140mm Solid Dense 7.3N Concrete Block - Pack of 72

Product Overview

Purchasing 100mm Solid Dense 7.3N Concrete Blocks as a pack ensures your construction projects run smoothly and cost-effectively. When you choose packs of 72:

• Better value for money: Buying larger quantities reduces the cost per block, giving you a stronger return on investment.
• Less risk of damage: Bulk packs are securely stacked and delivered, minimising the chances of individual blocks breaking in transit.
• Lower overall costs: Ordering small amounts regularly often means extra surcharges and higher transport fees. Stocking up avoids this.

Features & Benefits

• Maximises efficiency & productivity: Keeps workers supplied with durable blocks, cutting downtime on site.
• Consistency across projects: Ensures every section of your build uses the same strength and density of block.
• Avoids delays: With a ready supply on hand, you won’t be held back by lead times or last-minute shortages.
• Saves time on site: Having blocks ready to go speeds up the build process, making life easier for the whole team.

Applications

• 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 essential 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.
• Piers and columns: Used to build structural piers to support heavy beams, lintels, or rolled steel joists (RSJs), and to reinforce door and window openings.
• Retaining walls (non-structural): Commonly used for small-scale garden landscaping, such as creating raised flower beds or low garden terraces.
• Infill panels: Frequently used as fire-resistant, secure infill between steel or timber frame members in industrial or commercial builds.
• Firewalls: Utilised to create compartment walls in garages or workshops to effectively slow the spread of fire.
• Garden and boundary walls: High compressive strength provides the necessary structural mass for freestanding walls and external boundaries up to 1.2m in height.
• Fireplace and chimney construction: Non-combustible A1 rated material ensures suitability for chimney breast rebuilding and fireplace surrounds in compliance with Building Regulations Part J.
• Acoustic separating walls: High density material weighing approximately 2000kg/m³ provides the required sound attenuation for internal partitions in multi-occupancy dwellings to meet Part E requirements.

Installation Guidance

• Lay with appropriate mortar: Apply a consistent bed and perpend of mortar to ensure structural integrity and load distribution.
• Ensure level bedding: Use a spirit level regularly to maintain plumb and level courses throughout the wall height.
• Apply correct ties: When constructing cavity walls, use appropriate wall ties at specified centres to secure the inner and outer leaves.
• Handle with care: Although robust, use mechanical handling where possible to maintain the integrity of the blocks and prevent site-based damage.

Compliance & Performance

• Compressive strength: 7.3N/mm² structural rating.
• Fire resistance: Non-combustible material; provides reliable compartmentation.
• Acoustic performance: High-density mass assists in noise reduction between rooms and dwellings.
• Pallet Charge: A pallet will incur a refundable pallet charge. Our customer service team will confirm if this applies to your order.
