This is a mostly shelly stone, with a slightly open texture, but does not have the openness of Roach.
Coombefield shelly whitbed is exceptionally durable due to the high shell content and can be used in more exposed area’s. We have sufficient stock of this Portland stone on the ground for most projects
It is worth noting that the durability provided by the shell reduces the use for heavily detailed or carved work, instead it is very suitable for ashlar, paving and copings.
