The 6-Step Process
Whether we use mudjacking or polyjacking, the underlying process is the same. Here is what happens from the moment our crew arrives to the moment you drive on your repaired slab.
- 1
We arrive and inspect the slab.
We walk the slab with you, identify low spots, check the soil around the edges, and confirm the written quote we sent. No surprises before we start.
- 2
We drill 4–6 small entry holes.
Each hole is about the size of a quarter. They are drilled in a pattern designed to lift the slab evenly, usually along the edges that have settled the most.
- 3
We pump material under the slab.
For mudjacking, it's a cement-and-soil slurry custom-mixed on site. For polyjacking, it's a two-part polyurethane foam injected through the holes. Either way, the material flows under the slab and fills every void.
- 4
The slab rises back to level.
As the void fills, the material exerts upward pressure and the slab physically lifts back to its original grade. We watch carefully and stop pumping at exactly the right moment.
- 5
We patch the entry holes.
Each quarter-sized hole gets a concrete patch flush with the surrounding surface. Within a few weeks of weathering, the patches blend in and become nearly invisible.
- 6
You're back in business the same day.
You can walk on the slab in 15 minutes (polyjacking) or about 30 minutes (mudjacking), and drive on it the same day in most cases. No week-long curing period like a new concrete pour.
