BentoShield Max is a self-healing waterproofing material specially developed for underground waterproofing. It consists of polymer-modified sodium bentonite granules or bentonite powder and high-strength geotextiles, which, when integrated with concrete, can be directly applied to compacted soil surfaces without the need for a mud slab or protective layer. It is designed for construction areas with foundation depths of 12 meters and above. BentoShield Max forms an interactive barrier system throughout the lifespan of the structure, providing waterproofing and preventing the infiltration of water to safeguard the building.
