Product Overview
100mm solid dense concrete block with a compressive strength rating of 7.3N/mm², measuring 440mm x 215mm x 100mm.
Produced from a dense aggregate mix of cement, sand, and crushed stone, it delivers high load-bearing capacity and long-term durability.
The block’s mass provides additional acoustic and fire performance, while its standard dimensions ensure compatibility with UK masonry systems.
Suitable for structural internal and external walls, it is a reliable choice for foundations, partitions, separating walls, and cavity wall inner leaves.
Features & Benefits
- 7.3N/mm² compressive strength: Strong enough for load-bearing walls in houses, extensions, and commercial projects.
- Dense aggregate composition: Offers resilience against impact, abrasion, and physical wear.
- High thermal mass: Contributes to regulating internal temperatures by absorbing and releasing heat slowly.
- Effective sound insulation: Density reduces airborne sound transmission, making it suitable for party walls.
- Non-combustible (Euroclass A1): Provides inherent fire safety, meeting building regulations.
- Secure base for fixings: Solid block allows safe anchoring of heavy fittings when used with appropriate fixings.
- Frost resistance: Manufactured to withstand cycles of freezing and thawing in external walling.
- Standard size 440mm x 215mm x 100mm: Easy to integrate into traditional UK brick and block wall construction.
Please Note: Orders requiring a pallet will incur a refundable pallet charge of £20 ex VAT per pallet. Our customer service team will confirm if this applies to your order.
Applications
- Can be used with foundation walling: Standard choice for below-DPC applications such as foundations and sleeper walls.
- Internal load-bearing walls: Suitable for supporting upper floors, ceilings, and roof structures.
- Separating walls: Provides acoustic insulation and fire resistance between dwellings.
- External walls: Forms the structural inner leaf of a cavity wall or a solid wall when finished with render, cladding, or other protective systems.
Installation Guidance
- Mortar bedding: Lay blocks on full, well-compacted mortar beds to achieve strength and stability.
- Joins and bonding: Stagger vertical joints for wall strength; ensure full mortar coverage on perp ends.
- Finishing: Blocks should be plastered, drylined, rendered, or clad externally to protect against weather exposure.
Compliance & Performance
- Compressive strength 7.3N/mm²: Verified to meet load-bearing design requirements for domestic and commercial walls.
- BS EN 771-3 compliance: Manufactured to European standards for aggregate concrete masonry units, covering strength, density, and durability performance.
