ICM Manhole forms have been in use around the United States since 1970. The ICM forms allow two workers to build a complete pour-in-place manhole in less than four hours. Monolithic manholes offer the best protection against infiltration by eliminating joints and gaskets. Monolithic manholes also offer superior structural strength to combat ground shifting and freeze / thaw situations.
