Cast Iron Frames in Concrete

[RDR89]

Hi all, I wanted to ask about cast iron frames embedded in concrete, e.g. for manholes. I am not super familiar with the process or considerations but was wondering about dissimilar metal concerns between the embedded cast iron frame and carbon steel reinforcement, and any other considerations one might need to take into account with something like this. I know people have been doing these for years, but like I said I am not familiar so wanted to ask.

TIA

Make sure they embed the right ring. If you cast it in, make sure the flange is on top. Sometimes the ring is reversible and can be placed on top of concrete or embedded into the concrete. You want to make sure the flange is on top so you have a lot of concrete below the flange. This gets flipped a lot unfortunately. Some ring only goes one direction and it is only made for bolt on application.
