Re: 20' foundation walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You might be able to pour the 20' using self-consolidating concrete (SCC). You would have to contact your local concrete supplier to see if it is available. Here is a link with information:

Dear List,

Designing 20' deep, restrained foundation walls for a residential
structure. The water table will not be known until the dig is begun.
Aggressive timetable of course.

I am expecting some water regardless, and am concerned that 20' is too deep for a single pour. There is rebar, of course, but is there more about the concrete mix or the lift heights that I should be concerned about and specifying to the
contractor?

Thank you for any direction that you might be able to give.
