Newton 315 Polymer - Waterbar 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. Newton 315 Polymer-Waterbar swells up to 9 times it's original size when in contact with water, sealing the joint fully and reliably. Newton 315 Polymer-Waterbar is particularly suited to sealing non-compressed joints such as at the junction between slab and wall.
