HYDROTITE HYDROPHILIC CHLOROPRENE RUBBER WATERSTOP

Description 

Hydrotite Hydrophilic Chloroprene Rubber Waterstop used to seal concrete construction joints against water leakage. It combines an expanding blue hydrophilic section and a non-expanding black chloroprene rubber section, designed so that expansion occurs across the joint to form a tight compression seal.

When exposed to water, Hydrotite expands up to eight times its volume and changes from dark blue to light blue, allowing visual inspection for premature expansion. It can withstand water pressure up to 50 metres and is widely used in both water-retaining and water-excluding structures.

A delay coating prevents early expansion during concrete pouring. Hydrotite can shrink when dry and re-expand when exposed to moisture again, maintaining effectiveness through repeated wet and dry cycles. It is known for being durable, cost-effective, and easy to install, ensuring long-term joint integrity in concrete construction.


 

Uses

Hydrotite is to be used where watertight integrity is the prime issue. Typical applications where there is a need to achieve a water seal include:  

• Sewerage Treatment Plants

• Water Treatment Plants

• Reservoirs

• Water Tanks

• Swimming Pools

• Tunnels

• Subway Stations

• Basements

• Pits

• Pipe Penetrations

Advantages

• Easy to handle and install

• Excellent adhesion to concrete surfaces (Outstanding physical properties)

• Profiles with self-adhesive backing allow for simple and fast installation processes

• Co-extruded design means expansion is directed across the joint for maximum seal (Capable of sealing heads of water up to 50 metres)

• Unaffected by repeated wet and dry cycles

• No site welding is required for joining processes

• Has a delay coating to help prevent premature expansion (Changes colour as a visual alert to let you know it has expanded)

• No need for special intersections, joining is by simple butt joins

• Can be applied to rough surfaces using Leakmaster gun grade waterstop

• Can be joined to traditional PVC waterstop. Refer CORKJOINT® for further information.

• No compaction or displacement problems

• Non-toxic and non-hazardous. NSF certified.

• No need for split forming
