Providing the most comprehensive geosynthetic lines in the industry

EGA 20

BaseLok GC20T

Baselok GeoCell

GC20T sections are manufactured from (58) 300" long HDPE strips. Section is 29 cells L X 21 cells W. Weld spacing is 14.0 in ± 0.12 in. Cell density is 34.6 cells/sm. Cell walls are textured with rhomboidal indentations having a surface density of 140 to 200/sq in. If perforated, 13% ± 3% of cell wall is removed. 
Color: Standard strips are black. (Tan, Green, other colors with no heavy metal content available upon request).
Stabilizer: Hindered amine light stabilizer (HALS) 2.0% by weight of carrier.
Cell Depths: 2" (50mm), 3" (75mm), 4" (100mm), 6" (150mm), 8" (200mm)
