Illustrative Example: A 1½-Inch Driveway Lift, Explained Step by Step

This article is an illustrative example, not a documented Spokane customer project. The scenario below is written to help homeowners understand how a typical residential driveway lift is planned and performed — the sequence, the tools, and the reasonable expectations. Any specifics (measurements, port counts, timing, price ranges) are provided as generalized industry norms.

The Scenario

Picture a residential driveway on a typical Spokane property. The slab near the garage apron has settled roughly 1½ inches, and water is pooling toward the foundation after rain and snowmelt — a warning sign covered in why water is pooling on your driveway. The concrete itself is structurally sound: hairline cracking along a control joint, no spalling, no crumbling. Two replacement quotes came in over $12,000 each.

Because the concrete is still in good shape, this is exactly the kind of slab that concrete leveling is designed for — the trade-offs between lifting and replacement are covered in concrete leveling vs. concrete replacement.

How a Lift Like This Would Typically Be Performed

1. On-site assessment

A technician measures the offset, checks slab thickness, looks for voids underneath, and identifies the drainage cause — often a downspout dumping directly onto the driveway edge. See downspouts and slab settlement for the most common culprit.

2. Drilling injection ports

Small dime-sized ports (typically 5/8 inch) are drilled through the slab in a pattern matched to the void — often four to eight ports for a two-car apron section.

3. Injecting polyurethane foam

Structural polyurethane foam is injected in controlled bursts. As the foam expands, it fills the void beneath the slab and gently raises the concrete back toward its original grade. Contrast with older methods in polyurethane foam vs. mudjacking.

4. Sealing and cleanup

Ports are sealed with color-matched patching. Control joints along the lift area are resealed. A driveway can typically be driven on the same day, because foam cures in minutes rather than hours.

What a Homeowner Can Reasonably Expect

• On-site time for a project this size: often two to four hours
• Total invested: typically a fraction of a full replacement
• Written warranty on the lifted area
• Same-day return to service in most cases
