Lightweight Concrete Blocks

Breedon Lightweight Foundation Blocks are high strength, load-bearing masonry units specifically designed for use in foundation and sub-structure applications, where versatility, strength, stability, and durability are critical. These blocks are commonly used below damp-proof course (DPC) level to support the load of the structure above.

Key Benefits:

• High compressive strength: Typically available in strengths such as 7.3N/mm² or higher, capable of supporting significant structural loads.
• Thick and wide profiles: Usually wider than standard wall blocks (commonly 300mm wide) to match wall thickness or to reduce the number of courses below ground.
• Solid construction: Most foundation blocks are solid to provide maximum load-bearing capacity and resistance to moisture ingress.
• Time and cost-efficient: The larger size, lighter weight and high strength allow for fewer courses, speeding up construction and reducing labour costs.

Available in a range of strengths and sizes, please contact your local sales office for further details or alternatively, down load the Breedon Blocks brochure form our web site.

Breedon Lightweight Paint Grade blocks are specially manufactured concrete masonry units with a smoother, more uniform surface finish that is designed to be left exposed and painted directly, without the need for plastering or rendering.

Key Benefits:

• Smooth face finish: Made with lower density aggregates for versatility and tighter manufacturing tolerances to achieve a clean, even surface suitable for painting.
• Ready for decoration: Requires minimal surface preparation before applying paint – typically just cleaning and priming.
• Consistent appearance: Uniform texture reduces visual imperfections.
• Strength: Like standard dense blocks, they are structurally sound and suitable for load-bearing or non-load-bearing applications.
• Durable and long-lasting: Offers the strength and durability of a dense block, with an attractive finish once painted.
• Aesthetic versatility: Suitable for a range of decorative finishes (matt, gloss, textured paints, etc.), making it ideal for internal feature walls or exposed blockwork in commercial or industrial settings.

Breedon Lightweight coursing and spacing accessory units are used to help achieve correct wall heights, alignments, and modular consistency without cutting standard blocks.

Lightweight coursing accessory units are smaller-height concrete blocks used to:

• Adjust wall height incrementally, especially to meet specific floor-to-ceiling dimensions
• Maintain consistent coursing with standard block and brick modules (often used at window heads, sills, or top of walls). For example, if standard blocks are 215mm high, but you need to line up with brickwork (which is typically 65mm high per course), you can use coursing blocks to make up the difference cleanly.

Breedon Lightweight Spacing accessory units are designed to help:

• Fill small gaps in wall runs where standard-sized blocks do not perfectly fit
• Maintain proper wall alignment and coursing when obstacles (e.g., pipework or openings) require dimensional adjustments
• Support dimensional tolerance during construction without cutting blocks on-site

They are often shorter in length or width and are sometimes referred to as closers, partial blocks, or infill blocks.

Key Benefits:

• Reduce or eliminate the need for cutting blocks on site
• Improve build speed and accuracy
• Ensure clean alignment with architectural or structural features
• Help achieve modular compatibility between block and brickwork
• Easy to handle and install
