Cone Replacement Forms

Manhole Cone Replacement Forms

For rehabilitation projects that require extended manhole adjustment, our standard 4′ diameter forms with cone section are compatible with all types of existing manholes – brick, precast, fiberglass, or cast-in-place. With our Cone Replacement Forms avoid complications trying to secure precast to existing brick or attempting to match varying precast joints. Simply secure the 1st riser section at the manhole break point, stack to desired height, and pour a one-piece-joint-free¬†manhole adjustment.

Another benefit of our Cone Replacement Forms is the ability to dowel in steel reinforcement throughout the manhole adjustment for highway/heavy-traffic manhole cone replacements.
