EGA 20

Envirogrid® Adjustable Series

EnviroGrid® adjustable series is designed to provide more flexibility in section size. Section and cell size will change as each section is expanded to the required dimension. Section length can be increased or decreased by adding or subtracting cells at no additional charge.

EGA 20: 21.4 ft panel length, various cell depths, perforated and textured, 29-cell section length. Standard sections are manufactured from 58 strips of HDPE, resulting in a section length of 29 cells and 10 cells wide. Each strip is the appropriate width and 142 inches (3.6 m) in length. Weld spacing is 14.0 in ± .12 in (355 ± 3 mm). Cell density is 35 cells per meter squared. Cell walls are textured and if perforations are required 16% ± 3% of the cell wall is removed.
