Before your Caerphilly delivery arrives
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. Caerphilly is inside our standard mainland delivery area.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- If neighbours share the access, it helps to let them know a lorry is coming.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Before you order 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.
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.
Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
