I would get the soil in the basement excavated and put up a foundation wall.

.- Any soil contact with posts on wood-frame elements like a deck or patio?

Hi, I found an apartment that I love but in the bulding there is a oil tank with soil contamination.

The property is probably going to stay a single family house sense foundation from swelling soil over 100 years has caused massive cracks throughout the entire basement foundation.

Some of Houston soil is terrible.

Realistically my wife and I are probably 2 years out from being able to invest in one but have seen some west of I-35 in round rock (don’t go east as the black prairie soil is horrendous for all the settlement issues).

@Sandy S.That’s exceptionally long, 14 days should be more than enough.

What TSP also does is work on heavily soiled areas, including residues of old oil-based paint.

If the house is on a concrete foundation, walk around the house and look for any spots where the soil is missing or a hole is obvious.

If u plan to take the building down as opposed to repurposing it, you may encounter contaminated soil that was previously capped by the slab.the estimate sound low on the low end to me.
