Bentofix is an extremely versatile clay-based lining product. Once hydrated, Bentofix is an effective barrier against liquids, vapours, and gases.
With over two decades of successful installations, the range of Bentofix applications is virtually limitless:
Strong and durable nonwoven geotextiles encapsulate and protect the layer of sodium bentonite ensuring its long-term performance. And since Bentofix contains highest quality sodium bentonite, an immediate swelling following installation is ensured to safely self-seal any unexpected mechanical damages. Because of its immense elongation capacity, Bentofix shows a long-term adjustment to earth deformations, such as differential settlements. Steep slope applications are easily accommodated by Bentofix. A unique fibre-bonding process locks the needle-punched fibres into place creating high internal shear strength with unsurpassed creep resistance. Bentofix also addresses the often critical issue of interface friction angles. The mechanically bonded nonwoven geotextiles provide the shear resistance necessary for even the most demanding applications. This fibre reinforcement also prevents lateral migration of the bentonite. Bentofix is clearly superior to conventional compacted clay liners. Bentofix GCLs are certified by government regulators.
Bentofix is Economical
Bentofix provides both economical and environmental advantages. Since Bentofix is equivalent to multiple lifts of compacted clay, it thereby increases the potential containment volume in landfills, yielding additional revenues from tipping fees. Bentofix instal lation is quick and easy; it is simply unrolled on site and overlapped at the joints. From a logistical point of view, the advantages of Bentofix are also easy to see: one truckload of Bentofix covers 4,000m² compared with only 40m² (500mm thick) for a load of clay.
Bentofix is Simple
Field testing and sampling from completed claycovered areas are a thing of the past with Bentofix. The manufacture and quality control laboratory programme of Bentofix means it arrives on site with the necessary test results, ready for installation. Compaction and moisture content testing are also eliminated with Bentofix. »Unroll and cover« is the motto of Bentofix installations. There is no easier way to do it.
