Concrete Removal & Replacement in St. Louis is the clean, definitive solution when your driveway, patio, or slab has cracked beyond repair, settled into the clay and loess, or simply worn out after decades of freeze-thaw cycles and road salt. St. Louis sits on silty loess and clay over limestone, with karst sinkholes in parts of the region and old clay-mine fill in some neighborhoods, so concrete here doesn't just age, it settles. Whether you're dealing with a buckled alley pad in Soulard, a spalling front walk in the Central West End, a sunken rear garage slab in St. Louis Hills, or a crumbling patio in a County subdivision, we tear out the old, haul it away, and pour a fresh, properly graded replacement with a sub-base that won't fail. This is not repair or resurfacing, it's a complete do-over, and it's the right move when patching won't hold.
Why Concrete Removal and Replacement Matters in St. Louis's Demanding Climate
St. Louis winters bring real freeze-thaw cycles, snow, ice, and road de-icing salt that scales and pits driveways and walks from the city to the suburbs. Spring thunderstorms and summer heat speed concrete set times and stress old slabs. The ground itself, silty loess and clay over limestone, shifts and settles under weight, especially in older neighborhoods and near the Missouri and Meramec where soil is soft river-bottom clay. After 20, 30, or 40 years, a concrete slab doesn't just crack, it heaves, sinks, and breaks apart. Repair and resurfacing buy time, but when the damage is deep or widespread, removal and replacement is the only permanent fix.
- Freeze-thaw scaling and salt damage pit the top 2 to 3 inches, leaving surface repairs exposed to fail again next winter.
- Settlement and heaving caused by clay and loess movement create gaps, cracks, and trip hazards that widen every freeze cycle.
- Old concrete over poor or washed-out sub-bases loses bearing and cracks in spider-web patterns that no sealant or overlay can hold.
- Permitting and right-of-way compliance for sidewalks, driveway curb cuts, and alley pads require proper removal and disposal records.
Complete removal and replacement eliminates the root cause, gives you a fresh slab on a properly compacted base, and resets your warranty clock.
Key info: A driveway in Lafayette Square or Benton Park that has settled 2 inches or cracked into large chunks is a candidate for removal and replacement. The city's tight lots mean rear garage slabs and alley pads take heavy use and settle faster on clay fill. One estimate may recommend overlay, but if the base is gone or the slab is already below grade, replacement is the only code-compliant choice.

How We Execute Concrete Removal and Replacement in St. Louis
Our process starts with a walk-through to assess the slab depth, sub-base condition, soil bearing, drainage, and any underground utilities or tree roots. We then plan the removal, schedule the work to fit your schedule and the weather window, obtain any required municipal permits for right-of-way work, and execute the tear-out and haul-away in one or two days. Once the old concrete is gone, we grade the subgrade, compact a new gravel or recycled asphalt base to code, set forms, and pour the new slab with proper slope for drainage and finish of your choice, whether broom-finish, smooth trowel, or stamped.
- We remove the old concrete with a skid-steer loader or small excavator, breaking it into manageable pieces and loading it into a dump truck.
- We compact the base layer to 95% Proctor density, install new gravel or recycled base, and set up forms to the correct height and slope.
- We pour fresh concrete to your specifications, finish it to your preference, and protect it during cure with plastic sheeting and watering in hot weather.
- We remove forms after 24 to 48 hours, clean the edges, and leave a ready-to-use surface within 7 days for light foot traffic.
The result is a slab with a solid foundation, proper drainage, and no hidden voids or weak spots.
Local example: A 16 by 20 foot driveway in Webster Groves with a settled base and spalling surface takes two days to remove and replace. Day one is tear-out and haul-away, day two is base prep, forming, and pour. By day three, the homeowner can park on it. In Chesterfield, a 20 by 24 foot patio removal and replacement, including site prep and a broom finish, runs four to five days and costs more because of the larger footprint and the need to tie in to existing structures.

Concrete Removal and Replacement Methods
| Approach | Description | Best for |
|---|---|---|
| Full tear-out with skid-steer | Hydraulic breaker or bucket teeth break concrete into chunks, loaded into dump truck. Fast, efficient, minimal hand labor. | Residential driveways, patios, and garage slabs up to 500 sq ft in accessible yards. |
| Selective demo with hand labor | Manual breaking and removal using jackhammers and wheelbarrows. Slower, quieter, better for tight city lots and close neighbors. | City rowhouse alleys, front walks with stoop steps, small patios in Lafayette Square or Benton Park. |
| Concrete recycling and reuse | Broken concrete is crushed on-site or at a facility and returned as recycled aggregate base for the new slab. | Large jobs, environmentally conscious homeowners, or projects where base material cost savings offset processing fees. |
| Saw-cut removal with vacuum excavation | Concrete is cut to precise edges and removed in sections. Used when utilities or tree roots must be protected. | Slabs near gas, water, or electrical lines, or under mature oaks and maples where root systems are critical. |
Concrete Removal and Replacement Cost in St. Louis: What to Expect
Concrete Removal & Replacement in St. Louis starts at $7 per square foot and scales with slab size, sub-base condition, site access, and finish choice. A 400 square foot driveway runs roughly $2,800 to $3,200, while a 600 square foot patio or large rear slab may cost $4,200 to $5,400. The biggest cost drivers are removal and haul-away (especially if the old concrete is thick or heavily reinforced), new base material and compaction, and the finish you choose (broom-finish concrete is the baseline; stamped or decorative finishes add $2 to $5 per square foot). Site access matters too, a tight city lot or alley in downtown St. Louis may require hand labor and wheelbarrows, adding 20 to 30 percent. Soil conditions, such as clay fill or poor drainage, may require thicker base or additional grading, also pushing cost up. For large or complex jobs, an on-site estimate is essential to nail down the real price.
We always recommend getting two or three estimates to understand the range and what each contractor includes. Some quote only tear-out and haul, others include base prep and compaction, and the best proposals spell out the finished surface, warranty, and cleanup.

What to Look for When Hiring a Concrete Contractor Near Me in St. Louis
When you're ready to hire a concrete contractor for removal and replacement, start by asking for proof of general liability insurance and workers' compensation coverage. A legitimate contractor carries both on every job and can provide a certificate of insurance within 24 hours. Ask for at least three references from recent jobs similar to yours, and call them to ask about timeline, cleanliness, communication, and whether the finished product met expectations. Get multiple estimates in writing, with each one spelling out the scope, materials, timeline, and total cost so you can compare apples to apples. If your home is in a historic district or protected neighborhood, ask about permit requirements and whether the contractor has experience navigating local rules. If you're in an HOA, check the covenants for any restrictions on concrete color, texture, or setback, and confirm the contractor understands them. Finally, trust your gut: a professional contractor answers your questions clearly, shows up on time, and treats your home with respect.
