Sand and gravel
Hanson is the UK's leading producer of sand and gravel from a network of over 30 quarries and a marine dredging business. Much of the material we produce is used in the manufacture of ready-mixed or precast concrete at our own plants. We also sell sand and gravel to other precast and ready-mixed concrete manufacturers. We produce specialist and industrial sands for a range of uses from glass making and water filtration to horticulture and leisure.
Hanson can supply a wide range of aggregates which are suitable for use as fill materials in a variety of construction applications.

Hanson can supply railway ballast, generally this consists of a durable and wear resistant igneous rock, such as granite, with large (40-50 mm size) angular pieces that lock together. Because of the way igneous rock is formed it is highly resistant to pressure and does not break easily. Our railway ballast is produced in accordance with BS EN 13450 (Aggregates for Railway Ballast) and is backed up by rigorous quality control testing by our technical team.
There are no flat rates for aggregates per tonne, as a number of factors can affect the cost –
including the intended application, type and quantity of the aggregate you require. The first step is to work out what type of aggregate you need, along with how much you need for your project, while considering any special requirements, for example, the polished stone value (PSV) needed if using the aggregate for use in asphalt. Our are on hand to help, so feel free to reach out to us for assistance at any stage in your planning process.
Aggregate sizes most commonly used for road construction and maintenance include; 125mm or below for foundation or capping layers and typically 31.5mm or below for use in granular sub bases (typically 31.5mm or below) However, asphalt typically contains aggregates between 31.5mm and 6mm while, in surface dressing, used to extend the live of the road carriageway, aggregate sizes typically used are between 4mm and 10mm.
There are various types of aggregates used in building construction that can be categorised into coarse and fine aggregates or a mixture of both, and include aggregate materials such as crushed rock, sand and gravel or secondary recycled aggregates. Hanson is one of the UK’s largest suppliers of bulk construction aggregates, from fill materials to aggregates that can be used in cement, concrete and precast concrete.
The most common solution for building solid foundations is to use concrete that includes gravel aggregates. For most domestic concrete footings, such as single-storey extension foundations, 100mm of base aggregates is adequate.
