LANDFILL
LINERS Within a landfill composite liner system,GCLs
are an equivalent replacement for all or part of the traditional
compacted clay component. GCLs effectively minimise system leakage
by providing "intimate contact"with the overlying
geomembrane, outperforming a compacted clay-based composite
liner system. CETCO GCLs provide simple, cost-effective installation,
with superior hydraulic performance.

| SECONDARY
CONTAINMENT Because of the ease of installation, flexibility
and reasonable cost, CETCO GCLs are excellent for secondary containment
of above-grade fuel storage tanks. The details and penetrations
typically foundat such sites are easily ans cost effectively constructed
using GCLs and accessory bentonite or bentonite mastic. |

SURFACE IMPOUNDMENTS
Geosynthetic Clay Liners (GCLs)s are high performance enviromental
liners comprised of geosynthetic carrier components integrated
with a layer of low-permeability Volclay sodium Bentonite |
| LANDFILL COVERS
GCLs are ideal for landfill cover systems, both as the
sole hydraulic barrier component and as part of a composite system
underlying a geomembrane. GCLs resist damage due to freeze-thaw,
dessication cycling and differential settlement, all of which
can damage traditional compacted clay liners. |
