Concrete Repair Services in the Twin Cities
That crack in your driveway didn't show up overnight. Neither did the spalling on your garage floor or the trip hazard where your sidewalk sections separated. Minnesota's freeze-thaw cycles, road salt, and clay soils push concrete hard — and patch jobs from the hardware store won't cut it. ATR Concrete Technologies has spent 30 years repairing residential concrete across Minneapolis, St. Paul, and the metro using our chemistry-first Clean Slate Process.

The Clean Slate Repair Process
Five steps, dust-controlled. Here's how we restore your concrete from assessment to sealed finish.
Assessment
We inspect every crack, joint, and surface to map the full scope of damage and recommend the right repair strategy.
Chemical Prep
Surfaces are chemically cleaned and profiled — eliminating airborne silica dust caused by traditional grinding. Safe for occupied homes and facilities.
Crack Fill
Cracks are routed and filled with flexible, high-strength materials engineered to move with Minnesota's temperature swings.
Surface Restoration
Spalled areas are rebuilt and the full surface is leveled, creating a uniform substrate ready for finishing.
Cure & Seal
A penetrating sealer locks in the repair and protects against future moisture, salt, and freeze-thaw damage.
Maintenance Tips
A proper repair can last decades with the right care. Follow these guidelines to protect your investment and maximize the life of your concrete.
Seal Every 2–3 Years
A quality penetrating sealer is the single best defense against Minnesota winters. We recommend resealing every two to three years.
Routine Cleaning
Remove dirt, leaves, and standing water regularly. A pressure washer on a low setting keeps surfaces clean without damaging the seal.
Winter Care
Use sand or kitty litter instead of rock salt. If you must use deicer, choose calcium-magnesium acetate — it's far gentler on concrete.
Joint Monitoring
Check expansion and control joints each spring. Cracked or missing joint filler lets water in, which accelerates freeze-thaw damage.

Common Questions About Concrete Repair
If the slab is structurally sound — no major settling, heaving, or widespread deterioration — repair is almost always the better choice. It costs 50–70% less than replacement and can be completed in a day. We will tell you honestly if your slab is beyond repair.
The primary culprit is our freeze-thaw cycle. Water seeps into pores and micro-cracks, freezes, expands, and widens the damage over hundreds of cycles per winter. Road salt accelerates this by increasing the number of freeze-thaw events. Clay soils that expand and contract also contribute to settlement cracking.
Most residential repairs — a driveway, garage floor, or patio — are completed in a single day. Larger projects or multi-area repairs may take two days. You can typically walk on the surface within 24 hours and drive on it within 48–72 hours.
We custom-tint repair materials to blend with your existing slab. While an exact color match on aged concrete is difficult to guarantee, our restorations create a uniform, attractive appearance that improves significantly over the original damage.
Our Clean Slate Process uses chemical preparation instead of mechanical grinding. Traditional grinding creates clouds of crystalline silica dust — a known carcinogen. Our chemistry-first method eliminates airborne silica dust from surface prep, making it safe for occupied homes and facilities. The only time any dust may be present is during bag mixing — and in most cases, that's done outside the building.
We stand behind every repair with a written warranty. Specific terms depend on the scope of work and materials used. During your free assessment, we will outline the warranty in detail so there are no surprises.
