We are Part of the Thomas Armstrong Group
Concrete Common units also known as ‘frogged bricks’ are coursing bricks which are designed to work in conjunction with Thomas Armstrong’s Dense Concrete Blocks for applications above and below damp-proof course (DPC).
Our concrete coursing bricks are designed for infill around openings and adjustment of coursing heights conveniently reducing the need to cut down whole blocks, resulting in saving time and waste. All Concrete Common Bricks are frogged and are manufactured using high-quality, locally sourced raw materials.
Concrete Common bricks possess low drying shrinkage, very high load-bearing capacity so are ideally suited for accepting renders and finishes. Their use ensures a continuity of material type throughout the build helping to avoid differential movement problems and maximise thermal performance.
Concrete Common bricks are manufactured to BS EN 771-3 and are ISO 9001 Quality Assured, ISO 14001 Environmentally Certified and hold BES 6001 ‘Excellent’.
