EnviroFIX Dam Lining System
EnviroFix Thermal Lock Geosynthetic Clay Liners 9GCL’s) are needle punched reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to
The sodium Bentonite clay utilised in EnviroFix Thermal Lock is a naturally occurring clay mineral that swells as water enters between its clay platelets. When hydrated with confinement, the Bentonite swells to form a low permeability clay liner with the equivalent hydraulic protection of approximately one meter of compacted clay.
EnviroFix Thermal Lock is produced by distributing a uniform layer of the sodium bentonite between two geotextiles. Fibres from the upper nonwoven geotextile are then needle punched through the layer of bentonite and incorporated into a lower geotextile (either a woven or nonwoven/woven composite). This process results in a strong mechanical bond between the fabrics.
A proprietary heat treating process – the Thermal Lock process is then used to modify and more permanently lock the

throughthe core and the roll is suspended from a loading frame. The roll is then either unrolled, or the free end is secured in an achortrench and the suspended roll is slowly backed away.

GCLs must be properly confined by a minimum cover soil layer before being allowed to hydrate fully. Please see detailed installation guide for more details.REQUEST A QUOTE
