About Us
read moreIn the 1880s John McQuillan discovered a deposit of limestone on his small farm at Colinwell, so named because of the spring well which rises at our site on on Colin Mountain. In 1888 he built kilns and began to process the quarried limestone by burning it with coal to form calcium oxide, a widely used fertiliser and mortar ingredient of the time. In the years that followed his sons and grandson began quarrying the basalt stone, which also lay in the area, to produce aggregates for road construction etc, for the manufacture of concrete blocks.
