Butyl rubber and bentonite clay based hydrophilic waterstop.
Hydroswell BentoStrip 2.0 is a high-quality butyl rubber and sodium bentonite hydrophilic water bar for the sealing of construction joints in concrete.
BentoStrip 2.0 has high resistance to a wide range of chemicals. Final confirmation about compatibility under specific conditions can be obtained from the manufacturers technical department.
Due to shrinkage of the drying concrete small voids can appear in construction and cold joints, through which water can penetrate. In contact with water, Hydroswell BentoStrip 2.0 swells to seal these voids in the joint.
