Order concrete blocks for delivery in Belfast

Choosing from our concrete blocks range

• Lightweight aggregate blocksLighter to handle with better thermal performance than dense blocks.
• 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.

• Block paving and edgingsOn request alongside your sub-base and sand.

Getting concrete blocks onto your Belfast 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. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Concrete & Aircrete Blocks: choosing well

Thickness

100 mm is the common inner-leaf thickness. Wider blocks (140, 190, 215 mm) are used for separating walls, single-skin garage walls and foundations.

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 Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Concrete & Aircrete Blocks questions

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.

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

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 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 I add other materials to my Belfast delivery?

Yes. Put everything on one list, from concrete blocks to fixings and PPE, and we will price it as one delivery where the products can travel together.
