This 55,000 sf warehouse in Rexdale was a food storage facility for many years. The floors had a great slope to drains. Because the location has railway access it was chosen to be a paper storage facility. 10,000 lb paper rolls need to be stacked 20 ft into the air. A flat floor is required to keep the stacked paper rolls straight. Self levelling could not be used as it does not have the hardness or compressive strength to take these loads- concrete was chosen as an overlayment.
We shotblasted the floor installed an epoxy bonding agent and had 300 cubic meters of concrete delivered, placed and finished.
