Contractor: Lee Infrastructure Restoration
Engineer: Sandusky Water Works
Material Used: Fortec Carbon/Kevlar Grid
Water infiltration, where brick tops jopin poured concrete, due to freeze/thaw and vibration. Standard repair materials failed over time.
Fortec carbon was designed to make three monolithic to resist separation movement, thereby increasing life of the polyurethane grout and cematitious coatings.
Sewer installs performed as designed, increasing the traditional water stop life.
