Question 1

What is the difference between mudjacking and polyjacking?

Accepted Answer

Mudjacking pumps a heavy slurry made of portland cement, sand, and soil under the slab through larger drill holes. Polyjacking, a type of polyurethane injection, uses a lighter foam through smaller holes. Both raise sunken slabs, but the foam cures faster and adds less weight to weak soil.

Question 2

How long does the repair last?

Accepted Answer

How long the result lasts depends on whether the underlying soil problem was solved. If soil erosion or drainage problems continue, the section may settle again. A contractor who addresses the cause, not just the dip, is more likely to deliver long-lasting results.

Question 3

Is lifting cheaper than replacement?

Accepted Answer

Because this repair avoids demolition, removal, and pouring of new concrete, it is often considered before full concrete replacement when the existing slab is still sound. The final price depends on the size of the area, how far it has sunk, and the method used.

Question 4

Can this fix a garage floor or pool deck?

Accepted Answer

Yes. A settled garage floor, pool deck, driveway, or sidewalk can often be lifted back to level with a slurry lift or foam lift, as long as the existing concrete is still in good condition. Badly cracked or shattered sections may need to be replaced instead.
