Concrete blocks are large masonry units, normally 440 × 215 mm on face, that lay at about 10 blocks per square metre; they come as dense aggregate, lightweight aggregate or aircrete (aerated) blocks.

Planning the drop in Islington

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. Islington 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.
  • Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
  • In summer Islington gets around 16h 39m of daylight, but early deliveries still beat the traffic and give the longest working day.

Picking the right product

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.

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.

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 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 soon can concrete blocks be delivered in Islington?

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.

What is the difference between 3.6 and 7.3 N/mm² blocks?

The number is the compressive strength. 7.3 N/mm² blocks carry more load and are often specified below ground or for heavily loaded walls; 3.6 N/mm² is common for upper storeys and partitions. Follow your drawings.

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

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.
