If it has been more than two years and I believe it has you might have to start from scratch with all of the required engineering, soils analysis, foundations designs etc, . etc.

As others have mentioned, Texas is notorious for foundation issues due to soil conditions and high property taxes which can be mitigated by knowing what you're doing and being close by.

Maybe put soil on everything so the broken cement surface and the dirt area is covered with the new soil.

I'm eliminating a carpeted area that was soiled by a pet.

what we have done in the past is to spray the soil with weed killer to destroy anything already there.

Sand is one option but I have heard about a expanding foam that some epa approved company has.

All contaminated soil would have to be removed and bagged.

Agreed with Marcus...hire a structural engineer to determine the cause and extent of the problem, talk to a company that does foundation (or perhaps water-proofing) repairs, and factor the estimate into your rehab costs.Additionally, you'll have to disclose the work to potential buyers, and if you don't plan to finish the space (framing/sheetrock), expect that your resale value may be impacted when buyers see the fix.Often, a horizontal crack is the result of static pressure from the soil on the other side of the wall.

Sandy S Harris - I don't remember which book of Stanley's it was in, I think one of the early books, but he tells of how he was interviewing deca-millionaires.
