The Mastic Asphalt Council

The Mastic Asphalt Council (MAC) is the trade association for the UK mastic asphalt industry. MAC represents more than 90 companies – including mastic asphalt manufacturers, the contractors responsible for its installation, and associated suppliers of equipment and services. Top quality products, design and workmanship are fundamental to the Mastic Asphalt Council. MAC membership is only open to those manufacturers and contractors that can satisfy the stringent quality requirements. These strict membership requirements enable MAC to justifiably claim that it represents the UK’s top 70 mastic asphalt contractors, as well as leading manufacturers. That’s why you should always look for the MAC logo – only MAC members can use this mark of quality.


The MCRMA was formed in 1990 to support the systems manufacturers in the emerging metal cladding and roofing industry. Since then MCRMA has evolved to encompass the needs of component manufacturer suppliers, system installers, independent roofing and cladding inspectors plus industry support services providers, all providing independent building envelope solutions for metal-based roofing and cladding systems, products and services.

Each month thousands of contractors and consultants (suppliers) apply for work with public and private sector organisations (buyers). To win work, they must meet the buyer’s health and safety standards.  Assessing suppliers health and safety competence is usually a lengthy and time consuming process.
