Order concrete blocks for delivery in Lowestoft

Our concrete blocks range for Lowestoft jobs

• 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.
• Block paving and edgingsOn request alongside your sub-base and sand.
• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.
• Aircrete (aerated) blocksVery light, easy to cut and good insulators; check the strength grade for loadbearing work.

Getting the right 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.

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.

Estimating your concrete blocks

A single-skin block wall in Lowestoft 7 m long and 2.1 m high is 14.7 m². At 10 blocks per square metre plus 5% you need 155 blocks, with about 0.21 tonnes of building sand and 2 bags of cement for the mortar at 1:4. Try the block calculator

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Your questions answered

Is there a minimum order for delivery to Lowestoft?

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.

How much mortar for blockwork?

Roughly 0.008 to 0.01 cubic metres of mortar per square metre of 100 mm blockwork, allowing for waste. Use our block calculator for sand and cement quantities.

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.

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

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.
