Delta Grinding Facility Project

Heidelberg Materials Canada Limited is proposing to construct, operate and decommission a grinding facility with a marine terminal adjacent to its existing cement plant facility located on Tilbury Island in Delta, British Columbia. As proposed, the Delta Grinding Facility Project would produce up to 650,000 tonnes of supplementary cementitious material per year when fully operational, and would have an operational life of at least 40 years.

 

Please note that the proponent for this project was previously Lehigh Hanson Materials Limited.
