St. Clairsville, OH, USA

Description:
The popular 532-foot (161m) long, 40-foot (12m) high St. Clairsville bike tunnel was plagued with water leakage and, in colder months, ice build-up, making the tunnel unsafe.  An innovative construction solution used PENETRON crystalline waterproofing technology to waterproof both the previous concrete structure as well as the new liner.  The results exceeded the engineers’ expectations.

Products Used:
A combination of PENETRON slurry applied over a concrete liner with an integrated drainage system for active leaks and a PENETRON ADMIX Enhanced Shotcrete (PAES) to treat the newly reinforced shotcrete interior surface of the tunnel.
