Swellable waterbar for sealing construction joints.
Suitable for use sealing construction joints against water leaks to:
A hydrophilic acrylate polymer waterbar, which swells when activated by moisture. Offering high elasticity and high tensile strength, Newton 315 Polymer-Waterbar can be used to seal the structure 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, 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.
Consult manufacturer for installation recommendations.
Features and benefits:
Newton 315 Polymer-Waterbar is glued to one side of the construction joint prior to the placement of the next concrete element that forms the joint.
Newton 309-M – adhesive with very high bond characteristics.
To concrete and mortar, the application can be enhanced by the use of masonry nails at approximately 250 mm centres.
White matt finish
TPE with hydrophilic polymers
Varies due to nature of product - can swell up to nine times its original size
Three sizes available: 20 mm x 10 mm x 10 m coil - Code 315-10, 20 mm x 5 mm x 20 m coil - Code 315-5, 20 mm x 2 mm x 20 m coil - Code 315-2.
