Conduit seals at manholes
Conduit seals at manholes
(OP)
Anyone know of a paper or article that summarizes various conduit seals for waterproofing and water pressure? Looking at hydrophilic foams but don't have any experience with them.
Thanks.

91082...,What is that South Beverly Hills? Just kidding. I have had very good results with CSD Sealing Systems North America. They have several systems, some fire rated, some gas and moisture tight. Look through their catalog and contact their technical services guys. They are very responsive and helpful. Their original mandate was shipboard systems, now their landside systems are getting popular as well.

Our problems were usually leaking manholes and leaking ducts with the field personnel looking for easy cheap solutions. Duct seal and other putty type compounds could not withstand the hydraulic pressure. We could hear them popping out as the rains came.
