Framework For Stability
The Geoweb cellular confinement system was developed through a cooperative research effort with the U.S. Army Corps of Engineers during the late 1970s.
Advanced research, testing and field evaluation have been the foundation of the Geoweb system performance ever since. Today this effort involves a host of facilities, organizations and distributors throughout the world.
The Geoweb cellular confinement system is available in three cell surface and wall types: smooth surface, textured surface and perforated cell wall. The textured cell wall surface has a pattern of specific size and depth diamond-shaped indentations. This unique pattern significantly increases the frictional interlock between the surface of the cell and infill material.
Through the specific hole diameter and pattern, the perforated cell wall provides increased frictional interlock with a broad range of coarser aggregates and concrete. The perforations allow for root lock-up within the wall system, creating a more stable vegetated cover. In addition, the perforations allow lateral drainage through the system, thereby enhancing performance.
Integral polyester tendons, incorporated into the Geoweb system through pre-drilled holes, are used to anchor Geoweb sections and provide additional stability. Tendons may be used when a geomembrane underlay or naturally hard soil/rock prevents anchoring with stakes.
All phases of manufacturing are monitored through statistical process control. Each section will have met certified quality standards before it ships to the job site. In addition, each section is backed by a warranty for materials and workmanship.
Improve the performance of your structural fill in a wide range of load support applications ... from single-layer road bases to multi-layer earth retention structures.
Strength by Confinement
The Geoweb system strengthens structural fill by increasing its shear strength and stiffness. This improvement is a result of the hoop strength of the cell walls, the passive resistance of adjacent cells and the frictional interaction between the infill and the cell walls.
Under load, the Geoweb system generates powerful lateral confinement forces and soil-tocell wall friction. These mechanisms create a bridging structure with high flexural strength and stiffness. The bridging action improves the longterm load-deformation performance of common granular fill materials and allows dramatic reductions in the thickness of structural support elements.
For single-layer load support applications such as road bases or intermodal yards, the cost benefits of the using the Geoweb system are reductions in excavation and fill material. The Geoweb system can be used with on-site granular fill in place of costly imported materials. Because the load is distributed or bridged over soft soils, the thickness and weight of structural support elements can be reduced by 50 percent or more when compared to traditional load support methods.Easy Installation
The Geoweb system is designed with ease of installation in mind. Geoweb sections collapse into lightweight, compact bundles for easy shipment. during installation, sections remain flexible and easy to handle. Various methods are used for expanding the Geoweb sections. Stretcher frames are typically used for installations where dimensional tolerances are critical.
