Oolitic limestone originating from the Great Oolite formation of Jurassic age.

Petrography

Principally formed from micritic ooids in a micritic matrix with small shells, the stone is medium to fine grained with no clay minerals present.

Durability & Weathering

Westwood Ground Bath Stone has traditionally been used where its working qualities, texture and rich colour have been required. Although one of the softer building limestones, it weathers well, especially when stonework is detailed to offer maximum protection to rainwater and rainwater run-off.

Based on current research, it seems likely that the stone will weather at a rate of between 3 and 4 millimetres per 100 years, but it could be greater in severe exposures or on the edges of stonework.
