Delivering concrete blocks in Renfrew

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. Renfrew is inside our standard mainland delivery area.

• On busy streets in Renfrew, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• If neighbours share the access, it helps to let them know a lorry is coming.

Concrete & Aircrete Blocks: choosing well

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.

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.

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

Can I add other materials to my Renfrew 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.
