Concrete Floor Repair In Cambridge, Ontario

Salt And Freeze-Thaw Damage The Surface

Salt damage is where a lot of concrete floor repair begins. Brine soaks into garage and dock slabs, then freezes and thaws through the winter. The surface flakes and pits, and the damage spreads every year.

The scaled crust gets ground away and fresh resin mortar fills it back to level. Then the floor can take a coating that keeps the salt out.

Broken Joints And Cracks

Forklifts and carts hammer the edges of slab joints until they chip and break. The broken edges get saw-cut out and the joint is rebuilt with a firm filler.

Cracks are routed clean, then filled with a flexible or rigid product depending on whether the crack still moves. Large cracks in old basements in East Galt and Preston often need this step before any coating.

Grinding Old Paint And Coatings

Many older floors carry layers of paint, failed kits or tile glue. Concrete floor repair includes grinding all of that away with diamond tooling. That leaves clean, open concrete for the next coating.

Concrete Floor Repair Before A Coating

Patching is usually bundled into a coating job. A garage floor coating, basement floor coating or warehouse floor coating quote will list any repairs the slab needs.

Chipped Dock Edges And Garage Steps

Dock plates, curbs and the step from the garage into the house take hard knocks, and their edges chip away. Concrete floor repair rebuilds those edges with a strong mortar shaped to match the original line.

Low Spots And Uneven Slabs

Water pools in low spots and freezes there in winter. We fill shallow dips with a self-levelling or trowelled mortar so water runs to the drain or the door. Lips at cracks are ground flat. Concrete floor repair like this makes the floor safer to walk on and lets the next coating go down at an even thickness.
