The Ajax market for oil-grit separators for Oil-Grit Separators in Ajax

The Ajax market for oil-grit separators

Ajax's need for oil-grit separators (Durham Region) is driven largely by automotive and parts manufacturing, logistics and distribution, food processing, and institutional. Ajax's Bayly and Salem industrial corridors feeding the 401 anchor a strong automotive, logistics, and food-processing construction market. Demand centres on industrial slabs, truck courts, servicing, and loading-dock work.

Most of it sits around the Clements and Bayly industrial corridor, Salem Road business park, and the 401 employment lands. Clients such as manufacturers, distributors, healthcare, and the Town of Ajax drive much of the Ajax work, and no two projects carry the same scope or ground.
