Site Conditions / Below-grade / BentoPro+
BentoPro+ consists of a 20 mil impermeable high-density polyethylene film, a layer of granular bentonite and spun-bonded geotextile. This composite design produces a high-performance, tough, self-sealing, and vapor-impermeable water barrier. Because bentonite clay swells upon contact with water, it makes for a naturally powerful, self-sealing waterproofing material for post- and pre-applied below-grade foundation applications including freestanding walls, foundations, tunnels, elevator pits and blindside applications to various shoring systems including timber lagging, caissons, sheet pile and shotcrete retention systems. BentoPro+ is highly effective when waterproofing for post- and pre-applied below-grade foundation applications including freestanding walls, foundations, tunnels, elevator pits and blindside applications to various shoring systems including incorporating timber lagging, caissons, sheet pile and shotcrete retention systems.
Highlights

Bentonite provides "active" waterproofing protection that swells when in contact with water.

BentoPro+ self seals when activated.

Can be installed onto green concrete
