Mudjacking can last for long periods, but it is inherently less reliable and usually does need to be replaced. The injected materials are extremely heavy (30-50 times heavier than their polyurethane equivalent) and can cause a new round of soil compression (and foundation sinking) beneath the slab.

Can you use spray foam under concrete slab?
Insulating under foundation and basement slabs using SPF ( spray polyurethane foam ) offers certain advantages over the more common method of using rigid foam board. Only closed-cell SPF can be used in a subslab installation; the open-cell foam does not have adequate compressive strength.
How do you fix a sunken concrete slab?
The least expensive way to raise a sunken slab is to inject a combination of dirt, aggregate and Portland cement through holes in the surface. This process is called mud jacking, and it’s a job best left to pros with the equipment to do it, because the material has to be injected under pressure to do the job.
How do you lift a sunken concrete slab?

The process is sometimes called “ slab jacking” or “pressure grouting”. 1 to 1 5/8th inch diameter holes are drilled through the sunken concrete block/ slab at strategic locations to maximize lift.
Do it yourself foam jacking?
