About the Bath Plant

The Bath Cement Plant has been producing materials for the construction industry at its current location since 1973. The plant is located on the north side of Highway 33, approximately three kilometres west of Bath, Ontario and 25 kilometres west of the City of Kingston.


The story of Bath cement begins in our quarry just north of the plant. There, Lafarge employees quarry limestone, which is crushed and carried to the plant by a conveyor system 1.5 kilometres long.


At the plant, the limestone is mixed with other raw materials and heated to over 1450 degrees Celsius – a temperature a quarter that of the surface of the sun – in the plant’s kiln where it becomes clinker. When the clinker emerges from the kiln, it is cooled, mixed with gypsum, and ground into a fine powder known as portland cement.


Cement is shipped from the Bath plant to construction projects throughout Lafarge’s Great Lakes Region by truck, rail, and a fleet of ships.
