Managing our land

Tarmac is a proud custodian of over 60,000 acres of land. This stewardship and 80+ sites designated as having high biodiversity value is a key aspect of our whole life approach. We recognise our duty to manage these assets responsibly and to enable positive outcomes for our business, the community, and future generations

Working in partnership with local authorities, landowners and others, we source and extract aggregates to support the development of infrastructure and construction projects across the UK.

In our efforts to minimise environmental impacts through careful planning and responsible working we are committed to gaining and maintaining the support of local communities through ongoing consultation and engagement.

Our commitment is the right use of the asset at the right time. We collaborate with development partners to create vibrant new communities, comprising family homes, community, and commercial spaces, as well as manage numerous quarries and parkland, such as the 400-hectare Panshangar Park in Hertfordshire, which like much of our restored parkland, is an award-winning haven for both people and wildlife.

We ensure the land we work on is operated efficiently and at the end of its construction phase is not only restored but regenerated. Creating a positive, lasting legacy.

We are committed to building a zero harm culture that prioritises people's health, safety and well-being, and targets continuous improvement.

Health & Safety

We work hard to operate a safe and healthy business. Our ambition is to realise continuous improvement for all our employees and contractors.

This approach to safety extends across our supply chain and to every aspect of our business - from the way we manage sites and the way we train and equip our employees and contractors - to the safety features we innovate across our fleet to protect road users.

We’re proud to work with experts in the field of Health and Safety, such as the British Safety Council and The Health and Safety Executive and are also one of the founding partners of a mental health programme for people working in the construction sector called Mates in Mind.

We also operate our National Skills and Safety Park. Dedicated to operational onboarding, professional operational training, assessments and health and safety learning. This industry-leading facility demonstrates our ongoing commitment to a culture of safety excellence.
