|Ground Pozzulanic Material.
The use of pozzulans dates back to Roman times, when crushed brick was added to lime cements to create a stronger setting formula. We have found that our brick has this pozzulanic quality, and it has been tested by.
GPM comes in two basic colours – red from our own red bricks, and buff from bricks made on our site from an alternative source giving the buff/yellow/pink bricks we can produce where white work is required. We can produce fine (particle size), medium or coarse and this is supplied in 25kg bags as required.
