Televised ducts under slab floor. Ducts are concrete with metal fittings. There were signs of water in the ducts at one time but they were dry at the time of the inspection. Suggest possible coring into the foundation wall on the left back side of the house where there are two sump pumps already. On the right side possible regrading and installation of a water barrier to prevent excess water from entering the pipe. will provide proposal for possibly spraying ducts with Duct Armor duct lining material to encapsulate the concrete ducts.
