A high grade, hydrophilic waterbar with high elasticity and high tensile strength, made from a polymer which swells when in contact with moisture. Ideal for sealing structures against water leaks to both cast-in-place concrete and precast construction joints.
The swelling is achieved through hydrophilic acrylate polymers, which are inseparably embedded within the butylene carrier material. This results in high elasticity and exceptional tensile strength, even when fully expanded within the joint.
Due to its high resistance to acids, alkalis and organic solutions, HydroTank 315 Waterbar can be used to seal joints where aggressive water is expected such as within sewage treatment plants, biogas plants and liquid waste holding tanks.
HydroTank 315 Waterbar swells up to 9 times its original size when in contact with water, sealing the joint fully and reliably. The product is particularly suited to sealing non-compressed joints such as at the junction between slab and wall.
