Hydrotite is the original expanding rubber seal used in a variety of applications for sealing joints against water penetration.
How does Hydrotite work?
IInitially developed for sealing segmental concrete tunnel linings, Hydrotite is a compound of polychloroprene (Neoprene) and hydrophilic resin. When in contact with water and allowed to expand freely (depending on the grade and water conditions), Hydrotite will swell up to 7 times its original volume.
In practice, Hydrotite should be confined in a joint and will expand to fill the gap and create a pressure between the joint faces. By careful selection of the section to suit the application, pressures significantly in excess of 10 bar can be sealed.
Benefits of Hydrotite
- Ease of application and easy to handle
- Time delay on reaction to cope with the British weather conditions
- Cheaper than other alternative as less labour required
- Next day delivery lightweight product - easier distribution
- Controlled expansion due to unique dual extrusion
Hydrotite applications
- Attenuation tanks
- Concrete or cast iron segmental tunnels and shafts
- Construction joints in in-situ concrete walls, slabs and floors
- Box culverts
- Flexible jointed concrete pipes and steel banded jacking pipes
- Swimming pools and tanks
- Fixings to existing concrete or brickwork for penstock valves etc.
