Compiled November 1997, updated June 2000
This data sheet was compiled by the Building Research Establishment (BRE)., The data sheet was compiled in November 1997 and updated in June 2000 using BRE test results and data collected in earlier surveys. The work was carried out by BRE as part of a Partners in Technology Programme funded by the Department of the Environment, Transport and the Regions and Blockstone Ltd and does not represent an endorsement of the stone by BRE.
The quarry is near Kirk Patrick Fleming, near Annan in Dumfries and Galloway. It was open in the 19th century and records show that it has been used for buildings since at least 1890.
Cove Red Sandstone is a sandstone is from the New Red Sandstone of Triassic age. It is a fine-grained stone, red/brown in colour with varying bed definitions. The average block size is 2000mm x 1000mm x 400mm.
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 New Red Sandstone are traditionally acknowledged as generally being a very durable building stone and have been used extensively in many towns and cities in the UK. Cove Red Sandstone appears to be a durable stone that is not effected by acid rain or air pollution. Most sandstones have good frost resistance. The failure in the harsh saturated sodium sulphate crystallisation test indicates susceptibility to salt damage (for example in coastal locations or from de-icing salts). The compressive strength of the stone is towards the lower end of the range for sandstones but is comparable with that for UK limestones.
Overall, Cove should be suitable for use in most aspects of load bearing masonry and cladding but should not be used in areas where a long service life is needed in locations with a high salt concentrations.
