Level concrete — often in a few hours
Concrete lifting & repair in Washington & Oregon
That sunken driveway or uneven garage floor isn't just an eyesore — it's a trip hazard. Polyurethane foam injection lifts and levels sunken concrete quickly, cleanly, and for far less than a full replacement.

Polyurethane foam injection (poly-lift)
The problem
Why concrete settles — and why it matters
Concrete slabs settle when the soil beneath them shifts, erodes, or compresses. In the Pacific Northwest, wet winters, freeze-thaw cycles, and organic soils create voids under slabs that grow over time. As those voids grow, the slab above has nothing to support it and sinks.
More than an eyesore
A half-inch elevation change at a slab joint meets the ADA definition of a hazard — a real liability for commercial properties.
Water intrusion
Settled slabs create low points where water pools and infiltrates basements and crawlspaces.
Structural risk
A settled garage floor can transmit differential movement to the foundation wall.
Property value
A sunken driveway or patio is a red flag at inspection and during resale. The good news: in most cases, settled concrete doesn’t need to be replaced. It needs to be lifted.

How we fix it
Polyurethane foam injection — fast, clean, lasting
The whole process typically takes a few hours. No demolition. No concrete trucks. No days of waiting for a new pour to cure.
Drill
We drill small holes (typically 5/8 inch) through the settled slab into the void beneath.
Inject
We pump polyurethane foam through the holes. The foam expands to fill the void and lifts the slab as it cures.
Level
We monitor the lift in real time and stop when the slab reaches the target elevation.
Patch
The small drill holes are patched. The slab is ready to use almost immediately.
Done in a single visit
Most jobs complete in a single visit. You can walk or drive on the concrete immediately after the foam cures. No demolition, no concrete trucks, no days of waiting for a new pour to cure.
Exact elevation targets
We control the rate and volume of injection, so we can achieve exact elevation targets without over-lifting adjacent sections.
A new, stable base
Polyurethane foam weighs a fraction of the concrete it supports. It doesn't add load to the soil beneath — it creates a new, stable base. It bonds to almost any material: concrete, asphalt, soil.
Eco-friendly and affordable
No harmful chemicals enter the soil or groundwater. And the cost is typically a fraction of demolition and replacement — with no extended downtime.
FAQ
Concrete repair questions, answered
How do I know whether to repair or replace my concrete?
Repair is the right choice when the slab itself is structurally intact and the settlement is caused by voids or soft soil beneath. Replacement makes sense when the concrete is severely cracked, crumbling, or too deteriorated to hold the foam. A free evaluation tells you which category yours falls into.
How long will the foam lift last?
Polyurethane foam does not biodegrade, compress under normal loads, or wash away. Once cured, it forms a permanent, rock-hard support layer. The foam itself is not expected to re-settle.
Can foam lift very heavy concrete, like a thick garage floor?
Yes. The expansion pressure of polyurethane foam is significant — it can lift thick slabs, heavy equipment pads, and even pool decks. The engineer determines the injection pattern and volume needed for each slab.
Is this covered by a warranty?
Concrete lifting with polyurethane foam does not carry the same Transferable Lifetime Warranty as our pile installations. We stand behind our workmanship, and the foam material itself is designed to last — but the ongoing condition of the soil beneath the slab is outside our control. We'll tell you clearly what's covered during the evaluation.
That sunken slab can be level again by tomorrow.
