When to backfill a foundation?? 1

[tocida]

After a foundation wall is poured what is the recommended time frame before backfilling?

You should get 70% of your 28 day strength in about 14 days. It depends how high you're backfilling also but I would say a minimum of 14 days.

It also depends on how the wall was designed. If it is a cantilever wall you may be correct. However, if it is a restrained wall and utilizes the slab above for support, I wouldn't recommend backfilling until the upper slab is in place and has reqached specified strength.
