VOLGRIP HP is a pre-cast waterproof self- gripping to concrete bentonite, coupled with an MDPE membrane. The VOLGRIP HP structure is made of a non-woven and porous textile, with interposed sodium bentonite, mechanically assembled through a needle-punching system, to which an MDPE membrane is glued and the entire assembly conveys an insuperable self- containment capacity to the product with unique waterproofing characteristics.
To protect and waterproof underground concrete structures from constant or fluctuating and percolating groundwater.
