About Craig Yr Hesg

Craig yr Hesg quarry in the Taff Valley, near Pontypridd is a nationally important source of premium quality blue pennant sandstone for road surfacing. The stone has very high skid resistance, making it ideal for the top surface of roads. It is widely used throughout South Wales and Southern England and has gone into a number of major projects including  the Heathrow Airport runway and the M25. The quarry also supplies stone for use in concrete and for other construction projects. Reserves are running low so Hanson has submitted a planning application to extend the existing workings into land to the north-west currently used for grazing. If permitted, the extension area would release a further 10 million tonnes of rock.

The quarry habitats include pockets of semi natural woodland, small pockets of heathland, rock and scree, open habitat on previously disturbed ground and quarry benches and tips that are regenerating naturally to woodland.  Barn owls and peregrine falcons use the site for breeding.

Quarry history

Quarrying began at Craig yr Hesg in around 1885. At one stage more than 100 people worked at the site. Today the quarry employs 16 people directly while a further 30 depend upon it for their livelihood.
