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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• 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.

Concrete & Aircrete Blocks: choosing well

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.

Estimating your concrete blocks

A single-skin block wall in Hertford 4 m long and 2.4 m high is 9.6 m². At 10 blocks per square metre plus 5% you need 101 blocks, with about 0.14 tonnes of building sand and 2 bags of cement for the mortar at 1:4. Try the block calculator

Ordering concrete blocks for Hertford: FAQs

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.

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.

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

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 Hertford?
