HDPE geomembrane sheet used in a landfill liner system material guide

Landfill Liner Material Guide: HDPE Geomembrane, GCL, and Geotextile Layers

Geomembrane, Geotextile, Landfill / By

A landfill liner is a layered containment system, so choosing one material by price alone can leave critical interfaces unprotected. A landfill liner commonly combines an HDPE geomembrane barrier with geotextile protection, drainage, and sometimes a geosynthetic clay liner (GCL). The correct layer sequence depends on the design, waste and leachate conditions, subgrade, slopes, loads, […]

Geocell Material Guide: HDPE Strip Thickness, Weld Distance, and Cell Depth

Erosion Control, Geocell, Road Construction / By

Geocell panels look similar when folded, but strip thickness, weld spacing, cell depth, and panel dimensions can produce very different site results. Geocell material should be selected by HDPE strip properties, cell depth, weld spacing, panel size, infill, slope or traffic load, subgrade condition, and anchoring method. A deeper or thicker-looking panel is not automatically

Geosynthetic Materials: Types, Uses, and How to Choose for Civil Works

Geosynthetics / By

Civil projects rarely need a generic geosynthetic. They need one material function matched to soil, water, load, geometry, and installation conditions. Geosynthetic materials include geotextiles, geomembranes, geogrids, geocells, geonets, drainage composites, and related products. Choose them by the required function, such as separation, filtration, drainage, reinforcement, confinement, or containment, then verify the project conditions and
