Concrete Floor Prep & Repair Des Moines

Every good floor coating starts with a sound slab. Colin Coatings repairs cracks, pitting, spalling, control joints, low spots, and moisture problems in concrete floors across the Des Moines metro, as the first step of a coating or as a stand-alone service. With 20+ years of pouring and finishing concrete in Central Iowa, we fix the concrete problem instead of covering it.

Repairs We Do

Crack Repair

Cracks are chased with a diamond blade, cleaned, and filled with a flexible polyurea or rigid epoxy depending on whether the crack is moving. Ground flush.

Pitting & Spalling Repair

Salt-damaged and scaled surfaces are ground, then filled with a fast-set polymer patch that bonds to the slab and accepts a coating.

Control Joint Fill

Semi-rigid polyurea joint filler for garages, shops, and warehouses so wheels don't chip the joint edges and salt can't get below the slab.

Leveling & Resurfacing

Self-leveling underlayment and epoxy mortar for low spots, birdbaths, and rough slabs.

Moisture Mitigation

Calcium-chloride and in-slab RH testing; epoxy moisture-vapor barriers rated to 25 lbs / 100% RH for basements and new slabs.

Diamond Grinding & Surface Prep

CSP 2–3 mechanical profiling with dust collection, for our coatings or for flooring installers who need a prepped slab.

Slab Replacement

When a floor is heaving, badly sunken, or structurally failed, we replace it through Colin Concrete Des Moines.

Why Iowa Concrete Floors Fail

Iowa's 42-inch frost depth moves slabs every winter, opening cracks and heaving edges. Magnesium-chloride road salt dissolves the cement paste on the surface and causes pitting and scaling. Saturated clay under the slab drives moisture upward all spring. Any coating installed over these problems without fixing them first will fail in a couple of seasons, which is why repair is a line item on every one of our estimates.

Questions

Can a cracked garage floor be coated?
Almost always. Cracks are repaired and ground flush, and a full-flake coating hides the repair completely. Heaving or badly sunken slabs may need replacement first.
Do you fix pitting from road salt?
Yes. Pits are filled with a polymer patch, ground flush, and coated. A coating then prevents further salt damage.
What is moisture mitigation?
A specialized epoxy primer that blocks vapor from the slab so a coating (or flooring) doesn't blister. Required when moisture tests come in over the coating's limit, common in Des Moines basements and new construction.
Do you do repair without a coating?
Yes. Crack repair, joint fill, grinding, and leveling are available on their own, including prep for other flooring contractors.
