Pier Repairs

Owner: Mayes County Commissioners

System: Underwater Grouting

Completed: 2000

Description:

Since constructed in 1922, water flowing around the footing on pier # 2 caused scouring damage under the footing.   Underwater inspection brought concerns that repairs should be made to restore the structural integrity.   A repair design consisting of underwater placement of +/- 6” aggregate placed prior to the pumping of cementitious grout with “anti-washout” admixture into pipes placed around the footing at the scour locations.  Work was performed using divers and a crew placed on a barge in the water.
