Cellular Confinement System

The GeoLok Cellular Confinement System uses interconnected polyethylene cells to confine and stabilize fill materials for slope protection, load support, ground stabilization, and retaining structures. The cells, which range from two to eight in. deep, are made by ultrasonically spot welding 50-mil-thick polyethylene strips that can be perforated to provide drainage and reduce hydraulic pressure and providing. Each section expands to 8 ft x 20 ft and can be secured with stakes or integral tendons. The cell eliminates lateral movement, maintaining the original compaction and load bearing characteristics of the fill. In some slope applications, engineers can fill the cells with concrete to form an articulated concrete mat that conforms to differential settlement. The product is an alternative to armor stone, erosion control blankets, riprap, or gabions. Some applications include:

• Stabilization of aggregate surfaces against rutting under wheel loads.

• Stabilization of pavement base materials against long-term deformation.

• Erosion and surface sloughing prevention on slopes.

• Scouring reduction within channels.

• Construction of vegetated earthen retaining walls to blend with natural surroundings.
