Geosynthetic Clay Liners ( GCL)-Bentonite Mat in poweded form with 0.2mm PE film backing for landfill waterproof project
DESCRIPTION
BENTONITE MAT, it's a line of multilayer membrane composed by:
One layer of polypropylene fabric (weft and warp) with exceptional tearing and mechanical resistance for the floor side.
inside by a non-woven fabric in PP saturated with nano grains of natural sodium Bentonite with high water absorption index.
In the front side a needled, micro punctured in order to allow partial extrusion of the Bentonitic gel. This side is impregnated with a 0,7 kg/sqm of miconized Bentonite.
The three layers are needled together to give to Water Shield excellent weathering properties until grounding. This structure can effectively block the nano grains of Bentonite from movement.
The result of this exclusive manufacturing process is a waterproof membrane with autosealing properties, with excellent weathering resistance, perfect adherence to the upper structure, extremely high puncture resistance (suitable for difficult surfaces with emerging ridges and stones, not regulars, not plane, or earthwork performed by mechanicals vehicles).
BLACK PE FILM ON THE BACKING COULD BE 0.2 or 0.3MM.
Application:
BENTONITE MAT is used in suitable for intensive use in civil engineering, like building or road construction, where the maximum protection from water infiltration is needed. Even an irregular slope course don't affect at all the performance of Water Shield.
BENTONIT MAT is a versatile product, and can be adapted to different situations, but offer it's best for construction use and when the maximum resistance to traction and puncture resistance is needed. This thanks to the impregnation and use of double fabric (weft and warp) on the outer sides.
