Question 1

What exactly is poly-level concrete leveling?

Accepted Answer

Poly-level is a modern concrete repair method that uses expanding polyurethane foam to lift and support sunken slabs. We drill small, 5/8-inch holes into the concrete and inject the foam into the void underneath. This material expands, filling the space, stabilizing the soil, and precisely raising the slab back to its original height. This technique is much faster, cleaner, and more durable than traditional mudjacking, which uses a heavy cement slurry. In our experience, this form of concrete leveling provides a superior, long-lasting result by creating a stable, waterproof base that resists future settlement, making it ideal for the local climate.

Question 2

How long does the lifting process typically take?

Accepted Answer

One of the major advantages of our process is its speed. Most residential concrete leveling projects, such as a sinking driveway, walkway, or patio, are completed within a few hours. A standard job often takes between 2 to 4 hours from arrival to cleanup. The polyurethane foam cures very quickly. You can walk on the repaired surface within 30 minutes of project completion, and you can drive a vehicle on it within 4 to 6 hours. This minimal downtime means less disruption to your daily routine compared to the days or weeks required for concrete replacement.

Question 3

Is concrete leveling a permanent fix for my sinking slab?

Accepted Answer

Yes, when done correctly with high-quality materials, concrete leveling is considered a permanent, long-term solution. The high-density polyurethane foam we use is an inert, stable, and waterproof polymer. It will not break down, rot, or wash away underground. By filling the voids and stabilizing the soil base, it addresses the root cause of the settlement. The foam creates a solid foundation that prevents the slab from sinking again. This makes the concrete leveling repair incredibly durable and able to withstand Oshawa's demanding freeze-thaw cycles for many years to come.

Question 4

What causes concrete slabs to sink in the Oshawa area?

Accepted Answer

In our 14 years of experience here, the primary cause of sinking concrete is soil instability beneath the slab. This is often due to poor soil compaction when the home was built, or soil erosion from water. Oshawa's distinct freeze-thaw cycles are a major contributor; water freezes and expands the soil, then thaws and leaves a void, causing the slab to settle. Downspouts discharging water too close to a slab can also wash away the supporting soil. We diagnose the specific cause on your property to ensure our concrete leveling solution is effective and permanent.

Question 5

How much can I expect to pay for concrete repair?

Accepted Answer

The cost for professional concrete leveling is typically 50-70% less than the cost of replacement. Pricing in Oshawa usually falls between $8 and $25 per square foot. The final cost depends on the size of the area, the depth of the void underneath the slab that needs filling, and overall site accessibility. A small, straightforward repair on a sidewalk might cost a few hundred dollars, while a larger driveway or patio could be a few thousand. We provide a firm, detailed quote after an on-site inspection so you know the exact cost before we begin any work on your property.

Question 6

Is poly-level foam better than traditional mudjacking?

Accepted Answer

Yes, in almost every aspect, poly-level is a superior method. The injection holes are much smaller (5/8-inch vs. 2 inches), making the repair less noticeable. The polyurethane foam is extremely lightweight, so it doesn't add extra weight to already unstable soil, unlike the heavy mudjacking slurry. The foam is also waterproof and won't erode, providing a more permanent solution. Finally, the curing time is much faster. We believe poly-level concrete leveling offers a cleaner, more durable, and more precise result for our clients' properties.

Question 7

Can any sunken concrete slab be lifted?

Accepted Answer

Most sunken concrete slabs can be successfully lifted, provided the concrete itself is in relatively good condition. If a slab is severely cracked into many small pieces, crumbled, or has a shattered surface, it may not be a good candidate for concrete leveling. In those situations, the slab may not have enough structural integrity to be lifted without breaking apart further. During our initial assessment, we will determine if your slab can be saved. If replacement is the better option, we can discuss our concrete driveway building or demolition services as an alternative solution.

Question 8

Will the polyurethane foam harm my lawn or garden beds?

Accepted Answer

No, the materials we use are environmentally safe and will not harm your landscaping. The two-part polyurethane foam is injected directly beneath the concrete slab. It expands and cures quickly, becoming a completely inert, stable, and non-toxic solid. Once cured, it does not leach any chemicals into the surrounding soil or groundwater. Our process is self-contained below the slab, ensuring that your lawn, plants, and pets are safe. This makes our concrete leveling service an eco-conscious choice for homeowners.
