What is the 7 mm x 25 mm Hydrotite strip used for?

This profile (RSS/CJ size suited to standard construction joints) is bonded along the centre line of cast in-situ concrete joints to provide a self-expanding hydrophilic seal.

Do I need site welding or intersection pieces?

No. Lengths join with simple butt joints, and the strip can be bonded to traditional PVC waterstops where details transition. This removes the labour and risk of hot-knife welding.

How much joint does one 10 m roll cover?

One 10 m roll covers 10 linear metres of joint. Order spare length to allow for overlaps and detail returns.

Can it bond to rough or uneven concrete?

Yes. Where the substrate is too rough for the self-adhesive backing alone, bed the strip in Leakmaster LV-Z gun-grade waterstop to maintain continuous contact.

Does it work through repeated wet/dry cycles?

Yes. The co-extruded design is unaffected by repeated wet and dry cycles, making it suitable for tanks and below-ground structures that experience fluctuating water tables.
