65mm Engineering Blue Bricks Class B

Our 65mm Engineering Blue Bricks (Class B) are engineered for technical performance rather than pure aesthetics. These bricks are fired at extremely high temperatures, resulting in a dense, semi-vitreous body that offers exceptional compressive strength and incredibly low water absorption. This makes them the go-to choice for any application where the brickwork will be under heavy load or in constant contact with moisture. Each brick measures the standard UK size of 215mm x 65mm x 102.5mm, ensuring they integrate perfectly with standard mortar joints and other common brick types. Because of their Class B rating, they are highly resistant to frost and chemical attack, making them essential for groundwork, damp-proof courses (DPC), and retaining walls. Whether you need a single brick to finish a small garden plinth or a full pallet of 400 for a major extension or civil engineering project, we provide flexible quantity options to suit your needs. Superior Strength: Class B rating ensures a compressive strength of 75N/mm² or greater, ideal for load-bearing structures. Low Water Absorption: With a water absorption rate of less than 7%, these bricks effectively resist rising damp and water ingress. Extreme Durability: Fully frost-resistant (F2 rated), making them suitable for severe weather exposure and below-ground use. Standardised Sizing: Dimensions of 215mm x 65mm x 102.5mm ensure compatibility with existing masonry and coursing. Versatile Quantities: Available as individual units for repairs or in bulk pallets of 400 for maximum value on large builds.
