Quantities: a worked example

A single-skin block wall in Northolt 10 m long and 2.1 m high is 21 m². At 10 blocks per square metre plus 5% you need 221 blocks, with about 0.3 tonnes of building sand and 3 bags of cement for the mortar at 1:4. Try the block calculator

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.

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.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Before your Northolt delivery arrives

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. Northolt is inside our standard mainland delivery area.

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Concrete & Aircrete Blocks questions

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.

Yes. We deliver across Northolt, including UB5, UB6, HA2, UB4. Northolt is inside our standard mainland delivery area. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.

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

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.

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.
