Bentonite-based waterproofing product

VOLGRIP LH is a pre-cast waterproof self- gripping to concrete bentonite, specially created for job sites of minor or average difficulty, with limited water head. A carefully balanced quantity of sodium bentonite is the real active ingredient of the system contained within the VOLGRIP LH structure. The structure is made of a non-woven and porous textile, with interposed sodium bentonite, mechanically assembled through a needle-punching system, which conveys an insuperable self-containment capacity to the product together with high performance waterproofing.
 VOLGRIP LH contains a particular sodium bentonite, produced according to particular processing, which encapsulates the sodium bentonite homogenously, preventing contact with the aggressive elements normally found in groundwater. This kind of processing together with the excellent self- containment of VOLGRIP LH maintains its waterproofing power unaltered.
