440 x 215mm Concrete Block – Topcrete Solid Standard 7.3N

Our Topcrete Standard Dense Blocks are the “heavyweights” of the construction world. Manufactured from high-quality crushed aggregate and cement, these solid blocks are engineered for applications where strength and density are non-negotiable. With a robust 7.3N/mm² compressive strength, they are significantly stronger than lightweight aircrete or medium-density blocks. These blocks are ideal for the construction of load-bearing internal and external walls, as well as the outer leaf of cavity walls when a render or cladding finish is applied. Due to their high mass, Topcrete blocks provide exceptional acoustic insulation, making them perfect for separating walls in residential buildings (meeting Part E building regulations). They also offer superior thermal mass, helping to regulate building temperatures by absorbing heat during the day and releasing it at night. Built to last, these dense blocks are highly resistant to moisture and physical impact, making them suitable for use both above and below the damp-proof course (DPC). High Compressive Strength: 7.3N/mm² rating ensures these blocks can support significant structural loads, including multiple storeys. Superior Sound Proofing: High density provides a natural barrier against noise, ideal for busy households or terraced properties. Total Durability: Resistant to fire (Class A1), frost, and moisture, ensuring a long lifespan in any environment. Excellent Thermal Mass: Helps improve the energy efficiency of a building by managing heat fluctuations. Standardised Sizing: 440mm x 215mm x 100mm dimensions ensure compatibility with all standard UK masonry and ties.
