Stoke Ground Bath stone – base bed
Stoke Ground Base Bed is a light buff / grey slightly open grained limestone, with small intermittent shell deposits. It is the ideal stone for exposed and weathering areas such as cornices, coping and string courses where you want the aesthetic qualities of Bath Stone but also need to achieve enhanced durability.
Petrographic Description and Mineral Examination
Stoke Ground Base Bed is an open grained, oolitic limestome with small intermittent shell deposits from the Great Oolite of the middle Jurassic age. Light Buff/Grey in colour which mellows with age, Base Bed is suitable for all types of masonry detailing, cladding, ashlar walling, flooring, fireplaces and building stone.
Stoke Ground Base Bed is traditionally acknowledged as a durable limestone and its performance when used in exposed and weathering areas such as cornices, copings or string courses make it an excellent choice where its working qualities are required.
Base Bed is extensively used in restoration work, commercial and residential new builds throughout the UK and the limestone is mined at approximately 15m below ground and relatively easy to access.
