Hydrotite

Hydrotite is the original expanding rubber seal used in a variety of applications for sealing joints against water penetration.

 

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.

IIn 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 include

- Ease of application
  Easy to handle

- Time delay on reaction
   to cope with the British weather conditions

- Cheaper
   as less labour required

- Next day delivery
   lightweight product - easier distribution

- Controlled expansion
   due to unique dual extrusion

Possible uses Include

A wide range of Hydrotite sections is available to suit a variety of uses. For example:

- 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.
