Geoweb® Cellular Confinement |
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.
Applications:

|
|
Granular Soft Access Roads, Porous Pavements, Road Sub-Base,
Parking Lots, Inter modal Yards, Track Sub-Ballast, Boat Ramps, Foundation
Mattresses, Dike & Levee Fortification, Concrete Channel Lining And
Protection, Fish Spawning Stabilization, Creek And River Bank Stabilization,
Erosion Control on Steep Slopes, Erosion Protection, Composite And/Or Gravity
Retaining Walls.
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 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.
