RESIDENTIAL CONCRETE LIFTING PROCESS
INJECTION HOLES
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.
FOAM
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.
PATCHING
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.

How is concrete lifting done?
Concrete lifting is the process of raising sunken or settled concrete slabs back to their original position. Here are the general steps involved in concrete lifting:
Drill holes: Small holes are drilled into the concrete slab in a strategic pattern to allow for the injection of a lifting material.
Inject lifting material: A high-density polyurethane foam or a cement slurry is injected into the holes under the slab. The material expands to fill any voids and lift the slab back into place.
Patch holes: Once the lifting process is complete, the holes are patched with a cementitious material.
Concrete lifting is a fast and cost-effective method of repairing sunken or settled concrete slabs, such as sidewalks, driveways, and patios. It is less invasive than traditional concrete repair methods, such as replacing the entire slab, and the repair can be completed in a matter of hours rather than days or weeks. It is important to consult with a professional concrete lifting contractor to determine the most appropriate method for your specific needs.
What is used for concrete lifting?
There are two common materials used for concrete lifting: high-density polyurethane foam and cement slurry.
High-density polyurethane foam: This is a lightweight and durable foam material that is injected through small holes drilled in the concrete slab. Once injected, the foam expands and hardens, filling any voids under the slab and lifting it back into place.
Cement slurry: This is a mixture of cement, water, and sometimes other additives, such as sand or fly ash. The slurry is injected into the voids under the concrete slab, and as it hardens, it lifts the slab back into place.
Both materials have their own advantages and disadvantages, and the best material for a specific job depends on factors such as the size and location of the slab, the extent of the damage, and the desired outcome. It's important to consult with a professional concrete lifting contractor to determine the most appropriate material for your specific needs.
What are the different types of concrete raising?
There are different methods of raising and leveling sunken or settled concrete slabs. Here are some of the most common types of concrete raising:
Mudjacking: Also known as slabjacking, this method involves injecting a slurry mixture of cement, sand, and water under the concrete slab to lift it back into place.
Foam injection: This method uses high-density polyurethane foam that is injected through small holes drilled into the concrete slab. The foam expands to fill any voids and lift the slab back into place.
Grouting: This method involves injecting a thin slurry of cement and water into the voids under the concrete slab to lift it back into place.
Hydraulic jacking: This method uses hydraulic pressure to lift the concrete slab back into place. It's usually used for larger projects and involves drilling multiple holes in the slab.
The best method for raising and leveling a sunken or settled concrete slab depends on several factors, including the size and location of the slab, the extent of the damage, and the desired outcome. It's important to consult with a professional concrete lifting contractor to determine the most appropriate method for your specific needs.
What is the best method for concrete leveling?
The best method for concrete leveling depends on several factors, such as the size and location of the concrete slab, the extent of the damage, and the desired outcome. Generally, the following methods are considered effective for concrete leveling:
Foam injection: This method involves injecting a high-density polyurethane foam through small holes drilled into the concrete slab. The foam expands to fill any voids and lift the slab back into place. This method is often preferred because the foam is lightweight, durable, and can be injected quickly, resulting in a fast and efficient repair.
Mudjacking: This method involves injecting a slurry mixture of cement, sand, and water under the concrete slab to lift it back into place. Mudjacking is effective for larger slabs or those with extensive damage. However, it is a more invasive process and may take longer to complete than foam injection.
Grouting: This method involves injecting a thin slurry of cement and water into the voids under the concrete slab to lift it back into place. This method is often used for smaller or more localized repairs.
It's important to consult with a professional concrete leveling contractor to determine the most appropriate method for your specific needs. They can evaluate the extent of the damage and recommend the best repair method for your situation.
How thick concrete is needed for a lift?
The thickness of the concrete needed for a lift depends on the extent of the settling or sinking and the method used to lift the slab. In general, a minimum of 4 inches of concrete is needed for most concrete slabs, including sidewalks, driveways, and garage floors. However, if the slab has settled significantly, it may require additional concrete to be added to raise it back to its original level.
When using foam injection or mudjacking to lift the slab, the thickness of the concrete does not need to be increased. Instead, the foam or slurry is injected under the slab, filling any voids and lifting the slab back into place.
It's important to consult with a professional concrete lifting or leveling contractor to determine the appropriate thickness of the concrete needed for a lift, as well as the most appropriate method to use for your specific situation.
