Bentonite waterproofing properties are extensively exploited to stop water leaks. Thus, bentonite-based waterproofing products are employed in canals, docks, ponds, and landfills, in the latter case to prevent drainage water from seeping through. Our bentonite-based products have for many years been employed in landfill basal linings, vibro-sealings, and in waterproofing works in general. As to cut-off walls, please refer to the specific section. The perfect execution and excellent long-term results of large-sized works provide ample evidence of the quality of our products.
