Things to check before you order

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.

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.

How much will you need?

A single-skin block wall in Dartford 4 m long and 2.7 m high is 10.8 m². At 10 blocks per square metre plus 5% you need 114 blocks, with about 0.16 tonnes of building sand and 2 bags of cement for the mortar at 1:4. Try the block calculator

Before your Dartford delivery arrives

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. Dartford is inside our standard mainland delivery area.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• On busy streets in Dartford, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
