[1]: CETCO® RESISTEX®, geosynthetic clay liners are engineered to provide the highest level of chemical compatibility in extremely aggressive leachate environments such as coal combustion product storage facilities, mining operations, and
industrial waste storage facilities.
✧✧RESISTEX® geosynthetic clay liners were tested against various leachates including, but not limited to, samples from Electric Power Research Institute (EPRI) and other industrial leachates, and should be considered as guide only. CETCO®
offers project-specific compatibility testing to verify the suitability of CETCO® products. GCL mechanical properties can be tailored to meet project-specific geotechnical engineering requirements.

[1] Flux is defined as " Flow rate/unit area " which can
be converted to permeability using the equation:
Permeability = flux/hydraulic gradient
[3] CL = Canal liner
LL

(5 psi) and 14 kPa (2 psi) head pressure
SIC = Surface impoundment cover
