Before your Cricklewood 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. Cricklewood is inside our standard mainland delivery area.

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• With roughly 7h 49m of daylight in Cricklewood around the shortest day, morning deliveries leave more working light for the job.

Estimating your concrete blocks

A single-skin block wall in Cricklewood 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

Getting the right concrete blocks

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.

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.

Your questions answered

How soon can concrete blocks be delivered in Cricklewood?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.

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

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.

How heavy is a concrete block?

It depends on the type and thickness. A 100 mm dense block is roughly 18 to 20 kg, a lightweight block noticeably less, and an aircrete block much less again.
