We televised some underground duct work for a customer to find they were in terrible shape! The metal ducts were completely rusted out and very weak with little to no structure remaining, also many holes allowing the back fill that was used around pipes(a fine crushed stone) to enter the ducts blowing dust and sand all over the house. Were were able to trenchless cast the ducts to give them structure and then apply our duct armor product to seal the system leaving a nice clean pipe and air flow!
