Slab Raising & Crack Injection Ontario | Quattro Contracting

Slab raising is a process that allows a sunken concrete slab to be releveled. The process involves pumping a substance, in our case lightweight polyurethane foam, under the slab to raise it back to level.

There are a number of reasons why concrete may settle over time:
Poor compaction of the area when the concrete was laid can lead to the slab sinking over time
Erosion can carry away the soil beneath the slab
Drought can cause some soils to shrink creating a void
In industrial settings, the presence of heavy machinery and even the vibrations from nearby highways can cause slabs to sink over time. No matter the reason for the settling the most cost-effective solution is slab raising.
