Castle Construction Products

At Castle we manufacture high quality concrete blocks at our 4.5 acre production plant located at Cardiff docks. As members of the British Precast and Concrete Block Associations, our concrete products are manufactured to the highest standards. Through careful sourcing of recycled aggregates our products are very competitively priced. We also manufacturer high quality dense concrete blocks, using a mixture of both virgin and recycled aggregates. We operate a robust quality management system certified to ISO9001, which ensures the highest quality 7.3N and 10.4N blocks are produced. We manufacture blocks in both 100mm and 140mm widths. We are also accredited to ISO14001 and our blocks are CE marked for quality. Coursing bricks are also available if required. We passionately believe in top level customer service and flexibly, to help make our customers lives easier.
