Backfilling saturated soil
Backfilling saturated soil
(OP)
We have an open excavation (50' x 25') that needs to be backfilled. It has filled up with rain water so the soil is generally saturated. We can pump out most of the water but is there a concern for for the satuarated soil? Eventually there will be a structure in the area but we don't anticipate being ready for foundations for another year. The area would be re-excavated at the time.
The excavation is 6-9' deep.

The main thing is to get it stable and keep it dry. Having a slight slope to the subgrade / backfill, down to a pump is a good way to maintain this.
The contractor should protect his work. Obviously, this can be difficult with a big hole; therefore, there is no reason that you should not be able to ask the contractor to show the work completed / subgrade is suitable for placement of more fill.
