Slab Foundation Repair in Shreveport, LA

Slab foundation repair fixes a concrete slab that’s settling, cracking, or shifting. Most repairs use one of two approaches: steel or helical piers driven to stable soil to lift and support the slab, or polyurethane foam injection to fill voids and raise sunken sections. A Pelican Foundation Repair specialist inspects your slab first — free — and recommends whichever method fits what your slab is actually doing.

Here’s what a lot of homeowners get wrong about slab cracks: the crack is the symptom, not the disease. Sealing a crack without fixing the settlement underneath is a temporary cosmetic job — the slab keeps moving and the crack comes back. That’s why every repair we do starts with finding out why the slab moved in the first place. Soil? Water? A plumbing leak underneath? The answer changes the fix.

Signs Your Slab Foundation Needs Repair

Slab problems show up in the house long before most people connect the dots. If you recognize these, your slab deserves a look:

• Diagonal cracks running from window or door corners toward the floor
• Cracks in the slab itself — visible in the garage, patio, or where flooring has been pulled up
• Uneven or sloping floors, especially a tilt you can feel walking across a room
• Doors and windows that stick or no longer latch
• Gaps between the baseboard and the floor, or between the wall and ceiling
• Water pooling against the slab edge after rain
• A chimney or porch pulling away from the main house

One hairline crack in a garage floor might be nothing. But cracks plus sticking doors plus a sloping floor? That’s a slab telling you it’s moving. A free foundation inspection with elevation readings will tell you exactly how much.

Pay special attention to cracks that change with the seasons. A crack that’s tight in March and gaping in August is responding to the clay swelling and shrinking — that’s active movement, not a one-time event. Take a photo of any crack you spot and date it; when we come out, that timeline helps us tell whether the slab is still moving or whether it shifted years ago and stabilized.

Why Slabs Settle in Shreveport

Most slab settlement in Shreveport traces back to the same culprit: expansive clay soil. In Broadmoor, Cedar Grove, and South Highlands, we’ve seen the same pattern hundreds of times — clay pulls away from the slab edge during dry months, leaving a gap, then swells back during heavy rain. That repeated cycling loosens the soil’s grip on the slab, and over the years, sections of the slab start to drop.

The Other Common Causes

Clay isn’t the only troublemaker. Poor drainage is a close second — gutters that dump water right at the slab edge, or a yard that slopes toward the house instead of away from it, saturate the soil on one side and cause uneven movement. Plumbing leaks under the slab wash soil away and create voids; tree roots from a big oak near the house can drink the moisture out of the clay and shrink it. During your inspection, we check for all of these, because the repair has to address the cause — not just lift the slab back up.

Newer Subdivisions Aren’t Immune

People assume slab problems only hit old houses. Not true. Newer homes in Benton, Haughton, and the developments off the Bert Kouns corridor sometimes settle because the fill soil under the slab wasn’t compacted well, or because the builder didn’t account for how aggressive local clay is. Age doesn’t protect a slab — soil conditions do.

How We Repair Slab Foundations

No two slabs get the same treatment. Here’s what the options look like and when each one makes sense.

Steel Push Piers and Helical Piers

For real settlement — where a section of slab has dropped — piers are the heavy-duty answer. Steel push piers are hydraulically driven through the slab down to stable, load-bearing soil, then the slab is lifted back toward level. Helical piers screw into the ground like giant screws and work well in softer or wetter soils. Either way, the weight of that part of your home ends up resting on soil that doesn’t swell and shrink with the seasons.

Polyurethane Foam Injection

For slabs with voids underneath or moderate sinking, polyurethane foam gets injected through small holes in the slab. It expands, fills the voids, and lifts the concrete back up. It’s fast — most jobs finish in a day — and it doesn’t tear up your landscaping the way excavation would. It won’t fix deep settlement the way piers do, but for the right situation it’s the cleanest option.

Crack Repair

Structural cracks get sealed with epoxy or polyurethane injection through our foundation crack repair service, which bonds the concrete and restores strength. But here’s our rule: we don’t inject a crack until we know why it formed. If the slab is still moving, the crack repair comes after the stabilization — otherwise you’re sealing something that’s about to crack again.

Drainage Correction

If water caused the problem, the repair plan includes drainage correction — regrading, gutter extensions, or a French drain — so the same water doesn’t undo the repair in three years. This is the step cheap quotes skip, and it’s the reason their work doesn’t last.

Our Slab Repair Process

You’ll know exactly what’s happening at every step. No surprises.

• Free on-site evaluation — We measure elevations across the slab, check crack width and direction, and inspect grading and drainage for contributing causes.
• Written diagnosis — You get a plain-language explanation of whether the slab is still settling, what’s causing it, and which repair method fits.
• Written estimate — Pricing tied to the specific repair method, in writing, before any work begins. No verbal quotes.
• The repair — Our crew performs the pier installation or foam injection, working around your patio, driveway, and landscaping as much as possible.
• Final walkthrough — We confirm the new elevation readings with you and provide written warranty documentation. Qualifying repairs carry our 20-year structural warranty.

Most slab jobs finish in one to three days, depending on how many piers are involved. You’ll get a firm timeline in your estimate — not a vague “a few days.”

Wondering what repair day looks like? For pier work, the crew excavates small sections along the slab edge, drives the piers, and lifts gradually — you’ll hear the equipment, but most homeowners stay in the house the whole time. For foam injection, it’s even quieter: small holes drilled in the slab, foam injected, holes patched. Your yard and driveway take minimal disruption either way, and we walk the property with you before we leave.

Slab Repair Costs: An Honest Breakdown

Let’s talk numbers honestly, because vague pricing helps nobody. Costs depend on the repair method, how many piers are needed, and how far the slab has settled:

The exact price always comes from the inspection — pier count, slab condition, and soil behavior all factor in. Anyone who quotes you a price over the phone without seeing the slab is guessing. We don’t guess.

One more thing that affects cost more than people expect: access. A slab with a clear perimeter is faster and cheaper to pier than one boxed in by a new patio, a pool deck, or mature landscaping we have to work around. That’s another reason the in-person inspection matters — we price the actual job, not an idealized version of it.

Frequently Asked Questions

Can a slab foundation be fixed without replacing it?

Yes, in most cases. Piers, foam injection, and crack repair stabilize and lift settled slabs without tearing them out. Full replacement is rare and usually only needed when the slab is severely deteriorated.

How do you fix a cracked slab foundation?

First we determine why it cracked — settlement, soil movement, water, or a plumbing leak. Then the fix matches the cause: injection for the crack itself, piers or foam for settlement underneath, drainage work if water is the culprit.

How long does slab foundation repair take?

Crack and foam injection jobs usually finish in a day. Pier installations take two to five days depending on pier count. Your written estimate includes the timeline.

What time of year is best for slab repair?

Any time. Slab repair works year-round in Shreveport. If anything, the dry summer months make settlement easier to measure accurately, since the soil has shrunk to its worst-case position.

Does homeowners insurance cover slab foundation repair?

Usually not for normal settling or soil movement. If a sudden covered event — like a major plumbing leak under the slab — caused the damage, you may have a claim. Your agent can confirm.

How do I keep my slab from settling again after repair?

Two things: manage water and watch the soil. Keep gutters discharging at least several feet from the slab, make sure the yard slopes away from the house, and don’t let big trees drink the clay dry right against the foundation. After a repair, we’ll tell you exactly what to watch for around your particular home.

Will the cracks come back after repair?

Not if the cause is fixed. That’s the whole point of diagnosing first: once the slab is stabilized on piers or the voids are filled and drainage is corrected, there’s nothing left to reopen the crack.
