Lake Heron Overflow Discharge Pipe
Two factors not looked on positively in the coatings world are water and weather, and this project involved plenty of both. Water was the primary problem, since the pipe was located in the lake. The water had to be blocked out and dried up before the project could continue. This was achieved by stopping the infiltration with a chemical grout pumped into the openings, then using a blower to dry the structure.
Weather entered the picture in the fact that the lake was completely covered with thick ice, except around the edges. Since it was January, most of the region’s lakes had frozen over. However, the ice would now have to be counted on to support the significant weight of the bridge technicians would need to build to reach the pipe. Upon testing, the crew was assured that the bridge would hold, so they proceeded to set up their safety equipment.
With water and weather issues out of the way, the crew began to prep the structure and get ready to spray. The pipe would require 300 ml. of Sprayroq Spraywall to give the structure the corrosion barrier and structural protection it needed.
