Concrete & Aircrete Blocks: choosing well

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.

What strength do I need?

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

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.

How delivery works in Tottenham

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. Tottenham is inside our standard mainland delivery area.

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
