I recently completed a job where I inspected and cleaned ducts under a slab floor. The ducts were made of PVC and had metal elbows. I found some sand in the joints, but no signs of water issues. I will provide a proposal for spray lining the ducts.
Under slab leak detection service call. Televised ducts under slab floor. Duct are PVC ducts with metal fittings and connections that are allowing sand to enter the system. The plenum is also very rusted and deteriorated. Will provide a proposal for spin cast mortaring then spray lining ducts.
Televised sewer from inside clean out on stack out to pit outside. There is a broken tile but sewer can still be lined. Propose for installing liner in either one or three lines.
Televised ducts under slab floor. Ducts are galvanized metal and very rusted. There was standing water in ducts at time of inspection. Downspouts need to be extended above ground. If after taking care of downspouts the water still gets in system a sump pit and pump would be needed to control water. After water is controlled the ducts should be spin cast mortared then spray lined with Duct Armor duct lining material.
