Professional Concrete Restoration in Calgary
Concrete is highly durable, but over time, ground settling, heavy vehicle loads, and Calgary's intense freeze-thaw cycles can lead to structural cracking, surface scaling, or sinking. Leaving these issues unaddressed lets water seep deeper beneath the slab, accelerating erosion and leading to costly replacements. Calgary Concrete Masters provides complete structural and cosmetic concrete repair services to restore your surfaces.
Common Calgary Concrete Issues We Repair
1. Surface Spalling & Scaling
Spalling occurs when the top layer of concrete chips and peels away, leaving a rough, dusty aggregate underneath. In Calgary, this is commonly caused by winter freeze-thaw cycles combined with road salts tracked in by vehicles. We grind down the damaged layer and apply a high-strength polymer-modified overlay to restore a smooth, durable finish.
2. Settlement & Sunken Slabs
Sunken concrete pads—often occurring next to garage openings or along sidewalks—happen when the subgrade clay soil wash away or settle. This creates dangerous tripping hazards and pooling zones. We utilize mudjacking (pressure-pumping a custom grout slurry under the slab) or poly-leveling injections to raise the concrete back to its original grade slope.
3. Structural & Shrinkage Cracks
Cracks larger than 1/8" let water seep down to the gravel sub-base, causing erosion and frost heave shifts. We route out the cracks using diamond blades, vacuum away all dust, inject high-elongation polyurea or structural epoxy resins, and sand-match the finish to blend with the surrounding slab.
Our Concrete Repair Methods
-
Polyurea Joint & Crack Injections Flexible, heavy-duty sealants that expand and contract during Calgary's extreme temperature swings without losing adhesion.
-
Polymer-Modified Resurfacing Overlays Thin-coat structural overlays that bond chemically to old concrete, providing a brand-new non-slip finish.
-
Slab Jacking & Leveling Lifting garage pads, steps, and sidewalks back to structural alignment without the cost of demolition and re-pouring.
-
Siloxane Hydrophobic Sealing We apply deep-penetrating siloxane sealers to repel road salts and water, preventing future winter spalling.
Concrete Repair Cost Estimate
Minor cracking can be repaired quickly, while structural slab leveling is priced based on injection volumes. Below are typical costs:
| Repair Service Type | Typical Cost Range | Description |
|---|---|---|
| Crack Routing & Sealing | $10.00 - $15.00 / linear foot | Cutting, cleaning, and polyurea resin injection. |
| Slab Resurfacing Overlay | $5.00 - $8.00 / square foot | Grinding old surface, polymer skim coat, broom texture. |
| Slab Leveling (Mudjacking) | $900 - $1,800 total average | Lifting sunken sidewalk slabs, stairs, or garage aprons. |
