Mudjacking vs Polyurethane Foam Lifting in Sioux Falls
Every concrete lifting company has a favourite method — usually the one it sells. Concrete Raising Sioux Falls sells both, so here is the comparison without the sales pitch: mudjacking and polyurethane foam both lift a slab, and the right one depends on the slab, the soil and the budget, not on which brochure you read.
The short version: mudjacking is cheaper, heavier and proven over decades; foam is lighter, faster and gentler on decorative concrete. The table below is the whole argument, and the page below it explains when each one wins.
The side-by-side table
| Mudjacking | Polyurethane foam | |
|---|---|---|
| Cost per sq ft | About $3–$8 | Higher (nationally up to ~$25) |
| Material weight | ~100 lbs per cu ft | ~2–4 lbs per cu ft |
| Hole size | About 1–2 inches | As small as ⅜ inch |
| Cure / ready to use | Hours to a day | About 15 minutes |
| Best for | Large slabs, deep voids, budget | Decorative concrete, speed, soft soils |
| Weakness | Visible holes on stamped concrete | Cost; overkill for big plain slabs |
Port size matters more than most people expect: mudjacking's 1–2-inch holes are patched with concrete and fade on plain slabs, but they show on stamped work. Material weight matters too: at roughly 100 pounds per cubic foot, slurry is a stable, dense fill — but on soft, saturated soil after a wet Sioux Falls spring, foam's 2–4 pounds per cubic foot is an advantage.
When mudjacking wins
Large slabs and long runs — driveways, warehouse floors, long sidewalk stretches — where foam would need many more injection points. Deep voids, where a heavy, dense fill is exactly what the slab needs. And budget-first jobs: at $3–$8 per square foot against foam's higher rate, mudjacking is the cheapest way to get a sound slab level, and for a plain concrete driveway it is usually the right call.
- Large slabs and deep voids
- Budget-first jobs
- Plain concrete where holes will not show
- Garage and warehouse floors
When foam wins
Stamped, stained or decorative concrete, where a ⅜-inch hole disappears and a 1–2-inch hole does not. Slabs that must be used again the same day — a driveway that must carry cars that afternoon, a storefront walk that cannot close. Soft or saturated soils, where heavy slurry would add to the problem. And interior floors, where the small holes and fast cure keep the disruption minimal.
- Stamped and decorative concrete
- Same-day use required
- Soft or wet soils
- Interior garage and basement floors
The question customers actually ask
Industry research on hundreds of lifting-company reviews found that fewer than 5% of customers even mention which method was used — they mention price, communication and whether the slab is level. That is the honest frame: choose by the slab, not by the material. Our estimate recommends a method after the inspection, and when both fit, we will quote both and let you choose.
Questions
Which is better — mudjacking or polyurethane foam?
Neither, in general — the right one depends on the slab. Mudjacking wins on large slabs, deep voids and budget. Foam wins on decorative concrete, same-day use and soft soils. A company that sells only one method will always tell you it is the better one; we offer both and recommend after the inspection.
Which lasts longer?
Both last when the voids are filled and the joints are sealed — what lasts is the fix underneath, not the material. A lift that fails usually fails because water got back under the slab, which is why sealing is part of every job we do.
Can I get a quote for both methods?
Yes — when both fit your slab, we will quote both, with the trade-offs explained, and let you choose. The estimate is free either way.
