Contractor just broke ground last Friday, found the old septic tank original from 1952 when the home was built. City sewers came eight years later in 1960 so the septic tank has not seen anything new since that time. Uncovered it and it was full of water, excavator had it pumped out and broke up the upper part of the chamber, left the rest alone below where the new footing will go. Contractor was going to fill it with rock and concrete, maybe some rebar.
Town engineer came by on Monday and failed the excavation, wants contractor to make sure the load bearing capacity of the soil underneeth the old septic pit meets the minimum in our area, NJ all clay two feet below grade, I think it needs to be 2500 lbs per sq ft. So we have a soil engineer coming to test it.
Does anyone have any thoughts on this they can share with me? Not familiar with the engineering involved in a foundation for a new home, not like we're building a wal-mart or something. Obviously I don't want it to shift ever, either.
Thanks!
