Spray-On Foam & Coatings offers affordable slab jacking services in Battle Ground, WA, raising sunken driveways, patios, walkways, steps and garage floors with injected polyurethane foam instead of tearing them out. If the slab is still in one solid piece, lifting usually costs much less than a new pour. If it's shattered or your house foundation is moving, we'll tell you up front.
Slab jacking means pumping material under a settled slab until it rises back into place. Older crews used a cement and soil slurry, called mudjacking. We do concrete slab jacking with expanding polyurethane, which needs smaller holes and puts far less weight back on the soil.
Lifting can't fix concrete that's broken into many loose pieces, heaved by tree roots, or crumbling at the surface. If a slab needs replacing anyway, paying to lift it first wastes money.
Water is the usual starting point here. NOAA's 1991-2020 climate normals for the Battle Ground station show about 52.4 inches of precipitation a year, with November, December and January each averaging over 7 inches while July and August get less than an inch. The same record counts roughly 70 nights a year at or below freezing. Months of runoff from roofs and driveways can carry soil out from under slab edges and joints, and winter freezes can widen cracks that let more water in. That's why we check downspouts and grading before we lift anything; otherwise the void can come back.
The ground matters too. Clark County's 2016 Comprehensive Plan earth resources review describes the Troutdale formation under the lowlands as mostly clay, silt and fine sand, and notes that Battle Ground's growth area contains places with weak soils for foundations. The county adds that these conditions are site specific and show up only through on-site investigation, so two neighbors' driveways can settle very differently. Lightweight foam fills voids without adding the heavy load a cement slurry places on soft soil, which is one reason we use it here.
Every job follows the same order, and the first step matters most. Good concrete slab jackers find out why the slab dropped before raising it.
We measure how far each panel has dropped, look for voids and check drainage around it. You get a free written quote before any work starts.
We drill holes about the size of a penny, inject foam in small stages, and watch the slab rise so it doesn't crack or overshoot. Then we patch the holes and clean up.
People searching how to jack concrete slab sections themselves usually find pry-bar and bottle-jack methods. Those can raise one edge, but they don't fill the hollow underneath, so the slab often cracks or drops again. Lifting foam and injection rigs are specialty equipment, not hardware-store cans.
We couldn't find published price data for Battle Ground itself, so the closest reliable figures come from the Portland metro area. Your final price depends on your slab, which is why we quote on site.
The Angi Portland mudjacking cost guide, updated May 2026, puts mudjacking at $4 to $9 per square foot, with most projects between $1,450 and $4,020 and small jobs often hitting a minimum around $500. It lists polyurethane foam materials at $400 to $1,200 per job versus $100 to $400 for slurry.
| Cost Factor | Why It Changes the Price |
|---|---|
| Square footage | More area takes more material and labor |
| Depth of the drop | Bigger voids need more foam |
| Number of panels | Each panel needs its own injection points |
| Access | Tight spots and landscaping add setup time |
If one small walkway panel is cracked into pieces, a new pour may cost about the same or less. We'll show you both options.
The cheapest bid isn't always the best value. A few questions sort out most concrete jacking services quickly:
We've been in business since 1973. Because we also handle soil stabilization and foundation repair, a problem that runs deeper than the slab won't send you hunting for another contractor.
If a sunken driveway, patio or step is catching toes or sending water toward your house, the next step is a quick look. Call Spray-On Foam & Coatings at (360) 667-1993 or email [email protected] for a free quote. We'll measure the settlement, explain whether lifting or replacement fits, and put the price in writing before any work starts.
It depends mostly on water. Foam doesn't wash out the way some older slurry mixes can, but if runoff keeps eroding soil beside the slab, new voids can form. Fixing downspouts and grading gives the repair its best chance.
Usually, yes. Lifting foam cures in cool, damp weather, but we schedule around heavy downpours so the surface is dry enough to patch cleanly.
The holes are about penny-sized and get patched flush. On older or weathered concrete, the patch color may not match perfectly.
Not usually. Lifting is meant for flatwork like driveways, patios, steps and garage floors. Cracked foundation walls or sticking doors point to a different problem, which we'd evaluate as foundation repair.
Foot traffic is usually fine the same day. We'll give you the exact wait for vehicles based on the foam and temperature on your job.
