On the day of your job, injection holes are strategically drilled into the concrete slab that requires lifting. The equipment is contained in a trailer and has a sufficient length of hose to accommodate the location. Our equipment remains parked, while our crew pulls out enough hose to reach the area being repaired.
Polyurethane foam engineered specifically for concrete lifting is injected as a two-part liquid beneath the slab, infiltrating all air spaces to fill voids, and raising it to the correct level.
The concrete lifting foam has an average reaction time of 12 seconds. Within those 12 seconds, the foam travels in about a 6-foot diameter beneath your concrete, throughout the voids & then expands in a slow and controlled fashion.
After the injections are complete, the holes are patched with a fibre-reinforced cement patching mortar that is matched closest to the colour of your concrete. Concrete lightens with age due to UV-ray exposure, and the same goes for our fibre-reinforced cement patching mortar.
READY TO USE
The average driveway or sidewalk repair typically takes 1-2 hours based on the scope of your project. Interior floors can take up an entire workday depending on the size of the lift and any unforeseen voids beneath.
