Building on the tradition of manufacturing masonry products since the 1880s.

In 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 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 masonry products.

Today Colinwell is owned and managed by Phelim and Donal McQuillan, great grandsons of our founder, who continue the family tradition of manufacturing quality construction products while remaining innovative and flexible to customer and market needs.

The company has been producing the finest quality concrete products for over 130 years.
