Ibstock Chesterton Class B Red 65mm Engineering Brick Pack of 500
The Ibstock Red Engineering Class B Brick is a high-strength, low water absorption brick designed for structural applications. Manufactured using a perforated, wirecut process, it offers exceptional compressive strength, making it ideal for foundations, retaining walls, and other load-bearing projects. Its low water absorption reduces the risk of frost damage and enhances durability. As an engineering brick, it is specified for its performance rather than its appearance, meaning it is not intended for facing work. Where aesthetics are a priority, a facing brick should be used instead. Please note this product is produced in Ibstocks Chesterton factory and is therefore more suited to counties in the Midlands & South
