Before you order 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.

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.

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.

Working out quantities for your Grays job

A single-skin block wall in Grays 8 m long and 2.4 m high is 19.2 m². At 10 blocks per square metre plus 5% you need 202 blocks, with about 0.28 tonnes of building sand and 3 bags of cement for the mortar at 1:4. Try the block calculator

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Ordering concrete blocks for Grays: FAQs

How many blocks on a pallet?

It varies with the block size and maker. We confirm the pallet quantity with your price.

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.
