Picking the right product

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.

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 Heston 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. Heston is inside our standard mainland delivery area.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• 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.

Your questions answered

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.

Do you deliver concrete blocks to trades and homeowners in Heston?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
