    I do not have any info on foaming.  I personally would want to know how it stands up over time.   I would think the "foam" would eventually break down.  However, traditional piers don't stay where they are permanently either.  The trick is to find a foundation company that can give you the info you need honestly and openly and not give you the sales pitch.  each method has it's faults.  I would call around and see which company can give you honest opinions.  don't talk to the sales people, hopefully the owner or someone who has been in the business a long time.  it won't be hard to figure out who knows their stuff and seems upfront and honest.

    Foam to lift a slab is simply a recent modification of mud-pumping/jacking.  I believe it is useful for raising temporarily patios, drives, roads and walks, I couldn’t recommend it for structural slabs like a home foundation.  Soils in Texas expand and contract with soil moisture changes.  Each time they shrink when dried, they don’t expand back 100% when moisture returns.  However, if you have filled the void under the slab with foam or cemented materials, the slab may be lifted during wetter seasons much like when there is a water source such as plumbing leaks beneath a slab.  It is a shim, under the slab, resting on the same soils which have already failed once and does nothing to prevent future failure.
