Before your Carmarthen delivery arrives
Bulk bags are usually lifted off by crane where access allows; tell us where they can sit and whether the ground is firm. Carmarthen is inside our standard mainland delivery area.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
Picking the right product
Gravel size
20 mm gravel suits concrete and drainage layers; 10 mm and pea gravel suit bedding pipes and paths.
Ballast or separate sand and gravel?
All-in ballast is convenient for general concrete. For more control over the mix, use separate sharp sand and gravel.
