Newton HydroTank 302 Resin Injection Hose Waterbar System - Resin Injection Hose Waterbar

A high performance waterbar system installed within and used for sealing construction joints in earth-retaining and water-retaining concrete structures. When injected with injection resin, the material penetrates into the concrete surrounding the construction joint to permanently seal any cracks, capillaries, pores and honeycombing within the structure.

HydroTank 302 Injection Hose features micro-ports equally spaced over the entire circumference of the hose, and when injected with injection resin at 1-bar of pressure or above the microscopic ports open and the low-viscosity resin penetrates deeply into the concrete surrounding the construction joint.

The injection hose is compatible with both polyurethane and acrylic injection resins, and when installed and injected correctly HydroTank 302 Injection Hose improves the water tightness of the ‘Type B’ waterproof structure by sealing the joints and encouraging improvements in the quality of the concrete placement.

Features and benefits:

• Resistant to permanent water pressure of 2 bar.
• Hose is not displaced or damaged by the concrete compaction process.
• No kicker or rebate required, reducing site labour costs.
• The injection hose is unaffected by weather exposure and site works resulting from project delays.
• Guaranteed continual flow of the injection material due to the star-shaped interior geometry, even if the hose follows sharp bends.
• Quicker to install than conventional waterbars.
• Seals the whole of the joint, not just the few millimetres around the joint and so prevents the water entering the joint and reaching the reinforcement steel.
• Resistant to sewage, chlorine and sulphides.
• Integrity is maintained throughout the building life and is not effected by continuous wet/dry cycles.
• Can be used with or without a kicker.
• Will not ‘free-swell’ into voids and be washed away as is the case with bentonite based waterbars.
• Supplied in 120 m coils. Installed in lengths of 10-12 m. External diameter of 13 mm.
