Abstract
In concrete pier, pier with collar, and caps with helical, rock and soil anchor foundations, a corrugation filler mold is assembled onto the outer end of horizontally extending radial bolts to be post-tensioned. The filler mold receives the bolt outer end through a hole and fits into the adjacent corrugation trough on the outside surface of a corrugated metal pipe (CMP) defining an inside and/or outside surface of the pier foundation. The filler mold forms an enclosed cavity surrounding the radial bolt which can then be filled with cementitious material. When filled and cured, the filler mold and cementitious material stabilize the radial bolt in its horizontal position and the pier foundation during and after post-tensioning.
