Newton 315 Polymer-Waterbar is a hydrophilic, acrylate polymer waterbar, which swells when activated by moisture. It is characterised by high elasticity and high tensile strength. Newton 315 Polymer-Waterbar can be used to seal the structure against water leaks to cast-in-place concrete 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, Newton 315 Polymer-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.
