Concrete Repair & Surface Restoration

Before we coat, we fix. Cracks, spalling, pitting, edge damage — we diagnose and repair your concrete substrate so the finished coating bonds properly and lasts for decades, not months. Proper prep is the foundation of every job we do.

Why Surface Prep Is the Most Important Step

The number one reason floor coatings fail isn't the product — it's the preparation. A coating applied over a weak, contaminated, or damaged surface will delaminate regardless of how good the product is.

We diamond-grind every floor and repair every crack and damaged area before applying any coating. This isn't optional for us — it's the standard that defines the difference between a 2-year floor and a 20-year floor.

  • Crack injection and filling — hairline to wide-gap
  • Spall and pop-out repair — restored to level surface
  • Edge and threshold rebuilding — garage door thresholds, perimeter damage
  • Diamond grinding and surface profiling — proper CSP for coating adhesion
  • Old coating and paint removal — full mechanical strip

Types of Concrete Damage We Repair

Every damage type has a right repair method. We match the method to the cause.

Shrinkage Cracks

Hairline and narrow cracks formed during initial concrete curing. Filled with semi-rigid polyurea filler for a flexible, permanent repair that moves with the slab.

Wide-Gap & Structural Cracks

Cracks wider than 1/8" or caused by settlement and movement. Ground out, filled with structural polyurea or cementitious mortar, and monitored for activity before coating.

Spalling & Surface Pop-Outs

Caused by freeze-thaw cycles, deicing salts, or weak surface concrete. Profiled with a grinder or scarifier and patched with cementitious repair mortar feathered to the surrounding surface.

Edge & Threshold Damage

Garage door thresholds and slab perimeters take significant abuse. We rebuild damaged edges to original profile before the coating system is applied.

Pitting & Surface Deterioration

Aggregate exposure, pitting, and surface laitance are removed via diamond grinding to reveal fresh, sound concrete ready for coating adhesion.

Existing Coating Removal

Old paint, epoxy, or sealer must be fully removed before a new polyaspartic system is applied. We use mechanical grinding to strip existing coatings completely.

Our Approach to Concrete Repair

We fix before we coat. Every time. No exceptions.

We Fix Before We Coat

We don't skip the hard part. Every crack, spall, and damaged edge is addressed before any coating goes down. That prep investment is what makes our floors last decades.

Repair-Only Jobs Welcome

You don't have to coat to get repairs done. If your concrete needs restoration without a full coating, we can handle that as a standalone service for driveways, garage floors, and commercial slabs.

Right Materials for the Job

We use professional-grade repair mortars, polyurea crack injection systems, and grinding equipment — not big-box fillers. The repair material is matched to the damage type and the downstream coating system.

Our Concrete Repair Process

Honest assessment, right repair method, proper surface profile — in that order.

1

Damage Assessment

We inspect the full slab — cracks mapped, spalls measured, edges evaluated. We identify the cause of damage (settlement, freeze-thaw, impact, shrinkage) so the repair method addresses the root cause.

2

Repair & Restoration

Cracks are ground out, injected, and filled. Spalls and pop-outs are profiled and patched with repair mortar. Damaged edges and thresholds are rebuilt to original profile.

3

Surface Profile

The full slab is diamond-ground to achieve the correct surface profile (CSP) for the intended coating system. This step removes laitance, opens the pores, and ensures maximum adhesion.

Concrete Repair — Before, During & After

Every repair job starts with an honest assessment and ends with a surface ready for decades of use.

Concrete Repair Questions

Common questions from homeowners and business owners about concrete repair in Coeur d'Alene and Spokane.

Can you repair concrete cracks before coating?

Yes — in fact, this is required. We repair all cracks before applying any coating system. Crack repair methods vary by crack type: shrinkage cracks are filled with semi-rigid polyurea filler, while moving/structural cracks may require flexible joint treatment.

Can badly damaged concrete be saved, or does it need to be replaced?

Most damaged concrete can be restored to a coatable condition without replacement. The threshold is structural integrity — if the slab has heaved significantly, is actively sinking, or has deep structural failure, replacement may be warranted. We'll give you an honest assessment during your free estimate.

How do you fix a garage floor that's flaking or spalling?

Spalling (surface delamination) is addressed by profiling the damaged area with a grinder or scarifier, then filling with a cementitious repair mortar. The repair is feathered to match the surrounding surface level and allowed to cure before coating.

Do you offer concrete repair without a full floor coating?

Yes. Concrete repair is available as a standalone service for driveways, garage floors, basement slabs, and commercial floors. We can assess the damage and provide a repair-only quote at no charge.
