“Dustin and his team did a fantastic job on our floor. They started at 8am and didn't finish until 10pm that night. Went above and beyond to ensure the final product exceeded our expectations. One point that specifically stood out, was the clear communication from everyone with Rhino, on the process throughout the day. The entire team clearly has been through extensive customer service training. I wouldn't hesitate to recommend to my family and friends.”

Why new concrete cracks in Post Falls
A lot of the concrete in town is young. Fresh slabs shrink and settle, and then the first few winters go to work on whatever opened up.
Settling on the Prairie
New subdivisions across the Prairie sit on ground that keeps compacting after the pour. The slab settles, hairline cracks show up in year one or two, and winter water widens them. We fill those cracks with polyurea early, before freeze-thaw turns a cosmetic line into a ragged trench.
Shrinkage cracks
Every slab shrinks as it cures, and if the control joints were cut late or shallow, the crack goes wherever it wants. Common in fast-schedule production builds. We grind the random crack out, fill it flush with polyurea, and under a coating it disappears completely.
Deicer pitting
Same North Idaho winters as the rest of the county: whatever the plows spread between here and the Washington line comes home on your tires. It sits in the wet film under the car and eats the surface. We grind off the damaged paste and restore a hard, even finish.
How we repair damaged concrete
A crack tells you something, and reading it right is the difference between a fix that lasts and a patch that pops out. Settling cracks near Riverbend behave differently than shrinkage cracks in a Prairie subdivision garage. We identify the cause first, then diamond-grind, fill every crack and failed joint with polyurea, and restore the surface so it looks poured, not patched.
The Washington line is close, and our shop is closer. There is no trip charge to Post Falls or Hauser, quotes are fast, and the price we write down is the price you pay. Repaired slabs can be coated with our polyurea base and polyaspartic topcoat afterward, and repair-only work is welcome. Bring us the ugly floor. That is the job.
- Polyurea crack fill stays flexible through freeze-thaw cycles
- Diamond grinding, not acid etching, for a real mechanical bond
- Repair only, or repair plus a coating that seals the fix in
- Fixed written price after a free on-site assessment

Our concrete repair process in Post Falls
The same process on every slab we touch, whether it is next door or across town.
- 01
Diagnose the cause
Cracks, spalling, and pitting all have a reason: water, deicer, settling, or a bad original pour. We find it first so the repair holds.
- 02
Grind and fill
We diamond-grind the damaged area, fill cracks and joints with polyurea that cures fast and stays flexible through freeze-thaw, and repair spalls with the method that fits them.
- 03
Blend or coat
Repair-only slabs get the surface blended back in. Or have us seal the fix under a polyaspartic coating that protects the repaired surface.
Concrete repair questions in Post Falls
My house is only a few years old. Why is the garage slab cracked already?
Settling. New subdivisions can sit on ground that keeps compacting for years after construction, and the slab moves with it. Hairline settling cracks are normal and fixable. We grind them open, fill them with polyurea that flexes with further movement, and the floor stops showing it. Catch them early and they never get ugly.
Repair or replace: how do I know?
Tearing out a slab is a much bigger job than restoring one, so replacement is the last resort, not the first quote. If your concrete is cracked, pitted, or flaking but still sitting flat, we can save it. If sections have dropped or heaved badly, we will tell you at the free measure, no charge, no pressure.
How long does a concrete repair job take?
Most residential repair work is a single day: grind in the morning, fill and finish by afternoon. Adding a full flake or silica coating over the repaired slab usually keeps it a one-day job too. Big shop floors can run longer, and we tell you exactly what to expect in the written quote.
What will it cost me?
Depends on crack footage, how much surface needs grinding, and whether you want a coating over the repair. We do not price by phone photos. We come out, measure, and write a fixed number with no surprise charges. The visit is free, and being minutes away, we can usually schedule it fast. Call 208-500-1043.
Can you repair and coat the floor in the same trip?
That is the standard play. The repair prep and the coating prep are the same diamond grind, so combining them saves you money and a second appointment. We fill cracks and joints with polyurea, lay the polyurea base coat, broadcast flake to refusal, and seal it with the polyaspartic topcoat. Most garages: one day.

“Karl and his team did a beautiful job on my garage floor. They fixed a crack, sanded the floor. It looks amazing now. They also fixed a crack in my pad outside the garage. I had the pad coated using sealer, sand, and a Sherman Williams tint. My pad looks so nice. They are a hard working, professional team who pay attention to details. The end products were well done. I am very happy with their work.”
