What Is Concrete Crack & Hole Repair? Suitability and Common Questions

Crack repair is the process of routing a crack — opening it to sound material — cleaning it, and filling it with a repair material matched to the crack type. A static crack gets a rigid filler; a moving joint or a crack that flexes gets a flexible material that can move with the slab. The repair is leveled to the surrounding surface so the coating bridges a smooth, sound plane. See our diamond concrete preparation and polishing for the prep that pairs with the repair.

Hole and spall repair is the process of cleaning out a spalled area or a hole, filling it with a patch material, and leveling it to the slab. A spall is a surface defect where the concrete has chipped or flaked; a hole is a deeper defect. Both are repaired so the coating has a continuous surface to bond to — because a coating that bridges a hole is a coating that fails at the hole.

The repair is the foundation of the coating. A coating is only as durable as the slab it bonds to, and a crack or a hole is a discontinuity in the slab that the coating can't bridge indefinitely. The repair stabilizes the defect so the coating has a stable substrate, and it's the step that makes the difference between a floor that lasts and one that fails at the first crack.

Crack and hole repair is suitable for any homeowner or business whose slab has defects before a coating. A garage slab with cracks, a warehouse floor with spalls, a driveway with holes — each one needs the repair before the coating, because the coating doesn't fix the defect, it covers it. The repair is the preparation that makes the coating bond to a sound surface.

The repair also suits the homeowner whose slab has a crack that's been there for years. A static crack that hasn't moved can be repaired and coated; a moving crack that's growing needs a flexible repair and a coating system that can accommodate the movement. We assess the crack type during the estimate and match the repair to the crack — because the wrong repair on a moving crack is a repair that fails.

Crack and hole repair also suits the property owner who wants to address the slab before it gets worse. A crack that's ignored can grow; a spall that's ignored can spread. The repair stabilizes the defect and the coating protects the slab — and together, they're the maintenance that keeps a concrete floor sound for years.

The most common question is whether a crack will come back through the coating. A properly repaired static crack, with the right filler and a sound substrate, won't — the repair stabilizes the crack and the coating bridges the smooth surface. A moving crack that isn't repaired with a flexible material will telegraph through the coating, which is why we match the repair to the crack type.

Another frequent question is whether every crack needs repair. Not every crack affects the coating — a hairline crack in a stable slab may not need repair, while a wider crack or a moving crack does. We assess each crack during the estimate and tell you which ones need repair and which don't, because over-repairing is a cost and under-repairing is a failure.

Homeowners also ask whether the repair will be visible through the coating. A solid color coating may show the repair line; a flake finish hides it. We help you choose a finish that works with the repair — because a repair that's visible isn't a failure, but a finish that hides it is often the choice when the slab has a lot of repairs.

The repair material is matched to the crack type. A static crack gets a rigid filler that bonds the crack closed; a moving joint or a flexing crack gets a flexible material that can move with the slab. The wrong material on the wrong crack is a repair that fails — a rigid filler in a moving crack will crack again, and a flexible material in a static crack is overkill. We assess the crack type and match the repair.

The finish is the second choice. A solid color coating may show the repair line; a flake finish hides it. We help you choose a finish that works with the repair and the slab — because a slab with a lot of repairs often benefits from a flake finish that hides them, while a slab with one or two repairs can take a solid color.

We come to your property to assess the slab, identify every crack, spall, and hole, and determine what each defect needs. The estimate includes the repair scope, the repair materials, and the preparation — so the cost reflects the actual defects.
