Products Description
most popular bentonite membrane for waterproof projects
GCL-4 consists of a layer of bentonite encapsulated between two geotextiles (a nonwoven and a woven polypropylene geotextiles), needle punched together and laminated on one side to a polyethylene membrane for maximum performances under a wide variety of field conditions. This integrated matrix of bentonite and needle punched fibers provides high shear strength and allows the GCL-4 to keep low permeability even in presence of adverse installation conditions. The GCL-4 has high internal shear strength characteristics for steep slope applications.
APPLICATIONS:
GCL-4 is designed for below-grade vertical
and horizontal structural foundation surfaces.
Typical cast-in-place concrete applications
include backfilled concrete walls, earth-covered roofs, structural slabs, tunnels, and property line construction. Applications may include structures under continuous or intermittent. Hydro-static pressure. Where contaminated ground-water or salt-water conditions exist, use GCL-4 with contaminant resistant sodium bentonite. GCL-4 resists higher levels of the following contaminant’s:
nitrates, phosphates, chlorides, sulfates, lime
and organic solvents.
