Drainage geocomposites are rapidly replacing gravel drainage layers in containment facilities. These relatively thin materials are required to provide similar or better performance than thick mineral layers. Comprehensive testing is carried out to prove their equivalence to thick gravel drainage layers.

TRI GCL Testing capabilities include:

Physical
Thickness (under load)
Carbon Content
Density
Tensile
Wide Width Tensile Strength
Strip Tensile Strength
Peel Strength
Compressive
CBR Burst Strength
Compressive behavior (rib roll over)
Compressive Creep

Hydraulic
In Plane flow

Durability
Oxidative Induction Time (OIT)
High Pressure Oxidative Induction Time (HPOIT)
