• Trench and foundation blocksWide blocks laid in foundation trenches instead of lots of concrete.
• Aircrete (aerated) blocksVery light, easy to cut and good insulators; check the strength grade for loadbearing work.

Delivering concrete blocks in Chatham

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. Chatham is inside our standard mainland delivery area.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• With roughly 7h 51m of daylight in Chatham around the shortest day, morning deliveries leave more working light for the job.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Getting the right concrete blocks

Handling heavy blocks

Health and safety guidance discourages laying very heavy blocks by hand for long periods. Lighter blocks or planning the lift can make a big difference on site.

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.

Common questions from Chatham

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.

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.

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

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.

Can I add other materials to my Chatham 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.
