Delivering concrete blocks in South Croydon

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. South Croydon is inside our standard mainland delivery area.

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• 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

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.

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.

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.

Your questions answered

How many blocks on a pallet?

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

Is there a minimum order for delivery to South Croydon?

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.

Do you deliver concrete blocks to trades and homeowners in South Croydon?

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

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.
