ASTM Test/ Gri GM-13 Standard HDPE Geometric (HDT075)

Our HDS (smooth HDPE) and HDT (textured HDPE) geomembranes are produced from high density polyethylene (HDPE) resins resulting in premium grade geomembranes. They are the most widely used products for lining of solid waste sites, mines, and other fluid containment applications. They are preferred for sites requiring low permeability and exceptional chemical and ultraviolet resistance properties. Resistance to weather, ultraviolet rays, and chemicals makes their use an extremely cost effective alternative in reservoir construction.

With the addition of a textured surface HDT geomembranes provide an excellent abrasion resistance. By utilizing our co-extrusion process this textured surface is manufactured homogeneously with the extrusions of the solid barrier portion of our geomembrane, as opposed to being added after extrusion, thus fully integrating with the sheet during the molten phase of manufacturing. The result is a surface that remains intact regardless of the chemicals which may come in contact with the sheet. Our production capabilities allow us to supply either a single or double sided textured surface.

The addition of a textured surface also allow engineers to increase friction between two layers. This also allows for the designing of steeper slopes, resulting in the added capacity of a site. Sinotech HDT geomembranes also retain all of the excellent properties of our HDS geomembranes.

Unlike other products, our HDS and HDT geomembranes do not contain plasticizers that could migrate and cause premature aging of the liner or other environmental factors; They do not need to be buried for protection. Our geomembranes are also resistant to mold, mildew, fungus, and chemicals normally found in soil.

While manufactured in the standard color of black, both our HDS and HDT can be manufactured to match any color requirements you may have.
