General Information

The use of liners in civil and environmental applications is becoming more widespread as there develops a greater understanding of the effects of contaminated ground conditions on structures and the environment.

Global Synthetics are able to offer a wide range of liners that are compatible with the diverse range of applications and contaminants likely to be encountered.

Product Information

Bentofix® Geosynthetic Clay Liner (GCL) is a factory produced wide width rolls of bentonite “sandwiched” between layers of geotextile. GCL’s are an engineered replacement for traditional clay lining of proposed containment structures.

Global Synthetics Geosynthetic Clay Liners offer the designer an engineered equivalency to clay without the costly import and placement and quality control costs associated with this traditional method. The volume of containment may be significantly increased with the use of a Global Synthetics Geosynthetic Clay Liner as the product offers equivalency to very thick layers of compacted clay.

Bentofix® Geosynthetic Clay Liner – XF Series

Bentofix® GCL with nonwoven cover geotextile and woven carrier geotextile. An additional surface polyethylene (PE) coating is applied in a liquid state and then allowed to solidify on the carrier geotextile. The additional bonding of a PE coating to the needle-punched, fibre reinforcement is permanently locked and increases the pull-out resistance as well as the internal shear strength. The mass coating is 500gsm (0.5mm thick) minimum and upto 1000gsm (1.0mm thick) for the friction coating and exceeds the GRI-GCL3 (USA) minimum specification requirements for coated GCLs. Also features self-sealing side overlaps. The coated (friction), Xf-type GCL is used predominantly in the following applications: an immediate barrier against Radon gas; desiccation protection; small root penetration protection; bentonite erosion at high water heads and underlying coarse subgrades; or for secondary containment (providing eXtra safety factor) against hazardous liquids. The other added benefit of a friction coating is the increased interface friction value, allowing for steeper side batters, but providing significant protection against internal bentonite erosion and piping for exposed multi-lined landfill cells. Shrinkage reduction from environmental/thermal changes is also an important advantage.



Case Study

Bentofix® – Canal Sealing

After the first pilot project installation of a geosynthetic clay liner (GCL) in a 1 km long section of the Havel-Oder-Waterway in 1997/98, approved by the local German Water and Ship Authority a second project followed shortly after.
