Toronto Pearson International Airport - Glycol Waste Storage Tanks

Milman & Associates was retained by the GTAA to inspect and rehabilitate the glycol waste storage tanks at Pearson airport with a combined volume of 12,000 m3. The purpose of the tanks is to collect the waste glycol from de-icing of aircrafts. Leading all aspects of the project, we designed the waterproofing and repair of the tanks, and issued all drawings and specifications. These included selecting appropriate waterproofing materials and method of application and crack repairs.

Due to the compromised condition of one of the tank’s existing membrane, it was removed and replaced with a cementitious crystalline waterproofing material. Our team also conducted full-time construction supervision and contract administration for the project.
