Denver Metro Concrete Repair
Lifting & leveling Denver metro concrete
Crack injection, resurfacing, and polyurethane foam lifting for driveways, sidewalks, patios, and garage slabs across Denver, Aurora, Lakewood, and the surrounding metro — engineered for freeze-thaw cycling, de-icing salt, and the expansive clay underneath nearly every subdivision on the Front Range.

The Denver Metro Problem
Three mechanisms attack metro Denver concrete at once
Concrete flatwork across Denver, Aurora, and the surrounding suburbs doesn't fail the way it does in milder climates. Around 149 freeze-thaw cycles a year push water in and out of every micro-crack, and each cycle of ice expands roughly 9% inside that crack, prying it wider. Layered on top of that is Pierre Shale and bentonite/montmorillonite clay — a soil that swells and shrinks with the seasons under most Denver-metro lots, moving driveways, walks, and patios 2 to 6 documented inches a year even when the house next to them sits rock solid on drilled piers.
Dense Denver-metro subdivisions make the problem more visible, not less — more concrete flatwork gets packed onto the same active clay belt per lot than in lower-density areas, so cracking and heave complaints cluster block by block.
- Freeze-thaw cycling: ice expands roughly 9% inside existing cracks, widening them every winter
- De-icing salt: magnesium chloride accelerates scaling and drives rebar corrosion
- Expansive clay soil: 2–6 inches of documented seasonal ground movement under flatwork
- Dense subdivisions concentrate the damage — most real jobs involve more than one cause

Know Your Options
Polyurethane foam vs mudjacking vs replacement
What we recommend
Polyurethane Foam
- $5–$25 / sq ft
- 15-minute cure
- 5/8" holes
- ~2 lb/cu ft — no soil reload
- Waterproof, effectively permanent
The traditional way
Mudjacking
- $3–$6 / sq ft
- 1–3 day cure
- 1–2" holes
- 100+ lb/cu ft on active clay
- Commonly needs redoing in 5–10 years
Last resort
Replacement
- Multiple times the cost of repair
- Days of demo + cure
- Full tear-out and re-pour
- Finish never matches
- Re-settles on the same active clay
Every Denver Winter
De-icing salt does more damage than most homeowners realize
Metro-area streets, driveways, and sidewalks get hit with magnesium chloride (MgCl2) and calcium chloride (CaCl2) de-icers all winter long. MgCl2 can be up to 10 times more corrosive to mild-steel rebar than CaCl2, and both accelerate the freeze-thaw scaling already working on the surface. We catch it before pitted scaling turns into structural spalling.
Spalling & Scaling RepairEngineered Solutions
Every repair, across the Denver metro
From a single hairline crack to a full commercial parking lot — if it's cracked, sunken, or salt-damaged, we diagnose the cause and fix it.
Precision Results
Diagnosed first, repaired to grade, documented in writing
Every job starts by identifying which of the metro area's damage mechanisms is at work, maps the repair with levels before we drill or patch, and verifies the finished result against the surrounding slab. The goal isn't a cosmetic patch — it's stopping the cycle that caused the damage in the first place, on ground that keeps moving year after year.
- Cause diagnosis before any repair method is recommended
- Elevation mapping and controlled, monitored lifts
- Joint sealing and drainage correction on every job
- Before/after documentation in writing
Commercial, HOA & municipal: a 1/4-inch edge is legal exposure
ADA standards flag any vertical change of 1/4 inch or more as a trip hazard. Denver's 2022 Ordinance 307 shifted construction and maintenance of public sidewalks to the City of Denver, funded through a property-owner Sidewalk Enterprise fee — but private walks, driveway aprons, patios, and parking-lot flatwork stay the property owner's responsibility either way. We run survey-and-repair programs with dated correction logs that close the exposure before anyone gets hurt.

Straight Answers
What Denver metro asks before the drill comes out
Costs, methods, freeze-thaw, clay soil, Ordinance 307 — the full FAQ hub covers it all.
Browse All FAQsMost Denver-area jobs run from a couple hundred dollars for a single crack or small patch up to several thousand for resurfacing or lifting a full driveway or patio slab. Cost depends on square footage, the repair method, and how much the underlying clay has already moved. We price on-site after an inspection, not off a phone description.
Denver-metro homes are almost always built on drilled piers that anchor down past the active bentonite clay layer, so the house itself stays stable. Driveways, sidewalks, patios, and garage slabs typically aren't on piers — they sit directly on the clay, so they heave and crack even while the house next to them looks untouched.
Mudjacking pumps a heavy cement slurry through 1-2 inch holes and needs a day or more to cure. Polyurethane foam injects through dime-sized holes and cures in about 15 minutes. On Denver's shifting clay, foam's much lighter weight matters — it lifts the slab without adding the heavy load that restarts settling.
It depends which slab. Denver's 2022 Ordinance 307 shifted public sidewalk construction and repair to the city, funded through a Sidewalk Enterprise fee on property owners. Private walks, driveway aprons, and patios are still the homeowner's or business owner's responsibility to maintain either way.
