Aggregates and Asphalt

Cormac’s quarry and asphalt business, located in West Cornwall provides a comprehensive range of aggregates and asphalt materials throughout the South-West to support the construction industry.

Cormac’s quarry produces a 57PSV Granite aggregate with capability to produce a range of materials including single size aggregates for asphalt, concrete production and surface dressing. In addition to this, through a two stage crushing and screening process we are also able to supply a full range of road construction materials. Our asphalt capabilities can provide our customers with a range of base course, binder course and surface course mixtures utilising 57 to 68PSV.

Through significant investment, we are now producing low temperature asphalt mixes to further compliment our existing product ranges. The investment in this technology provides carbon savings of approximately 15% which can be further increased through the use of our RAP processing plant. The introduction of both RAP and Low temperature asphalt further demonstrates Cormac’s commitment to sustainable construction.

Cormac have been supplying rock armour for use in coastal protection projects across the southwest for many years and with our fully integrated design capabilities are able to provide fully bespoke design, supply delivery and installation to our clients. Through partnership we are now also able to ship these materials to locations across the UK and Europe where required.    


Cormac’s commitment to support carbon reduction throughout its operation has seen significant investment including: the purchase of the latest construction machinery, introduction of biofuels across our business and investment to allow the production of low temperature and low carbon asphalt.

More recently we commenced construction installing a solar farm, to further support the renewable energy requirements across the quarry and introduced a foam mix alternative to compliment our asphalt and aggregate offering. Our foam mix production and laying capabilities offer further carbon savings to our clients.
