Picking the right product

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.

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 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.

Sizing your order

A single-skin block wall in Holywood 9 m long and 2.4 m high is 21.6 m². At 10 blocks per square metre plus 5% you need 227 blocks, with about 0.31 tonnes of building sand and 3 bags of cement for the mortar at 1:4. Try the block calculator

How delivery works in Holywood

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.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• With roughly 7h 14m of daylight in Holywood around the shortest day, morning deliveries leave more working light for the job.

Concrete & Aircrete Blocks questions

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.

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

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

How soon can concrete blocks be delivered in Holywood?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

How many blocks per square metre?

Standard 440 × 215 mm blocks with 10 mm joints lay at about 10 blocks per square metre of wall. Add around 5 percent for cuts.
