Concrete & Aircrete Blocks we supply in Hoddesdon

• Aircrete (aerated) blocksVery light, easy to cut and good insulators; check the strength grade for loadbearing work.
• Trench and foundation blocksWide blocks laid in foundation trenches instead of lots of concrete.
• Dense concrete blocksHeavy, strong blocks for loadbearing walls, below ground and good sound separation.
• Hollow and cellular blocksLighter dense blocks with voids, used for some garden and retaining walls.
• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.

Things to check before you order

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.

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.

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Concrete & Aircrete Blocks questions

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.

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.

Is there a minimum order for delivery to Hoddesdon?

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.
