Geosynthetic Clay Liners Geosynthetic clay liners (GCL’s) are composite products consisting of a thin layer of high purity clay (powdered or granular) sandwiched between two layers of geotextile. GCL’s combine synthetic and natural materials and as such require specialized testing apparatus and techniques.
TRI GCL Testing capabilities include:
Mass of GCL
Mass of Bentonite
Moisture content of Bentonite
Thickness
Wide Width Tensile Strength
Strip Tensile Strength
Grab Tensile Strength
Peel Strength
Permeability (including leachates)
Index Flux
Swell Index
Fluid Loss
Cation Exchange Capacity
Carbonate content
