Sunken Concrete Solution

Sunken concrete can be a big pain if you have to replace the slab or if it causes you to trip!

Extensive research has found a new alternative for sunken concrete. Now polyurethane foam can be injected through penny-sized holes in the existing concrete which then expands beneath the surface to stabilize weak material and fill empty spaces, which causes the slab to rise up to the original alignment. While strong and durable, polyurethane is also extremely lightweight, reducing the likelihood of further concrete settling.

‘Polyjacking,’ as it’s known, has proven exceptionally effective. This is great news for both homeowners and builders. Just another way polyurethane is innovating – and fixing – our world!
