Production & Package

BPM Geosynthetic Clay Liners are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. For different projects,it can combine HDPE liner for better waterproof.

Function : When hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay. The excellent properties of tensile and peel strength make the products ideal for many projects.

Application : Geosythetic Clay Liners are widely used in waste landfill capping and cutoff walls to contain pollution,mining base seals, canal and dam liners, lakes and other waterproofing projects.
