Doddington Specification
General
The quarry is near the golf course in the village of Doddington between Wooler and Berwick-upon-Tweed. It has been worked regularly since at least 1950 and probably for more than 150 years before this. There are also old workings nearby. It has good reserves of stone.
Petrography 
Doddington sandstone is from the Fell Sandstone Group of the Carboniferous Limestone. It is a fine- to medium-grained stone, speckled, light to deep purplish pink in colour with occasional rust coloured markings. Stone can be obtained from three or four different faces each 9 – 12m deep with about 6m of overburden. It is generally supplied at depths of 1.2m on bed.
Expected Durability and Performance 
It is important that the results from the individual tests are not viewed in isolation. They should be considered together and compared to the performance of the stone in existing buildings and other uses. Sandstones from the Carboniferous series are traditionally acknowledged as generally being a very durable building and paving stone and have been used extensively in many towns and cities in the UK. Doddington sandstone appears to be a durable stone that is not effected by acid rain or air pollution. The very low weight lost in the harsh saturated sodium sulphate crystallisation test indicates good resistance to salt damage in very severe environments (for example in coastal locations or from de-icing salts) but the most recent tests showed a large weight loss perhaps indicating variability in the stone; the results suggest that the stone would have good frost resistance. The compressive strength of the stone is typical of the range for sandstone. The flexural strength is towards the lower end of the range for sandstones and if used for paving then the units may need to be thicker than those for some other sandstones. The abrasion resistance is comparable with many paving stones and should be suitable for use in heavily trafficked areas.
Overall, should be suitable for use in most aspects of construction including flooring, paving, load bearing masonry and cladding.
