Concrete Lifting & Levelling
Polyurethane concrete raising is a more affordable alternative to concrete removal and replacement and a less invasive option compared to mudjacking. This method is less disruptive and offers several advantages over traditional slab raising techniques. At Slab-Jack Kings, our concrete lifting technicians are trained experts with over 10 years of hands-on experience. We provide concrete lifting and leveling services using various concrete raising foam systems, tailored to each project’s needs.
Slab-Jack Kings uses a unique concrete raising foam exclusive to our company, ensuring superior results. Our foam is unrivalled in compressive strength and hydrophobic, designed specifically for our climate and soil characteristics.
Once our foam infiltrates the voids and air spaces beneath the slab, it adheres permanently, strengthening it considerably. This results in:
1. a drastically reduced incidence of surface hairline cracking from ground movement and
2. minimized emerging tripping points at significant gaps and cracks where rebar is absent or failing.
Our service areas include Winnipeg and its surrounding areas, most of Manitoba, and most of Northwestern Ontario.
What is Polyurethane Concrete Lifting?
Concrete lifting and levelling is the cost-effective, eco-friendly alternative to busting out concrete. Concrete lifting, concrete raising, slab jacking or concrete leveling 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.
Are there other terms for polyurethane concrete lifting or do they all mean different things?
Yes, there are other terms for polyurethane foam concrete lifting, and they generally refer to the same process. Terms such as polyurethane foam concrete raising, concrete raising with foam, foam jacking, foam concrete lifting, concrete lifting with foam, concrete leveling with foam, poly leveling, polyurethane slab jacking, foam lifting and foam slab jacking, etc. all describe the method of using polyurethane foam to lift and stabilize concrete slabs. These terms are interchangeable and highlight the use of concrete lifting foam in the repair process.
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!
