Design Approach, Inspection For Manhole Rehabilitation Technologies

3nd In A 3-Part Series
By Gerhard “Gerry” P. Muenchmeyer, P.E., NASSCO Technical Director | November 2011, Vol. 66 No. 11

Even though a deteriorated manhole is typically still capable of sustaining external soil loads (unless, of course, it is actually collapsed) the design of a full structural manhole within a manhole is not typically required. What is required are qualified technology installers and inspectors that are not only trained, but understand products and failure mechanisms that can be prevented during coating or lining applications As the manhole rehabilitation industry continues to grow we may see additional advances and a consensus on the best approach for structural design when required.
