Compiled September 1999
This data sheet was compiled by the Building Research Establishment (BRE). Where possible, data collected in earlier surveys has been used to help interpret the test results. The data sheet was compiled in September 1999 using the results of tests carried out to the proposed European Standards. 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 Stanley’s Quarry and does not represent an endorsement of the stone by BRE.
The quarry is located within the Northwick Park Estate and is accessed from the B4061 (Chipping Campden road) off the A44. The quarry has been in production for more than 100 years but has expanded rapidly over the last 15 years. The stone occurs in distinctive colours, known Beds 1 to 4. Good reserves are available. The maximum blocks size at the quarry is 2-00mm x 2000mm by 1000mm height on bed with the largest sawn slabs 600 height on bed.
The stone is an oolithic limestone and the beds are part of the Jurassic Great Oolite Series
Expected Durability and Performance
It is important that the results from the sodium sulphate crystallisation tests are not viewed in isolation. They should be considered with the results from the porosity and water absorption tests and the performance of the stone in existing buildings. Stone from the Cotswold region is traditionally used as building stone in the region and increasingly in many other towns and cities in the UK. The high water absorption and porosity indicate a very open stone that will have good resistance to weathering. The sodium sulphate crystallisation result also indicates that the stone will have good resistance to salt damage and that it will perform well in all but the most exposed locations where it may it may require some extra protection or careful design and detailing to shed water. The strength is towards the lower end of the range for limestones but the performance should satisfactory if the relevant British Standards are followed.
