Blue Engineer Perforated 73mm K20973p

Engineering bricks are specified for their physical characteristics and not their appearance. They have high compressive strength and low water absorption and are classified only by these properties. Their use for facing work should be avoided, as they are not subject to the same level of inspection for surface irregularities or colour variation as a facing brick. Where aesthetic performance is a major consideration, facing bricks should be used.
