Geosynthetic Clay Liners by AAA Metal Suppliers
AAA Metal Suppliers has introduced the Yuan Da range of Geosynthetic
Clay Liners to Australia. These GCLs are manufactured using natural sodium bentonite
needle punched between high quality woven and non woven geotextiles. Fine American
needles randomly needle-punch the fibres from the non-woven polyester fabric through
the bentonite clay to the woven polypropylene fabric beneath. This process results
in an even waterproof layer and a strong mechanical bond between the fabrics. Yuan
Da GCL can be manufactured in grades from 3700g/m² to 5500g/m².
Benefits
- Yuan Da is ISO9001 accredited and each batch of Geosynthetic Clay Liner is tested
to ensure that it meets the required specifications.
- Production capacity is over 5 million m2/year and the liner can be shipped directly
to any port in Australia, thus saving on freight costs.
- 5.8 metre wide rolls are supplied on strong PVC or steel cores to reduce installation
costs. Bentonite is impregnated along the overlapping edges to create a watertight seam.
- All products are fully guaranteed.
- Yuan Da GCLs have been used on major civil projects in China, Europe and South America.
Yuan Da's range includes a PE Bonded Geosynthetic Clay Liner. This PE bonded GCL is
manufactured by laminating a flexible polyethylene liner to a GCL. Its coefficent of
permeability, k=4.5 x 10-12m/sec, is comparable with plastic liners. PE bonded GCLs
are recommended:
- For pond and dam applications exposed to high hydraulic heads;
- Where a GCL is exposed to wetting and drying cycles; and
- Where a GCL is placed against saline soils.
