Concrete & Aircrete Blocks for Streatham, delivered to site

What concrete blocks can we deliver to Streatham?

• Trench and foundation blocksWide blocks laid in foundation trenches instead of lots of concrete.
• Hollow and cellular blocksLighter dense blocks with voids, used for some garden and retaining walls.
• Aircrete (aerated) blocksVery light, easy to cut and good insulators; check the strength grade for loadbearing work.
• Dense concrete blocksHeavy, strong blocks for loadbearing walls, below ground and good sound separation.

Delivery to Streatham: what helps

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. Streatham is inside our standard mainland delivery area.

• On busy streets in Streatham, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• With roughly 7h 50m of daylight in Streatham around the shortest day, morning deliveries leave more working light for the job.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Things to check before you order

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.

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.

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 Streatham

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

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 soon can concrete blocks be delivered in Streatham?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.

What is the difference between 3.6 and 7.3 N/mm² blocks?

The number is the compressive strength. 7.3 N/mm² blocks carry more load and are often specified below ground or for heavily loaded walls; 3.6 N/mm² is common for upper storeys and partitions. Follow your drawings.
