The Ajax market for underground utilities for Underground Utilities in Ajax

The Ajax market for underground utilities

Demand for underground utilities in Ajax (Durham Region) comes mostly from 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.

Activity clusters in the Clements and Bayly industrial corridor, Salem Road business park, and the 401 employment lands. Harrowgate Group regularly builds underground utilities for Ajax clients like manufacturers, distributors, healthcare, and the Town of Ajax, each project carrying its own site and requirements.

What Ajax conditions mean for the project
