Before you order
Start with the specification.
Bring your drawing or materials list so we can help you find the right products.
Ask the teamChoose the block type
Lightweight, dense and foundation blocks suit different specifications. Follow the requirements set for the build.
Check dimensions and strength
Confirm the size and stated compressive strength in the product information. For structural work, use the specification from the project designer.
Work through quantities
Share the wall dimensions, openings and block size. Remember to plan mortar and the other materials on your list.
Good to know
A few useful answers.
A little practical detail before you choose your materials.
Do all concrete blocks do the same job?
No. Block density, size and strength vary. Choose from the product specification required for your project, rather than appearance alone.
Can I use these for a retaining wall?
Retaining walls need a suitable design for the ground and retained height. Confirm the construction and material specification with your designer or installer before choosing blocks.
Can you arrange delivery?
Send us the quantity, postcode and access details. We’ll confirm availability and delivery arrangements for your address.
