Frequently Asked Questions
Here are the most common questions people ask us before starting a concrete raising project. If you don’t see your question here, feel free to call or text us — we’re always happy to help!
Concrete Settlement & Causes
Why does concrete sink?
Concrete sinks when the soil underneath becomes weak or uneven. In North Texas, the biggest causes are shrinking clay soil, erosion from rain, poor compaction when the concrete was poured, plumbing leaks, and heavy traffic vibration. When soil moves, gaps form under the slab and the concrete settles.
What areas are most likely to sink?
Driveways, sidewalks, patios, garage floors, pool decks, porches, and steps are the most common. Commercial properties often see settlement under parking slabs, entries, warehouse floors, and loading docks.
Can sinking concrete get worse over time?
Yes — and usually faster than people expect. Once soil movement begins, slabs can keep sinking, cracking, shifting, and creating safety hazards. Waiting often makes the repair more expensive.
Can you lift concrete that is cracked?
Yes. Hairline and moderate cracks are normal and can be lifted. If the slab is shattered into multiple pieces or missing large chunks, replacement may be the better option. We will always be honest about which solution makes sense.
Polyurethane Foam Lifting Process
How does polyurethane concrete lifting work?
We drill small ⅝” holes, inject high-density expanding foam under the slab, fill empty voids, compress loose soil, and gently lift the concrete back to level. We patch the holes after the work is done. Most slabs are ready to use shortly after leveling.
Is foam lifting better than mudjacking?
Yes. Poly foam concrete lifting is cleaner, faster, lighter, longer-lasting, and better for Texas soil. It doesn’t wash out, won’t shrink, and requires much smaller holes. It’s also ready to use almost immediately. That’s why we trust poly leveling over mudjacking.
How long does a typical job take?
Most residential jobs take 1–2 hours. Larger patios, pool decks, and commercial slabs may take longer — but it’s still much faster and cleaner than replacing concrete.
Is the foam environmentally friendly?
Yes. Our polyurethane lifting material contains 40%+ renewable and recycled content and does not contaminate soil or water. It is engineered for lifting, stabilizing, and long-term support.
Cost, Estimates & Scheduling
Is concrete leveling cheaper than replacement?
Most of the time, yes. Poly foam concrete leveling can save you 50-70% compared to tearing out and replacing concrete — and avoids the mess, downtime, and landscaping damage of replacement.
Do I need to be home for the estimate?
No — you do not need to be home. We can inspect your concrete from the outside and send a full quote by text or email. Being home is optional but helpful if you want to walk the area with us, but we make it easy for your to receive your free estimate.
Do you offer virtual/photo-based quotes?
Yes. You can upload photos through the website or text them to us for a same-day virtual quote.
How soon can you schedule my job?

Using Your Concrete After Leveling
How soon can I use my concrete after you lift it?
Most surfaces are ready to use same day! There is no long cure time like traditional concrete replacement.
Will the patched holes be noticeable?
We patch the small ⅝” holes with fresh cement. They blend in naturally over time, but they may be slightly visible on brand-new or decorative concrete.
Will concrete raising fix drainage problems?
In many cases, yes. Raising settled slabs often restores the proper slope so water flows away instead of pooling next to your home or garage.
Soil Stabilization, Void Filling & Deep Foamjection®
Can you fix large voids under concrete?
Yes. Polyurethane foam is excellent for filling voids caused by erosion, plumbing leaks, soil collapse, or washout behind retaining walls and seawalls.
What is Deep Foamjection®?
Deep Foamjection is a soil stabilization method where expanding foam is injected deeper below the slab to improve weak soil layers. It’s ideal for major settlement, clay soil movement, and heavy-load areas.
Do you repair seawalls?
Yes. We use a hydrophobic foam that cures even in water. It fills voids, seals cracks, strengthens the soil, and restores support behind seawalls and retaining walls.
Warranty, Payment & Service Area
What warranty do you offer?
We provide a 2-year limited warranty on concrete lifting. If your slab settles again within the warranty period (and site conditions are properly maintained), we will return to evaluate and address the issue.
What payment methods do you accept?
We accept:
- Checks
- Credit Cards
- Zelle
