EnviroGrid - Model EGA40 -Cellular Confinement Systems - Geocell

Envirogrid EGA 40 standard sections are manufactured from 58 strips of HDPE, resulting in a section length of 29 cells and 5 cells wide. Each strip is the appropriate width and 142 inches (3.6m) in length. Weld spacing is 28.0 in ± .12 in (711 ± 3mm). Cell density is 9 cells per meter squared. Cell walls are textured and if perforations are required 16% ± 3% of the cell wall is removed.

Polyethylene strip shall be textured with a multitude of rhomboidal (diamond shape) indentations. The rhomboidal indentations shall have a surface density of 22 to 31 per cm2 (140 to 200 per in2).
