• Dense concrete blocksHeavy, strong blocks for loadbearing walls, below ground and good sound separation.

Choosing 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.

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 Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Delivery to Johnstone: what helps

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. Johnstone 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.
• With roughly 6h 59m of daylight in Johnstone around the shortest day, morning deliveries leave more working light for the job.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Estimating your concrete blocks

A single-skin block wall in Johnstone 6 m long and 2.4 m high is 14.4 m². At 10 blocks per square metre plus 5% you need 152 blocks, with about 0.21 tonnes of building sand and 2 bags of cement for the mortar at 1:4. Try the block calculator

Questions about concrete blocks delivery in Johnstone

Can I add other materials to my Johnstone 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.

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.

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 Johnstone?

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.
