Delivering concrete blocks in Putney

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. Putney 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.
• In summer Putney gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Choosing 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.

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.

Common questions from Putney

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.

How soon can concrete blocks be delivered in Putney?

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.

Can I use blocks in the foundations?

Yes, using blocks made for below ground, often trench blocks or dense blocks of the specified strength. Building control will check foundation design.

Is there a minimum order for delivery to Putney?

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.
