Getting concrete blocks onto your Dunoon site

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. Dunoon is in an area where deliveries are priced individually because of the distance and access, so we quote each order separately.

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• With roughly 6h 57m of daylight in Dunoon around the shortest day, morning deliveries leave more working light for the job.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Things to check before you order

What strength do I need?

Most houses use 3.6 N/mm² or 7.3 N/mm² blocks. Your structural design, your building standards surveyor or the block manufacturer's guidance sets the grade; tell us what is specified and we will match it.

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.

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

Your questions answered

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

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.

Can I add other materials to my Dunoon 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.

How many blocks per square metre?

Standard 440 × 215 mm blocks with 10 mm joints lay at about 10 blocks per square metre of wall. Add around 5 percent for cuts.

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.
