'Hanson UK - building products and construction materials
Hanson is one of the world's largest suppliers of heavy building materials to the construction industry. We produce aggregates (crushed rock, sand and gravel), ready-mixed and precast concrete, asphalt and cement-related materials and a range of building products including concrete pipes, concrete pavers, tiles and clay bricks.
We are part of the HeidelbergCement Group, which employs 65,000 people across five continents. HeidelbergCement is the global leader in aggregates and has leading positions in cement, concrete and heavy building products.
Hanson's UK business is split into four business lines - aggregates and asphalt, concrete, building products and cementitious - which together operate around 400 manufacturing sites and employ some 6,800 people.
Our aggregates and asphalt division produces sand and gravel from the land and sea, crushed rock and asphalt for road surfacing. Total aggregates production in 2007 was around 32 million tonnes, along with 3.5 million tonnes of asphalt. The division also operates a national contracting business specialising in road surfacing and infrastructure work.
Our concrete division is one of the UK's largest suppliers of ready-mixed concrete from a network of some 220 fixed and site-based plants.
Our building products division has48 production sites and is the largest producer of clay bricks and aircrete blocks in the UK. Its product range also includes wall cladding systems, aggregate blocks, concrete and clay pavers, decorative rocks and stones, bagged products, concrete flooring and precast concrete products. The division includes the specialist brick and block laying contractor Irvine-Whitlock.
The cementitious division combines Castle Cement, a leading producer of Portland cement, and Civil and Marine, which makes ground granulated blast furnace slag (GGBS) - a cement replacement in ready-mixed and precast concrete. Castle Cement provides around a quarter of the total UK cement market from three works. Castle also has its own hydrocarbon recycling business SRM, which produces alternative fuels for the cement kilns.'
