Concrete Lifting & Levelling
What is Polyurethane Concrete Lifting?
Concrete lifting and levelling is the cost effective, eco-friendly alternative to busting out concrete. You can lift your existing concrete slab for up to 85% less than removal and replacement. Concrete lifting or raising can usually be done for less than half the cost of pouring new concrete. However, the savings may be even greater, since when concrete raising, the costs of demolition, removal, and landscaping are eliminated.
Polyurethane concrete lifting (our personal favourite) achieves the same results as traditional mudjacking, but with a lightweight material that requires smaller and fewer injection holes and generally a longer lasting result. Also known as foam jacking/poly lifting/foam lifting, polyurethane concrete raising is the latest and greatest concrete repair method available.
The Concrete Lifting Process
On the day of your job, injection holes are strategically drilled into the concrete slab that requires lifting, void filling or under-slab insulation. Our equipment is contained in a trailer, and has sufficient length of hose to accommodate almost any location. Our equipment remains parked, while our crew pulls out enough hose to reach the area being repaired.
Polyurethane foam that is engineered for concrete lifting is injected as a two-part liquid beneath the slab. The foam jacking material will infiltrate all air spaces to fill voids, and raise it to the correct level. Our lifting techs are equipped with a vast knowledge of all of the products and concrete construction in general in order to work with this specialty equipment and products.
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 & expands in a slow and controlled fashion.
Our lifting technician will “bunny hop” from hole to hole in order to lift your concrete slab to avoid breaking it. With use of our specialty equipment, knowledge and experience this is extremely rare.
Post-Lift
After the injections are complete, the holes are patched with a fibre-reinforced patching material 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 patching compound.
Customers may have broken areas of concrete needing to be patched, or gaps in between adjacent slabs that need to be filled for preventative measures. Depending on the width and length of the crack, break or gap, the material used is decided at the time of the estimate. Each product will be priced out accordingly. This part of the job is weather-permitting. If it’s raining outside, patching and caulking must be left until the sun is shining.
The average driveway or sidewalk repair typically takes a 1-2 hours based on the scope of the project. Garage floors, basement floors and most interior floors can take up an entire work day depending on the size of the lift and the voids we cannot see beneath. Each and every job is different.
…At last, your concrete slab is ready for use immediately after our crew is done!
