• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.
• Block paving and edgingsOn request alongside your sub-base and sand.

Before you order concrete blocks

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

Delivery to Selkirk: 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. Selkirk is inside our standard mainland delivery area.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Your questions answered

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.

Is there a minimum order for delivery to Selkirk?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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

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

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.
