100mm Concrete Blocks Dense 7.3N
When you’re building structural walls, foundations or multi-storey cavity construction, the last thing you need is doubt about your materials. These 100mm Concrete Blocks Dense 7.3N are manufactured for strength, stability and consistent on-site performance — giving you confidence from first course to final inspection.
With a compressive strength of 7.3N/mm², this solid dense concrete block is designed for load-bearing and structural applications where reliability matters. Whether you’re constructing inner or outer leaves of cavity walls over three storeys, installing block and beam floor infill, or building foundation walls below DPC, these 4-inch concrete blocks deliver the structural integrity your project depends on.
Built for Structural Confidence
A 7.3N rating is not just a number on a spec sheet. It means the block is engineered to withstand compressive loads in real-world conditions, from heavy masonry above to long-term structural pressure.
On site, that translates to fewer structural concerns, smoother inspections and reduced risk of costly rework. You lay each course knowing the block is designed to perform under load, not just look the part.
The dense concrete composition provides the weight and solidity required for structural builds, while the standard 440mm x 215mm x 100mm dimensions ensure compatibility with conventional blockwork layouts. Practical. Predictable. Dependable.
Suitable for Demanding Applications
These dense blocks are widely used across residential and commercial construction where structural reliability is essential.
Cavity Walls Over 3 Storeys
Suitable for both inner and outer leaves, these 7N blocks provide the compressive strength required for multi-storey builds. When structural performance cannot be compromised, 7.3N blockwork is a proven choice.
Foundation Walls and Below DPC
Working below damp proof course level demands durable materials. The solid dense construction makes these blocks suitable for below-ground use where long-term stability is critical.
Block and Beam Floor Infill
Designed to work effectively within block and beam flooring systems, these blocks provide the infill strength required to complete structural floor assemblies safely and efficiently.
If you are looking for strong, general-purpose 100mm blockwork that meets structural requirements without overcomplicating your specification, this is the practical solution.
