• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.

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.

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.

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.

Delivering concrete blocks in Gerrards Cross

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. Gerrards Cross is inside our standard mainland delivery area.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
