RE: Acidic Soil

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You can formulate a concrete mix that would resist some measure of acid, but a barrier is more of a sure thing. A barrier is what is used commonly in areas like Saudia Arabia for sulfate resistance.

I would suggest:
1.  Place a heavy membrane (similar to a T-Lock) on grade
2.  Place the rebar
3.  Form the sides of the foundations
4.  Place the concrete
5.  Strip the forms
6. Apply a liquid membrane (a polyeurethane) on all vertical and exposed horizontal surfaces to be in contact with the soil

Regards,
Harold Sprague

I have a situation in which the sandy soil has a PH of 4.  Never run
across this before. Any recommendations on the type of cement to use in
the foundations.
