Unchanged for half a century, the conventional maintenance hole design is now a frequent and very costly source of many problems for municipalities and taxpayers. The IFC-25 MH System is a superior system compared to the conventional maintenance hole design and is transitioning into the preferred municipal standard. Eliminate inflow and infiltration, replace the conventional cast iron frame with a 270% stronger ductile iron frame, replace fragile grade rings, minimize road deterioration, stop the constant/frequent rehabilitation cycle and save a large amount of money with the IFC-25 MH System.

There is a 25-year material guarantee for all systems that are installed following the correct procedures detailed in the Installation Guide, which can be downloaded from this website. Additionally, in the event of any third-party damage to the IFC-25 frame and/or concrete components, most repairs are simple and quick using a DECAST recommended product. DECAST's 24/7 Field Services Team can be contacted at (888) 835-7940 to assist with any repairs.
