THREE-SIDED HYDRATITE SEAL
Infiltration In Semi-Elliptical Tunnel
This large drainage system, underlying a major highway, was experiencing infiltration at the joints, which caused concern for sinkholes and soil stability. The above roadway configuration would make excavation incredibly expensive and disrupt traffic patterns, so a trenchless solution was decided upon.




Initially, HydraTite was going to be installed, as it has been in so many other projects before, wrapping around to cover the entire joint. However, the invert was not uniform from previous repair attempts. The project owners requested a three-sided seal that would not run along the bottom.


22 standard-width seals were installed in roughly a week. HydraTite will protect the above highway and is faster and more cost-effective than repairs requiring excavation.
