Concrete Floor Repair For Cracks And Spalling
Garage and basement cracks get a rigid epoxy filler when they have stopped moving, or a flexible polyurea when they still shift with the seasons. Scaled spots, where frost has popped the surface loose, are cut back to firm concrete and rebuilt with repair mortar.
The apron by the overhead door soaks up the most salt, so that strip usually needs the most concrete floor repair.
Sump Pit And Backwater Valve Patches
Flood protection work is common in Kingston, and every sump or backwater valve install leaves a trench in the basement floor. The new concrete shrinks as it cures, and a hairline gap often opens around the edge.
We fill that gap, sand the patch level with the old floor and wait for it to dry. That keeps the patch from showing through the finished basement epoxy flooring.
Removing Old Coatings That Have Failed
Lifting paint and failed kit coatings must come off entirely. A new coat over them only loads more weight onto a bond that is already breaking. We grind down to bare concrete, fix what turns up and then build the new floor.
A stand-alone concrete floor repair is priced per job. When it is part of a coating, it shows as its own line on the quote.
Concrete Floor Repair For Sunken And Uneven Slabs
Garage floors that have settled toward the door and basement floors with low spots both hold puddles. Concrete floor repair fixes that before the coating. We grind down raised edges, then fill the dips with a self-levelling underlayment or an epoxy mortar so water runs where it should.
A slab that has heaved along a crack gets ground flat across the joint, so a car tire or a cart wheel rolls over it smoothly.
Commercial Slabs Break Down At The Joints
Forklift wheels hammer the edges of saw-cut joints until they chip and widen. Those joints get cleaned out and refilled with a semi-rigid joint filler that supports the wheel. Old anchor holes from removed racking, broken trench drain edges and damaged dock plates are all rebuilt as part of commercial concrete floor repair.
Because serviced industrial land in Kingston is scarce, many businesses renovate older buildings, and those floors usually need this work first.
