Serving homeowners throughout St. Louis, we use advanced methods to repair and level sidewalks quickly and efficiently, saving you the cost and hassle of full replacement.
Common Problems with Sidewalks and Walkways
Many factors contribute to uneven or damaged sidewalks, including:
- Soil Erosion & Settlement – Over time, soil beneath the concrete can erode or shift, causing slabs to sink or become uneven.
- Tree Root Growth – Expanding tree roots can push up sidewalk sections, creating hazardous raised edges.
- Freeze-Thaw Cycles – Water seeping into cracks expands when frozen, leading to further cracking and lifting.
- Heavy Loads & Wear – Excess weight from vehicles or heavy foot traffic can cause gradual deterioration.
- Poor Installation – Improper initial installation, including inadequate compacting of the soil, can lead to premature failure.
Our Sidewalk Repair & Leveling Solutions
At Cornerstone Structural Repair & Waterproofing, we use the most effective methods to repair sidewalks and walkways, ensuring long-term stability and durability. Our residential concrete repair services and solutions include:
Concrete Leveling (Polyurethane Foam Injection)
Also known as polyjacking or polyurethane foam leveling, this technique involves injecting high-density polyurethane foam beneath the sunken slab. The foam expands, raising the concrete back to its original level while stabilizing the underlying soil. Benefits include:
- Quick curing time (usable within hours)
- Cost-effective compared to full replacement
- Waterproof, preventing further soil erosion
Mudjacking (Slabjacking)
Mudjacking is another method used for lifting sunken sidewalks by injecting a slurry of cement, sand, and other materials beneath the slab. While effective, this method is not as long-lasting as polyurethane injection and can be heavier on the soil.
Crack & Joint Repair
Cracks in your sidewalk can worsen over time if not properly sealed. We use high-quality sealants to prevent water infiltration, stopping further damage caused by freeze-thaw cycles.
Resurfacing & Concrete Overlay
If your sidewalk is heavily pitted or worn but structurally sound, resurfacing may be an ideal solution. A thin, durable concrete overlay can restore a smooth finish without the cost of complete replacement.
Total Sidewalk Replacement
For sidewalks with severe structural damage or excessive deterioration, a full replacement may be necessary. Our team ensures proper site preparation, grading, and installation for long-lasting results.
