Shield Basement Systems

At first was thrilled with waterproofing then the small job promises s/b just as important. Repeated requests, to remove remaining construction material was hidden behind my shed; have to hire someone to replace large window screen damaged by workers. Repeated requests to fix sidewalk which has all shifted down towards the house with sink holes under. Air conditioner has now sunk 8" on an angle. Poor calculation of materials required for tamping? Finally looked at it in June. Was a no-show in September when promised and no call. Still not dealt with haven't heard back.
