If you’re researching concrete leveling options, you’ll see two main methods: traditional mudjacking (cement slurry pumped under the slab) and polyurethane foam injection (a high-density structural foam injected through dime-sized holes). Both lift slabs. Only one stays put long-term in most DFW soils.
Why foam beats slurry in DFW
- Weight. Slurry is heavy — 100+ lbs/ft³ — which adds load to the same soil that already failed. Polyurethane foam runs around 4 lbs/ft³.
- Water. Slurry can wash out; the foam is hydrophobic and chemically inert. Texas soils that swell and shrink don’t bother it.
- Cure time. Foam reaches structural strength in 15 minutes. Slurry takes hours to days.
- Hole size. Foam injection uses 5/8” holes. Mudjacking uses 1.5–2” holes that are visible after patching.
When mudjacking still makes sense
If a job needs a lot of mass and budget is the deciding factor, mudjacking can be the right call. We’ll tell you that honestly when it’s true.
What we use
We work with industry-standard structural polyurethane formulations specified by the manufacturer for slab lifting and void fill. {/* TODO: name the manufacturer + product line so visitors can verify */}
