Product Description
Geosynthetic Clay Liners (GCLs) are needle-punched reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier.
The sodium bentonite clay is a naturally occurring clay mineral that swells as water enters between its clay platelets.
When hydrated under confinement, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
Application:Golf course ponds /Stormwater management ponds /Recreational ponds/Landfill cap closures / base liner / Dams/dikes / Vertical trench cutoff Barrier / Groundwater protection cover / Environmental protection barrier under roads and railways / Secondary containment for above ground tanks.
