Continuous Footing Under Pile-Supported Wall?
Continuous Footing Under Pile-Supported Wall?
(OP)
This is a survey: Do you show a continuous footing or mud slab or nothing below c.i.p. basement walls that span between deep foundations? Do you put a note on the drawings that slab-on-grade adjacent to bottom of wall must be in place prior to back-filling behind the wall?






RE: Continuous Footing Under Pile-Supported Wall?
If the stability of the wall is dependant on the slab, then it must be installed before backfilling. If support at the top of the wall is requried, then the floor has to be installed also before backfilling.
In this situation, I prefer to pour the piles, then a grade beam (which is designed to span the piles) monolithically with the slab, then the wall. So this way the wall doesn't have to span the piles.

I use a note that the contractor is to provide for lateral support at the top and bot of the wall prior to backfilling against the wall.
