Situation
A sanitary manhole at the intersection of North Lake Way and Mockingbird Trail in the Town of Palm Beach, Fla., was a heavily deteriorated brick structure exhibiting the presence of groundwater infiltration. Additionally, the bench and the inverts were compromised due to wastewater traffic. With one additional service feeding the manhole, the structure was consistently surcharged. The city was looking for structural rehabilitation and a fast return to service. SAK Construction, LLC of Puyallup, Wa., a Sprayroq Certified Partner, turned to SprayWall to solve the problem.

Solution
As a standard procedure, the manhole was pressure washed at 3,000 PSI to remove debris. SAK prepared the structure, utilizing a hydraulic cementitious mortar to provide a smooth substrate vital to the successful adhesion of Spraywall Urethane Coating. Please note that new bench and trough structures were created to ensure a smooth transitional channel for the existing inflow and effluent flow.
