In retrofitting expansion joint
leaks in the Wheeling Tunnel on Interstate I-70, the new expansion joints had to
be be dual-sided. An abandoned coal mine above the tunnel leaches water down
toward the tunnel. At the expansion joints the water hits the outer silicone
bellows of the DSM SYSTEM where it sheds around the outside of the tunnel to drain away. As in most tunnel applications,
by necessity, the installation
is from the negative side (inside of the tunnel).
Dual-sided, DSM-DS was installed
in the entire circumference of the tunnel. Pictures below show
in-progress and completed negative-side installation and inspection before final replacement tiles
