Concrete lifting (mudjacking/slabjacking)

Concrete lifting, which is also known as mudjacking or slabjacking, corrects sunken and uneven concrete by creating a solid foundation under the problem area. The concrete is carefully and evenly raised to the proper height by injecting either polyurethane foam or a grout mixture underneath the sunken slab or concrete area.

Void filling

An injection of grout or polyurethane foam that fills the space between a foundation or concrete slab and the soil beneath the foundation or slab. Voids are usually caused by erosion.

Soil stabilization

The treatment of soil to increase or maintain its stability or improve its solidity and strength using specialized grout or polyurethane foam. The result makes the ground stronger and more stable helping to prevent erosion and settlement.

Concrete repair

Repairing concrete rather than replacing is a cost effective solution. Sunken or unlevel concrete most times can be repaired for less cost and in less time than replacement.

Diverting water or water cut-off

Polyurethane can be used to ‘cut off’ even gushing water of high pressure and speed. It can also be used to divert water away from unwanted areas.

A few examples;

    • warehouse floors
    • warehouse expansion joints
    • commercial office space
    • loading dock ramps
    • bridge aprons
    • highways
    • culvert filling
    • industrial shop floors


    • underpinning piling
    • parkades
    • manhole cracks
    • leaky culverts

Using the most up to date equipment and the latest technological advancements, CSL gives our customers superior results

Lifting of Sunken or Uneven Concrete

Lifting Concrete

Concrete lifting has many advantages over tear-out and replacement: the surrounding landscape is left undisturbed, the procedure usually takes only a few hours, and objects do not necessarily have to be removed from the surface of the concrete. The cost of concrete lifting is significantly lower than replacement, often at 1/3 to 1/4 the cost.

CSL offers two material choices for concrete lifting: grout injection or polyurethane foam injection. Both carry a 5 year warranty against any sinking or settling 1 inch or more.

With grout injection, a 2 inch hCalgary concrete liftingole is drilled through the concrete in several places, and a specialized grout mixture is injected, which lifts and levels the area. The corrected area can be used again several hours after the procedure.

With polyurethane foam injection, a small 3/8 inch hole is drilled through the concrete in several places, and a lightweight and very durable polyurethane foam is injected, which lifts and levels the area. The corrected area can be used again 30 minutes after the procedure.

Void Filling and Soil StabilizationSoil Stabilization

Areas where soil has settled leaving voids under concrete structures can lead to many future problems. Polyurethane or grout injection can be used for void filling as well as for stabilizing loose or unstable soil. Compaction grouting or permeation grouting techniques are used, depending on the situation.
