Expanding Foam
Expanding Foam for Underpinning Homes and Other Structures.
Expanding Foam* for Underpinning and Raising and Re-levelling Homes
The Uretek Method is the modern, very advanced technology for rectifying structural problems caused by ground subsidence.
Uretek does this by injecting expanding structural resins into foundation ground. Invented in Finland 30 years ago and now proven throughout the developed world, the Method is unique and patented.
Underpinning by Uretek expanding foam offers many advantages:
- Fast! Uretek re-levels houses taking between just half a day and two days in most cases.
- Occupants don’t need to move out.
- Very little furniture needs to be moved.
- There’s no excavation. No concrete. No water . No mess.
- Injected Uretek structural resin is harmless to the environment. It’s inert, won’t break down and won’t leach into the water table.
* Expanding resins used this way are far from ‘foams’, because when injected and contained by soils and the structure above them, they become extremely strong; whereas the term ‘foam’ can suggest weakness.
When required Uretek resin formulae can be used to produce huge lifting power even greater than 1000 tonnes per square metre.
The Uretek Method of Using Expanding Foam for Re-levelling Roads, Airport Runways and Similar Concrete Slab Surfaces.
Uretek expanding resin foam injection is now widely used across a range of applications including factory and warehouse floor re-levelling, road bridge approach slab re-support and levelling.
Many of the world’s major airports have been re-levelled by Uretek, as have railway bridges and platforms and important dockside facilities.
