Geosynthetic Clay Liners (GCL) with Geomembrane Backing

What is Geosynthetic Clay Liners?

PIONEERTEX BENTONITE MAT is also called Geosynthetic Clay Liner. It’s a geocomposite of multi-layer membrane composed by:

• a 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.

What’s the application of GCL?

BENTONITE MAT(GCL) 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(GCL) 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.

PIONEERTEX GCL COMPETITIVE ADVANTAGE:

PIONEERTEX BENTONITE MAT (GCL) was made of nonwoven geotextile, PP woven geotextile and bentonite powder/granular by needle punch process.

It works as the water shield for a lot of waterproof project such as fish pond, landfill and all some chemical waterproof anti-sewage pond.

PIONEERTEX has been in GCL field more than 20 years since 2003.

We have 5 kinds of GCL to offer as below:

1. Standard GCL 4500 and GCL 5000;

2. Scrim reinforced standard GCL 4500 and GCL 5000.

3. Anti-salt GCL
   

4. Standard GCL bonded with HDPE geomembrane on one side;

5. Standard GCL bonded with HDPE geomembrane on two dies;

GCL could be made of bentonite powder or granular as client requested.

We are looking forward to receiving your inquiry.
