This is new construction with 8" concrete walls 8 feet high. On the back wall of the house there is a 52 foot span of wall with bulkhead steps at about 10 feet from one end. There is a large crack and the wall has bowed in half and inch. Foundation was poured in September. I am thinking that this was caused by improper backfill around the foundation. Contractor was supposed to use coarse sand but instead it was backfilled with the surrounding soil which contains lots of clay.
The house is in Maine with obvious frost considerations. I have already had substantial water infiltration during rainstorms. The water flows right into the crack and doesn’t seem to be reaching the perimeter drain system that was installed around the footings.
Was this proper construction procedure, and how do i remedy this situation?
thanks in advance…
