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.
