Estimating your concrete blocks

A single-skin block wall in Gwynedd 8 m long and 2.1 m high is 16.8 m². At 10 blocks per square metre plus 5% you need 177 blocks, with about 0.24 tonnes of building sand and 3 bags of cement for the mortar at 1:4. Try the block calculator

Delivery to Gwynedd: what helps

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. Our standard mainland delivery area covers Gwynedd.

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Picking the right product

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.

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.

Concrete & Aircrete Blocks in Gwynedd: questions

Can I add other materials to my Gwynedd 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.

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

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.

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.

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.
