Our 100mm solid dense 7.3N concrete blocks are the perfect choice for construction projects that require exceptional strength and reliability. Engineered for maximum versatility, these concrete blocks can be used in internal and external applications, performing equally as well above and below ground level. Their dense composition ensures a superior load-bearing capacity, making them ideally suited for cavity wall constructions, solid wall builds, internal structural walls, and beam-and-block flooring systems.

The standardised 100mm width provides excellent compatibility with conventional building techniques while maintaining structural integrity. With a 7.3N compressive strength rating, these blocks also guarantee reliable performance under demanding conditions, whether supporting significant loads or providing essential weatherproofing in exposed locations.
