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.

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.

How delivery works in Peterborough

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. Peterborough is inside our standard mainland delivery area.

• With roughly 7h 38m of daylight in Peterborough around the shortest day, morning deliveries leave more working light for the job.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Concrete & Aircrete Blocks questions

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.

How much mortar for blockwork?

Roughly 0.008 to 0.01 cubic metres of mortar per square metre of 100 mm blockwork, allowing for waste. Use our block calculator for sand and cement quantities.

Can I add other materials to my Peterborough 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.

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

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