Solid Dense Concrete Blocks | 100mm 7.3N

Solid Dense 140 mm 7.3 N Concrete Blocks deliver exceptional structural performance for demanding applications. Being fully solid, they are significantly heavier and more robust than cellular, aircrete, or medium‑density blocks, making them ideal for walls where high load‑bearing capacity, durability, and stability are required. You’ll commonly find them in separating walls, beam‑and‑block flooring infill, boundary walls, and any project demanding maximum strength and resilience.

Produced from Portland cement, sand, and crushed stone, these blocks offer a dense profile that provides excellent sound insulation and inherent fire resistance. Their rough‑textured faces key easily to plaster, render, or dry‑lining systems, while low water absorption improves frost durability and longevity. Fully UKCA marked to confirm compliance with modern building standards, these blocks are suitable for internal or external use, above or below DPC, and in both cavity and solid wall construction.

Key Features & Benefits:

• High Strength and Durability: With a compressive strength of 7.3 N/mm², this block is designed for heavy-duty applications, ensuring long-lasting structural integrity.
• Acoustic Performance: The high-density nature of this block helps significantly reduce noise, making it a great choice for both residential and commercial projects where sound insulation is important.
• Versatile Applications: Suitable for both internal and external walls, as well as above and below ground use, including in block and beam flooring systems and foundation walls.
• Fire and Water Resistant: Offers excellent fire resistance, providing added safety in your building. It also features low water absorption, making it a reliable option for areas exposed to moisture.
• Ease of Use: Its standard finish and solid construction make it easy to handle, cut, and lay, speeding up installation and improving overall efficiency.
• Long-Lasting Performance: The block’s strength, durability, and resistance to fire and moisture ensure reliable performance over the long term, even in challenging conditions.
