Product Overview
140mm solid dense concrete block with a compressive strength of 7.3N/mm², measuring 440mm x 215mm x 140mm.
Made from dense aggregate concrete, this 140mm block is built to handle the demands of structural walling and flooring.
Its extra width provides added stability over 100mm blocks, while the heavy mass improves sound reduction and helps regulate temperature.
Versatile in use, it performs well in cavity walls, solid external walls, and as an infill block in beam-and-block floors. With natural fire and moisture resistance, it offers a dependable solution for projects of all sizes.
Features & Benefits
- 7.3N/mm² compressive strength: Certified strength for use in structural walling, partitions, and flooring systems.
- Dense aggregate composition: High-density mix resists impact, abrasion, and mechanical wear.
- High thermal mass: Helps moderate internal temperatures by absorbing and slowly releasing heat.
- Sound insulation properties: Mass reduces airborne sound transmission, suitable for separating walls.
- Non-combustible (Euroclass A1): Provides fire safety and compliance with building regulations.
- Water resistant: Performs reliably in damp conditions when used within a designed walling system.
- Strong fixings: Solid core allows safe anchoring of heavy items with the right wall fixings.
- Standard size 440mm x 215mm x 140mm: Compatible with conventional UK brick and block walling systems.
Please Note: Blocks are delivered palletised. Orders requiring a pallet may 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 cavity wall construction: Provides strength and stability as an inner or outer leaf.
- Solid wall construction: Suitable for robust load-bearing walls in residential and commercial builds.
- Beam-and-block flooring systems: Acts as a dense infill block for durable suspended floors.
- Internal partitions: Provides strength, fire resistance, and sound insulation for separating walls.
Installation Guidance
- Mortar bedding: Lay blocks on full mortar beds to ensure stability and effective load distribution.
- Bonding pattern: Stagger vertical joints for structural integrity and wall strength.
- Handling and placement: Blocks are heavy; use appropriate manual handling methods or mechanical aids.
- Finishing: Accepts render, plaster, cladding, or drylining depending on application.
Compliance & Performance
- Compressive strength 7.3N/mm²: Provides certified load-bearing performance in structural walling and flooring.
- BS EN 771-3 compliance: Manufactured to European standards for aggregate concrete masonry units, covering strength, durability, density, and dimensional accuracy.
