Newton HydroTank 315 Waterbar for Sealing Structures Against Water Leaks - High Grade Hydrophilic Waterbar

A hydrophilic acrylate polymer waterbar, which swells when activated by moisture. Offering high elasticity and high tensile strength, Newton HydroTank 315 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 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. Consult manufacturer for installation recommendations.

Features and 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

Suitable joints:

• Construction joints, day joints and shrinkage joints.
• Concrete walls above a concrete kicker.
• Within concrete rafts or slabs.
• Concrete slab to concrete or steel wall.
• Concrete slab to brick/ block wall (20 x 10 mm only).
• Joints to precast concrete elements.
• Steel beams protruding through the concrete.
• Ceramic or plastic waste pipe protrusions (20 x 2 mm only).
• Preformed sump chambers within new rafts or slabs (20 x 2 mm only).

Installation:

HydroTank 315 Waterbar is glued to one side of the construction joint prior to the placement of the next concrete element that forms the joint.

Recommended adhesive:

HydroTank 309 Flexible 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.
