Sika® BentoShield® Max LM is a self healing waterproofing membrane that is resistant to contaminated soils, forming an automatic mechanical bond to freshly poured concrete. Consisting of two polypropylene geotextiles, a woven fabric and non-woven fabric, enclosing pre-hydrated homogeneous layer of granular sodium bentonite at a minimum weight of 5000g/m². The two geotextiles are interlocked by a needle-punching process forcing fibres from the non-woven layer through and beyond the woven layer. This process contains and confines the polymer modified bentonite granules and forms a physical link between the geotextiles. A flexible polyethylene layer is integrally bonded to the non-woven geotextile.
