Newton HydroTank 315 Waterbar – 5mm x 20mm x 20m

High Grade Hydrophilic Waterbar – 5mm x 20mm x 20m.Newton HydroTank 315 Waterbar is a high grade, hydrophilic waterbar with high elasticity and high tensile strength, made from a polymer which swells 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. 

Key Benefits 

• Resistant to permanent water pressure of 2 bar. 
• Delayed swelling – will not swell during the installation process or during the concrete cure. 
• 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 sewage, chlorine and sulphur. 
• Retains integrity even through many wet/dry cycles.

Typical Applications: 

• Sealing construction joints against water leaks to: 
• Concrete and steel intensive structures. 
• Sewage and waste water tanks. 
• Reservoirs. 
• Biogas plants. 
• Underpinning.

Suitable Substrates 

• Concrete. 
• Steel. 
• Brick or concrete block. 
• Ceramic. 
• Plastic.
