McQuillan Quarries have been associated with high quality materials and service for generations. This tradition has ensured that we are now leading suppliers of blacktop products, high PSV aggregate and sub base materials throughout GB and Ireland today.

Blacktop and Bituminous Products

Our two asphalt coating plant locations outside Belfast and Dromore Co. Down have state of the art manufacturing facilities allowing us to supply our own contracting division whilst comfortably servicing a public market for any blacktop material needs. With materials testing labs at both depots, we ensure the supply of quality products that meet British and European standards.


Due to our locations we are suited to provide materials to sites in the greater Belfast area, Lisburn area and across NI.


At Edentrillick Quarry we extract the high PSV (60+) Co. Down Gritstone which is primarily used in our surfacing materials.

Quotes for export to GB and ROI are available upon request.


Recycled Aggregate

We are capable of producing a range of recycled materials for both bound and unbound applications in accordance with the WRAP (Waste & Resources Action Programme) Quality Protocol for the production of aggregates from inert waste.

Quick Surf

We are now producing a deferred set or cold lay macadam material available in bulk and bagged orders. We have designed our material with an additive that allows for quick installation with prolonged durability expected when compared with similar products on the market. For all enquiries, contact our Budore depot.


We also now provide a range of sizes of bagged and bulk pre coated chips. We manufacture traditional black at both of our depots, with also a range of Red Pre Coated Chips manufactured at our Budore Quarry.
