Properties:

Compared with the compacted clay liner, with small size, light weight, soft flexibility, nice tightness,

strong shearing strength, its construction is simple and convenient, and it's adaptable to the uneven

settlement etc.

Usage:

The product is mainly applied in environmental projects such as waste landfills, underground water

reservoir and underground infrastructure projects. It can effectively solve the tightness,isolation and

seepage control with apparent effect and strong damage resistance.

Construction suggestions:

1.The laying work of GCL should overlap along the water flow direction,which also means “first bank ,then bottom”
2.The GCL should be overlapped neatly and the overlapping length≥300mm.
3.Put bentonite in powder 0.4kg---0.6kg/m on the overlapping place evenly.
4.One or two folding can be done if necessary,and their best length is 100mm
5.The white non-woven fabrics of GCL should be laid upwards then cover them with
60mm--100mm concrete.
6.The laying height on the edge should be 100mm higher than the designed height.
