Four-Layer Coated Bentonite Waterproof Blanket GCL Geosynthetic Clay Liner for Mining

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.Four-layer coated bentonite waterproof blanket GCL geosynthetic clay liner price

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. Property line construction applications include soldier pile and lagging, metal sheet piling, shotcrete and stabilized earth retention walls. Applications may include structures under continuous or intermittent.

General within 3-7 days after received the deposit. 4. why should you buy from us not from other suppliers? Hongyuan International Co., Ltd is one industrial and trading enterprise, with the production intelligence of geomembrane, geotextile, GCL(Geosynthetic clay liners) and geotechnical materials. 5. Can you produce the product according to customers' requirements? Sure, we are professional manufacturer, OEM and ODM are both welcome. 6.Why geosynthetic clay liner can be waterproofing? Bentonite has good adhesion, swelling, colloidal dispersion, thixotropy and cation exchange properties. When bentonite is hydrated, water molecules are adsorbed along the surface of the Si-Al-Si structural unit, which increases the distance between adjacent structural units. After hydration, the surface cations of bentonite are in a hydrated state, and after absorbing H2O, it becomes saturated and becomes a gel, and its durability can reach 200 years. In the confined space, the continuous water absorption and expansion make the waterproof blanket layer itself dense and its volume increases, so that it has a waterproof function by forming a negative pressure inside. Its permeability can be reduced to 10~9cm/s, and it is almost watertight.
