FOUNDATION FIXERS
★ Hero Service · § 01.A

Foam Injection Foundation Leveling — our signature service.

This is what Foundation Fixers is built on. Polyurethane foam injection is the most advanced, efficient, and long-lasting method for lifting sunken foundations and concrete slabs. We bring the same technology used on highways and runways to your driveway, your foundation, and your pool deck.

§ 01 How it works

Six steps. Roughly four hours.

The process is straightforward — and that's the beauty of it. Compare with the 3–5 days (plus weeks of curing) for tear-out and replacement.

01

Drill

Penny-sized holes (≈5/8") through the slab — a fraction of mudjacking's 2-inch holes.

02

Inject

A specialized injection gun pumps high-density polyurethane foam through each hole.

03

Expand

Foam expands roughly 20× its liquid volume beneath the slab.

04

Fill & lift

It fills voids, compacts loose soil, and lifts the concrete back to level.

05

Laser-level

We monitor the lift with laser levels and stop precisely when level is achieved.

06

Patch & go

Holes patched. Surface ready for foot traffic in 15–30 minutes.

Same-day foam injection results.

What it actually feels like to be done in a few hours instead of a few weeks.

§ 01 ★★★★★
Our driveway had dropped almost two inches at the garage and I was bracing for a full tear-out. Foundation Fixers showed up, drilled a few small holes, and had it level the same morning. We were parking on it that afternoon.

§ 02 ★★★★★
The pool deck was sloping toward the pool and the coping was pulling away. They walked me through every option, told me what I didn't need, and quoted half what another company did. Job took about three hours.

Pool deck leveling
§ 03 ★★★★★
We had stair-step cracking on the back of the house and I'd been stalling for a year because I didn't want a sales pitch. Daniel came out, did a real assessment, and told me it was actually a soil-void issue we could fix the same week with foam injection. Honest people.

§ 04 FAQ

Foam injection — common Phoenix questions

How does polyurethane foam injection actually lift concrete?
We drill penny-sized 5/8" holes through the slab and pump in two-component polyurethane. As the components mix they expand to about 20× their liquid volume, compressing loose soil and filling voids underneath. The expansion pressure lifts the slab back to level, then the foam cures hard in about 15 minutes.
How does foam compare to mudjacking (slurry / mud lifting)?
Foam weighs 2–4 lb/cubic foot versus 100–150 for cement slurry, so it does not re-load the failing soil. Foam holes are 5/8" vs 2", patches are nearly invisible, and the foam is closed-cell and waterproof — it will not erode, shrink, or decompose like a slurry can.
Is the foam safe — does it leach into soil or groundwater?
Yes, the foam is environmentally inert once cured. It is closed-cell and chemically stable — no leaching, no off-gassing, no breakdown. The same material is used under highways, airport runways, and around utility lines.
How long does a foam injection job last?
Permanently. The foam does not shrink, settle, or decompose. The only way the surface can move again is if new movement happens in soil that has not been treated — for example, a plumbing leak or new void forms elsewhere. Our warranty is transferable to the next owner.
What is the smallest foam injection job you will take?
We routinely do single-section sidewalk lifts, single AC pad lifts, and small driveway corners in the $400–$800 range. There is no minimum job size — if it is worth fixing, we will quote it.
Can you inject foam in Phoenix summer heat?
Yes. The foam is engineered for hot conditions; cure time is even faster in 100°+ ambient temperatures. We schedule work for early morning during peak summer so the crew stays safe, but the material handles the heat without issue.
