Things to check before you order

Dense or aircrete?

Dense blocks are strong and good for sound separation but heavy; a 100 mm dense block can weigh around 20 kg. Aircrete blocks are much lighter and insulate better, which helps with energy targets, but need the right fixings.

Thickness

100 mm is the common inner-leaf thickness. Wider blocks (140, 190, 215 mm) are used for separating walls, single-skin garage walls and foundations.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Common questions from Aberdare

What is the difference between 3.6 and 7.3 N/mm² blocks?

The number is the compressive strength. 7.3 N/mm² blocks carry more load and are often specified below ground or for heavily loaded walls; 3.6 N/mm² is common for upper storeys and partitions. Follow your drawings.

Can I use blocks in the foundations?

Yes, using blocks made for below ground, often trench blocks or dense blocks of the specified strength. Building control will check foundation design.

Do you deliver concrete blocks to trades and homeowners in Aberdare?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can you deliver concrete blocks to a site with restricted access in Aberdare?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
