Choosing from our concrete blocks range

• 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.
• 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.
• Dense concrete blocksHeavy, strong blocks for loadbearing walls, below ground and good sound separation.

Delivery to County Armagh: what helps

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.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• On busy streets in County Armagh, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Getting the right concrete blocks

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.

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.

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.

Questions about concrete blocks delivery in County Armagh

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.

Is there a minimum order for delivery to County Armagh?

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.

Can I add other materials to my County Armagh 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.

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.
