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).

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


GCL CS is an isolating, non-permeable product which is constructed of a GCL layer bonded to a geomembrane sheet.


USES & FUNCTIONS Thrace Group GCL CS is used in many civil engineering and building applications offering the function of containment.

1. An upgraded mechanical operating parameter.

2. Extreme toughness and durability.

3. A double lined system.

4. Puncture resistance.

APPLICATIONS In landfills, canals & storage reservoirs, tank storage sites, tunnel & building seals, run-off basins, flat roofs, concrete piles and sheet piling, foundation and other subsurface structures.
