MANHOLE BARREL RINGS COMING OUT H2s
MANHOLE BARREL RINGS COMING OUT H2s
(OP)
Has anyone had experiences with concrete manholes that have their section (barrel) sealing rings coming out. This is do to the H2s problem within the linage. I know how to seal the manhole from the H2s. But, what do I do with the seal rings/gaskets that you can see within the manhole?. I have one that you can see 3' of the ring gasket. Do you cut them then seal off the area?
Suggestions!

Most of the manholes we rehabilitate are in such bad shape that the gasket material squeezing out is way down the list in priority.
