Coursing bricks are normally used as infill or bridging units in walls, foundations and all types of construction. They minimise waste and reduce the need for cutting standard size blocks. We stock 2 strengths grades of block, 3.6N and 10N. Coursing Bricks are available for delivery or can be collected in store in our Peterborough, Huntingdon and Corby branches. If you still need some assist, please call into your local branch for advice.
