Clay Liners are available under the product name Bentomat® CLT (manufactured by CETCO.)

The Bentomat® needlepunching process consistently reinforces the bentonite layer with thousands of high tenacity fibers that resist and transfer the shearing stresses into the encapsulating geotextiles.

The uniform confinement provided by the fibers from this process resist lateral migration of the bentonite clay within the Bentomat® - in either a dry or hydrated state.

The needlepunched fibers are more durable over a wider range of installation conditions and greatly reduce the adverse effects of premature hydration during installation.

With Bentomat®, the clay component is no longer the limiting factor on side slopes. You can replace compacted clay layers on steep side slopes and be assured of low permeability without sacrificing slope stability. The inherent confining stress from the needlepunching also improves the hydraulic properties under low confining stress applications.
