Manhole and sewer cover failure is rarely caused by metal failure but rather results from a support or installation failure from the way in which manhole covers, drains, weather, and modern road traffic conditions interplay. Such failures can create serious risk to motorists and the public and need to be addressed. Conventional methods can be expensive, require stopping or detouring traffic during lengthy repairs, and may not always be effective.

In this case, Fortress carbon was designed to make three monolithic to resist separation movement and resolve the problem.



Date: May 12, 2002
Structure: Sewer Man-hole, Sandusky, Ohio
Contractor: Lee Infrastructure Restoration
Engineer: Sandusky Water Works
Material Used: Fortress Carbon/Kevlar Grid

Project Scope:
Water infiltration, where brick tops join poured concrete, due to freeze/thaw and vibration. Standard repair materials failed over time.



Solution:
Fortress carbon was designed to make three monolithic to resist separation movement, thereby increasing life of the polyurethane grout and cematitious coatings.



Observations:
Sewer installs performed as designed, increasing the traditional water stop life.
