Bentomat - Model CLT -Reinforced Geosynthetic Clay Liner (GCL)

Bentomat CLT is a reinforced geosynthetic clay liner (GCL) consisting of a layer of Volclay® sodium bentonite between two geotextiles, which are needlepunched together and laminated with a flexible textured HDPE sheet. The addition of the HDPE sheet to the GCL increases the hydraulic resistance by an order of magnitude over that of standard GCLs. The textured surface of the HDPE sheet also increases the interface friction between the GCL and adjacent substrate when a greater interface friction is required on certain projects. This product is mainly used in liquid containment and landfill cap applications, but the versatility of the product allows it to be considered in many other applications.
