Product Description

Product Description

High performance hydrophilic waterstops for sealing construction joints 

For sealing construction joints and penetrations in concrete structures. Waterstop is a strip applied hydrophilic rubber swelling waterstop for use in all kinds of cast-in-place concrete construction joints, as well as steel, concrete and thick-walled PVC (minimum 1/8") pipe penetrations. When exposed to water, the rubber expands, creating a compression seal within the joint or pipe penetration, blocking the passage of water.

FEATURES & BENEFITS

Advantages
Easy to use
Rapid expansion
Dimensionally stable, even at high temperatures
Reproducable swell after wet/dry cycling
Suitable for fresh and salt water
Contains no bentonite
Typical Applications
Vertical and horizontal cast-in-place concrete joints where limited or no movement is expected.
Around through-wall pipe penetrations.
Ideal for new concrete structures or between new and existing concrete.
Benefits:
Easy to use
Rapid expansion
Dimensionally stable, even at high temperatures

RECOMMENDED USES

Use Swelling Waterstop to permanently waterproof horizontal or vertical construction joints, pipe penetrations, between precastelements and other concrete joints. Not for use at expansion joints. Suitable for use in sewage and containment structures. May be used inareas with chloride or sulfate contaminated soils and in contact with sea water.

INSTALLATION NOTES

Easy to install where conventional waterstops would require complex fitting.
Fix in position using adhesive or masonry nails at regular intervals.
A suitable adhesive should be used to fix the seal to metal or PVC pipe surfaces.
On irregular surfaces ensure that direct contact is made between the seal and the substrate along the entire section.
The seal can be exposed to wet site conditions for up to 3 days prior to the placing of concrete, provided it has been coated with an inhibitor to protect it.
A minimum of 70mm of concrete is required on all sides to encapsulate the seal within the concrete.
Joints can be secured by welding, glueing or overlapping.
Swelling is slower in cold conditions and faster in hot.
Typically 28 days to reach full swell in Standard Swell Waterstop.
