Bentofix® GCL

Bentofix®, also known as geosynthetic clay barriers (GBR-C) are high performing, needle-punched, reinforced composites that combine two durable geotextile outer layers and a uniform core of high-swelling powder sodium bentonite clay. This forms a uniform, multi-directional, shear-resistant hydraulic barrier with self-sealing and re-healing characteristics suitable as a barrier for contamination applications in dams, basins of cut-off trenches, or as a replacement for traditional compacted clay layers.

Bentofix ® is available in various grades which can vary in the quantity and composition of the bentonite powder to achieve varying degrees of hydraulic conductivity and sealing capabilities. The product can also be manufactured using nonwoven geotextiles or a combination of woven/nonwoven where additional tensile strength, CBR or interface friction performance is required, for example, on steep slopes.

Bentofix® grades can be produced to customised requirements and in conformance to industry accepted material specifications including GRI-GCL3
