INTERLoK® Geosynthetic Clay Liners
For Superior Hydraulic Performance
Low permeability geosynthetic clay liners are attained by adding non-biodegradable, high-viscosity polymers to sodium bentonite to even further reduce available pathways for water flow. These geosynthetic clay liners have a maximum permeability 100 times less than conventional compacted clay liners.
INTERLoK geosynthetic clay liners are available in DN, ST, 200R, and SDN configurations.
We build all of our GCLs to be compliant with GRI-GCL3 and their guide specifications can be found for use on the Geosynthetic Institute website.
