geotextile bentonite clay liner Geosynthetic Clay Liner (GCL )

bentonite clay liner Geosynthetic Clay Liner Product Description
Geosynthetic clay liners (GCLs) 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. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).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.Technical Parameter Inspection ItemTesting ProcedureTechnical IndexBentonite mass for unit areaASTMD5993≥5.5kg/m2Expansion coefficientASTMD5890≥25mL/2gLow temperature ductilityASTMD5898No impact at -35°CThicknessASTMD5892≥6.4mmTensile strengthASTMD4632≥540NPeel strength of concrete faceASTMD4632≥3.0 KN/ m2Peel strengthASTMD4632≥68NIndicated flowASTMD5887≤1 x 10-8m3/m2/secHydrostatic pressure resistanceASTMD5888≥70PermeabilityASTMD5887≤5 x 10-12cm/secExtension rateASTMD5896≥20Puncture strengthASTMD5894≥635NFeatures:
