We appreciate the kind words!
Under slab leak detection service call. Televised ducts under slab floor. Ducto are galvanized with heavy rust allowing sand to enter. Suggest spin cast mortaring then spray lining with Duct Armor.
We lined the sewer for a customer, from an outside clean out which was recently installed in front of the house, about 85’ out to the lateral to city main connection
