Product details

They are available in two formats - a dense block and a medium dense block.

Dense Concrete Block

This high quality, robust and load-bearing standard concrete block is used in the majority of applications and is suitable for use above and below DPC level.

Medium Dense Concrete Block

Being midway between our Dense and Lightweight blocks, this Medium Dense block performs well for both strength and manual handling, offering a strong basis for rendering or plastering, it can also be used with dry line plasterboards.

Are These Breeze Blocks

Yes. Often referred to as breeze blocks in the UK, the CMU blocks are the most widely used building block.

Traditionally manufactured with low-cost filler materials such as ash/cinder, construction blocks are now manufactured using lightweight expanded clay aggregate (LECA) balls. In the UK breeze was historically used as a synonym for ash/cinder - so in the UK we often call them “Breeze Blocks”, whereas in the United State, they are often called “Cinder Blocks”. Their actual official name is CMU (Concrete Masonry Units) and they are specified in BS EN 771-3 to conform to UK building regulations.


These concrete blocks are suitable for:

  • Cavity wall construction
  • Solid wall constructions
  • Internal load-bearing walls
  • Beam and block flooring
  • Walls below DPC (dense blocks)


  • Compliant to BS EN 771-3
  • Sound insulation properties - acoustic separating walls to Part E of the Building Regulations
  • Water-resistant
  • Fire resistant
  • Standard CMU texture finish provides an excellent surface for mortars, renders and plasters
  • Easy to cut
  • Accepts most standard and heavy-duty fixings
  • BRE Green Guide A+ rated walls
  • Compression Strength - 7.3N & 10.4N


Bekstone products eco-friendly and sustainable - using recycled water, 100% green energy and supplied from renewable resources. These practices and processes are what allowed BREEAM to rate Bekstone as "Excellent" for its environmental metrics.
