Showing the video of the damage and after the repair was everything to me. Nothing boosts confidence of a decision more than knowledge.
Televised ducts under slab floor. Ducts are clay tile ducts with metal elbows. Customer is having issues with water getting into the ducts. They have recently had a sump pit installed. Looks like they need more perforated hole in the pit to allow more water into the pit. They are going to have contractor come back to open holes larger and drill more holes. After water issues are resolved the ducts should be spin cast mortared on the joints then spray lined with Duct Armor duct lining material. Customer also needs to run downspouts out and pitch them better.
Video inspection of underground air ducts due to smell in one of the rooms. Customer is suspecting something dead in the duct. Camera showed that all duct runs were clear with no problems.
We lined the sewer from an outside clean out about 20’ to a manhole, the clay tile pipe was severely cracked and broken. With the liner the pipe is like new pvc within the old broken clay tile.
Video inspection of underground air ducts. Ducts are metal and extremely rusted. Sand is filling the ducts making it impossible to get the camera from one end to another. Suggest trying to clean ducts to remove sand.
Video inspection of under slab air ducts. Ducts are extremely deteriorated but can be repaired by spin casting a new concrete duct and the spray lining with Duct Armor. All this with no digging!
