Description :

Newton HydroTank 315 Waterbar is a hydrophilic, acrylate polymer water stop, which swells when activated by moisture. It is characterised by high elasticity and high tensile strength. HydroTank 315 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, 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.

Key Benefits :

• Resistant to permanent water pressure of 2 bar
• Swells up to 9 times its original size
• Very resistant to the high alkalinity of concrete
• Maintains very high elasticity and tensile strength, even when swollen
• Age resistant, no embrittlement
• Resistant to a large range of chemicals (pages 4-5)
• Retains integrity, even through many wet/dry cycles
