Concrete & Aircrete Blocks for Farnworth, delivered to site

Choosing from our concrete blocks range

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

How delivery works in Farnworth

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. Farnworth is inside our standard mainland delivery area.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• In summer Farnworth gets around 17h 03m of daylight, but early deliveries still beat the traffic and give the longest working day.

Choosing 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.

Your questions answered

Is there a minimum order for delivery to Farnworth?

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.

Do you deliver concrete blocks to trades and homeowners in Farnworth?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

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.

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.
