Concrete Crack & Spall Repair in Sarnia
Lake Huron and Lake Erie weather, humid summers, salt-heavy winters and a large manufacturing and farm base make durable, easy-clean floors a practical choice here. That is why so many Sarnia slabs we see, from older downtown homes, family neighbourhoods and lakeside homes to the floors of the petrochemical and refining plants of Chemical Valley, have cracks, spalling or pitting that needs repair before anything else.
Every Sarnia repair is matched to the damage. Moving cracks get flexible filler, spalls are rebuilt from sound concrete, worn joints are cleaned and refilled, and lips are ground level, so the finish that goes on top has a solid base.

The system
Concrete Repair: The Foundation of Every Finish
A flawless finish starts with a sound slab. Cracks, spalls, pitting, popouts and failed joints do not disappear under a coating; they telegraph through it or break it apart. We repair the concrete properly before any epoxy, polish or sealer goes down, and we also repair floors that simply need to be safe and level again.
Cracks are routed out and filled with rigid epoxy or flexible polyurea fillers depending on whether they are still moving. Spalled and pitted areas are cleaned back to sound concrete and rebuilt with repair mortars. Worn control joints in warehouses are cleaned out and refilled so forklift wheels stop chipping the edges. Grinding takes down lips and trip hazards.

Questions
Concrete Crack & Spall Repair in Sarnia: FAQs
How do I get a concrete crack & spall repair quote in Sarnia?+

Can you fix cracks in my garage floor?+
Yes. Most garage cracks are shrinkage or freeze-thaw cracks that we route out and fill before coating. Wide or uneven cracks that are still moving get a flexible filler, and we will tell you if a crack looks structural.
What causes spalling?+
Road salt, freeze-thaw cycles and water working into the surface are the usual causes in Ontario garages and parking areas. The weakened surface flakes away. We cut back to sound concrete and rebuild it before coating, which also protects it from further salt damage.
Will the repairs show?+
Under an opaque epoxy or flake system, properly prepared repairs are hidden. On polished or sealed concrete the repairs remain visible, because it is a natural finish.
Do you repair warehouse joints?+
Yes. Damaged control joints are cleaned out and refilled with a semi-rigid joint filler, which supports the edges and makes forklift traffic smoother and quieter.
Do you offer concrete crack & spall repair across Sarnia?+
Yes. We work throughout Sarnia, including Downtown Sarnia, North End, South End, Bright's Grove and Point Edward, and in nearby Chatham, Windsor, London, St. Thomas and Stratford.
