Getting concrete blocks onto your Rhondda site
Blocks are banded on pallets and usually crane-offloaded where the vehicle and access allow; tell us the weight limit of any drive or the ground where pallets will sit. Rhondda is inside our standard mainland delivery area.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Getting the right concrete blocks
Handling heavy blocks
Health and safety guidance discourages laying very heavy blocks by hand for long periods. Lighter blocks or planning the lift can make a big difference on site.
What strength do I need?
Most houses use 3.6 N/mm² or 7.3 N/mm² blocks. Your structural design, your building control officer or the block manufacturer's guidance sets the grade; tell us what is specified and we will match it.
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 Rhondda
Can I add other materials to my Rhondda delivery?
Yes. Put everything on one list, from concrete blocks to fixings and PPE, and we will price it as one delivery where the products can travel together.
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.
Are aircrete blocks strong enough for an extension?
Many aircrete blocks are designed for loadbearing walls, but grades differ. Check the strength your design calls for and the manufacturer's guidance on use below DPC.
Do you deliver concrete blocks to trades and homeowners in Rhondda?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
