide superior load support and turf protection for emergency and utility access lanes, auxiliary parking, golf cart pathways, trails, and other high-use application areas. The Geoblock® system provides vehicular and pedestrian load support while protecting the grass from the harmful effects of traffic. The Geoblock system covers a larger surface area per unit .5m x 1.0m x 50mm (20" x 40" x 2 inch Nominal), reducing costs and increasing ease of installation. The system's four-sided tabular, interlocking joint design aids in pattern layout and transfers shear loads from block to block.
