Before you order concrete blocks
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.
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.
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.
How delivery works in Newtown
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. Newtown is inside our standard mainland delivery area.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
