Choosing 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.

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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Before your Flint delivery arrives

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. Flint is inside our standard mainland delivery area.

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Common questions from Flint

Is there a minimum order for delivery to Flint?

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.

How many blocks on a pallet?

It varies with the block size and maker. We confirm the pallet quantity with your price.

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

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.

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.
