• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.

Before you order concrete blocks

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.

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.

How much will you need?

A single-skin block wall in Croydon 6 m long and 2.7 m high is 16.2 m². At 10 blocks per square metre plus 5% you need 171 blocks, with about 0.23 tonnes of building sand and 3 bags of cement for the mortar at 1:4. Try the block calculator

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

• With roughly 7h 51m of daylight in Croydon around the shortest day, morning deliveries leave more working light for the job.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
