Sometimes we do get off the roof at Whiting Construction. This time, it was to spray the steel forms used by PCL construction for pouring the concrete columns which will support the new Ernest F. Lyons bridge. SPF is applied to the forms for the purpose of retarding cooling of the concrete as it cures within the molds.
Pictured here are Lloyd Hughes and Jake Neves applying SPF to a section. The molds were sprayed on the ground and then lifted into place via crane.
