Tarmac is a leading UK building materials and construction solutions business, supplying products and services for infrastructure, commercial and residential projects. As part of CRH, a global provider of building materials solutions, Tarmac combines local manufacturing and technical expertise with the wider capability of an international group. 

Tarmac’s cement manufacture is built on more than a century of materials innovation and a nationwide production footprint that supports consistent, high-quality supply across the UK. With manufacturing sites operating as part of a wider CRH supported network, the business produces a full range of factory‑made and blended cements including lower carbon options such as CEM II and specialised formulations to help meet the performance needs of modern construction.

All products are produced to the European BS EN 197‑1 standard, ensuring reliability, quality assurance, and suitability for applications ranging from ready‑mixed concrete to precast and geotechnical engineering solutions.

The impact of this manufacturing capability is seen across major UK infrastructure, where national logistics and supply networks enable timely delivery to major projects such as infrastructure, energy installations, and structural developments.

Our founders patented Portland cement over 125 years ago. Today Tarmac continues this legacy as an essential nationwide supplier of high‑quality cement materials that help drive the UK’s construction and infrastructure growth.
