Dense Concrete Blocks

Our Breedon Cellular Blocks are a type of concrete masonry unit that has uniformly distributed, voids (cells) within their structure. These cells are created during manufacturing by casting the blocks with internal cavities, typically without compromising the outer shell of them.

Key Benefits:

• Lightweight: The air pockets reduce the overall weight compared to solid blocks, making them easier to handle and lay.
• Good Insulation: The internal air pockets improve thermal and sound insulation, helping with energy efficiency and noise reduction.
• Load-Bearing: Despite being lighter, many cellular blocks maintain sufficient strength for load-bearing applications, especially in residential and low- to mid-rise buildings.
• Improved Workability: Easier to cut and chase for services (e.g. pipes, conduits) compared to denser solid blocks.

Our Breedon Foundation Blocks are high-strength, load-bearing masonry units specifically designed for use in foundation and sub-structure applications, where strength, stability, and durability are critical. These blocks can be 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 and high strength allow for fewer courses, speeding up construction and reducing labour costs.
• Moisture Resistant: Dense concrete and low porosity make them ideal for use in wet or below-ground environments.

Our Breedon 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 fine aggregates 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 when used in exposed masonry walls.
• High density and 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.

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

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.

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.
