Geosynthetic Clay Liner (GCL) Hydrostatic Pressure Testers
Water tightness testing for sodium bentonite liners at pressures up to 2.5 MPa.
A GCL hydrostatic pressure tester determines the water pressure a bentonite waterproofing blanket holds back before leakage appears through the mat. Blanket producers, geosynthetics laboratories, and construction QC teams use the result to accept or reject liner rolls against project criteria.
Hydrostatic resistance limits come from the containment design rather than a single international method, typically stated as a pressure level held leak-free for a set duration. Laboratories generally run the test alongside ASTM D5890 swell index and ASTM D5887 index flux work to build a full picture of GCL performance.
