Getting the right concrete blocks

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.

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 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.

Quantities: a worked example

A single-skin block wall in Gravesend 7 m long and 2.1 m high is 14.7 m². At 10 blocks per square metre plus 5% you need 155 blocks, with about 0.21 tonnes of building sand and 2 bags of cement for the mortar at 1:4. Try the block calculator

Getting concrete blocks onto your Gravesend 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. Gravesend is inside our standard mainland delivery area.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• In summer Gravesend gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Concrete & Aircrete Blocks in Gravesend: questions

How heavy is a concrete block?

It depends on the type and thickness. A 100 mm dense block is roughly 18 to 20 kg, a lightweight block noticeably less, and an aircrete block much less again.

Do you deliver concrete blocks to trades and homeowners in Gravesend?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can I add other materials to my Gravesend 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.
