What is Mudjacking and How Does it Work?

Poly-mor Mudjacking, concrete slab lifting

Mudjacking, also known as slabjacking or concrete leveling, is a process used to level and stabilize concrete slabs that have settled or sunk due to such factors as soil erosion. The process involves drilling holes into the concrete slab and pumping a mixture of soil and cement concrete filler, called grout, under the slab to raise it to the desired level.

Mudjacking is typically a more cost-effective alternative to replacing the concrete slab and can be used on concrete sidewalks, driveways, patios, and other surfaces.

Why might I need mudjacking?                 

You might need mudjacking if you’ve noticed that your concrete slab has settled or sunk. This can happen for a variety of reasons, including:

Soil erosion: The soil beneath the slab can erode over time, causing the slab to sink. This sometimes requires concrete leak sealing or soil stabilization.

Improper soil compaction: If the soil wasn’t properly compacted before the slab was poured, it can settle over time, causing the slab to sink.

Tree roots: If there are large trees near the slab, their roots can grow under the slab and cause it to crack, heave, or sink.

Water damage: Excess water under the slab can cause the soil to wash away, resulting in the slab sinking.

Freeze-thaw cycles: In areas with cold winters, water can seep into the slab, then freeze and expand, causing the slab to crack and sink.

These issues can cause uneven surfaces, cracks, trip hazards, and general damage to the slab or anything the slab might be supporting. Mudjacking can level out these surfaces and help stabilize the slab, restoring safety and functionality to the area. It can also prevent the slab from sinking further and causing more serious damage with time.

How much does mudjacking cost?            

The cost of mudjacking can vary depending on a number of factors, such as the size and condition of the slab, the amount of material needed to level it, and the location of the property. On average, you can expect mudjacking to cost between $3 and $7 per square foot in the cities Poly-Mor Canada Inc. offers service in – Edmonton, Calgary, Winnipeg, and Vancouver.

Mudjacking is typically significantly less expensive than replacing the entire affected slab, making it a great choice for most types of sunken concrete repair, some foundation repair, and soil stabilisation.

What are the benefits of mudjacking?                  

Mudjacking offers numerous benefits, including:

Cost-effectiveness: Mudjacking is generally less expensive than replacing a concrete slab, making it a cost-effective solution for concrete filler, concrete lifting and/or levelling, and many types of concrete repair.

Quick and efficient: Mudjacking is a relatively quick process that can be completed in as little as a few hours, depending on the size of the slab and complexity of repairs needed.

Minimal disruption: Mudjacking requires only small holes to be drilled into the slab, so there is minimal disruption to the surface.

Versatile: Mudjacking can be used on a variety of concrete surfaces, including sidewalks, driveways, patios, foundation repair, and more.

Long-lasting: A properly mudjacked slab is not a band-aid solution; it can last for many, many years with proper maintenance.

Better Drainage: Since the grout injection raises the slab, it also helps assist in better drainage to the affected area as water will no longer pool on the slab.

Improves Curb Appeal: A leveled slab can improve the overall appearance of the property, increasing curb appeal and property value.

Better Accessibility: A level slab makes it easier for people with disabilities or mobility issues to access the property.

Safety: Uneven surfaces can be hazardous; mudjacking helps create a level surface area for increased safety.

How long does mudjacking take?              

The time it takes to complete a mudjacking project can vary depending on the size of the slab and the condition of the soil beneath it. However, mudjacking is a relatively quick process that can be completed in as little time as a few hours, depending on the size of the slab.

A small driveway or patio can take as little as 2-3 hours to complete, while larger projects such as a commercial parking lot or a large driveway can take a full day or more.

How do I maintain an area that has been mudjacked?  

To maintain an area that has been mudjacked, it is important to keep the following things in mind:

Allow the slab to settle: Once the mudjacking process is complete, the slab needs time to settle and cure. Avoid parking on the slab or placing heavy objects on it for 24 to 48 hours after the mudjacking is done.

Watering: Water the slab for the first few days after mudjacking. This will help the grout to cure and set properly.

Avoid heavy loads: Avoid placing heavy loads on the slab for at least a week after mudjacking.

Keep an eye on the slab: Regularly check the slab for any signs of settling or sinking. If you notice any problems, contact the contractor who performed the mudjacking.

Keep the slab clean: Keep the slab clean by sweeping or hosing down any debris.

Seal the slab: Seal the slab with a concrete sealer to protect it from moisture and weathering.

Keep trees trimmed: Keep trees near the slab trimmed to prevent roots from growing under the slab and causing it to settle again.

Regularly inspecting and maintaining the slab will ensure that it stays level and stable for many years. If you notice any issues, it’s best to address them promptly to prevent further damage. For more information, visit: https://www.poly-mor.ca/
