Available here at Travis Perkins, engineering bricks come in two strength classes – Class A (the stronger class) and Class B. Engineering bricks are used in construction for their strength and ability to withstand frost and wet conditions. They are not to be used for aesthetic purposes. Their main uses would be for building foundations, retaining walls, DPCs, and underground tunnels such as sewers. As well as the two strength classes, we stock both red and blue engineering bricks in our range. It’s due to this wide selection why we are the largest supplier of building materials to the building and construction industry in the UK.
