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).
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.

GCL Advantages
- Thanks to the impregnation, the joints are immediately sealed
- The product is self sealing. The sodium Bentonite gcl can
automatically repair the common structural damage
- The product have high weathering resistance thanks to our superior
packaging technology
- The pose is allowed under any temperature
- The uprightness infiltration is completely stopped immediately
after the pose
- The pose is fast, safe and easy. Non qualified workers can be
conveniently use.
Plain surfaces (under pit):
- Stretch a clean bed of lean concrete, free from holes and
asperities
Deploy the rolls overcoming it on the joints for 10 cm, and lapel
in necessary in the pit borders Nail the rolls to the lean concrete
every 50 cm
