Toronto Straight answers ## Repair & Specialty Concrete Questions We Get Asked ### help Should I repair or replace my concrete driveway? expand\_more Often you can repair. About half the driveways called in for replacement can be repaired at roughly 40 percent of the cost through crack repair, lifting, or resurfacing. If the slab is heaved, badly spalled, or sitting on a failed base, replacement is the better long-term choice. We assess and tell you honestly. ### help How much does concrete lifting cost vs replacement? expand\_more Lifting a sunken slab costs $6 to $12 per sq ft, often a fraction of full replacement. When the concrete itself is sound and only the base has settled, lifting is the smart choice. If the slab is cracked through or crumbling, replacement is better value long term. ### help What is the difference between mudjacking and polyurethane foam lifting? expand\_more Mudjacking pumps a cement slurry under the slab to raise it, while polyurethane foam injects a lightweight expanding foam. Foam is lighter, cures in minutes, and resists re-settling in Toronto clay soil, where heavy slurry can sink again. We recommend foam for most GTA jobs. ### help How long does concrete last? expand\_more Well-installed, sealed concrete lasts 25 to 40 years or more in the GTA. Freeze-thaw cycles and road salt are the main enemies; regular sealing and prompt crack repair are what stretch a slab to the top of that range. ### help What is your warranty on concrete repair? expand\_more Every installation, including repairs, carries our 2-year workmanship warranty. We are licensed, WSIB-insured, and carry $2M general liability, so the work is backed and covered. ### Still have questions? We answer the phone 24/7 and reply to quote requests inside two hours.
