Delivery to Ayrshire: what helps
Bulk bags are usually crane-offloaded where access allows; very large quantities can be priced as loose tipped loads where access allows. Our standard mainland delivery area covers Ayrshire.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
Choosing MOT Type 1
How deep?
Patios and paths commonly use around 100 mm of compacted sub-base, and domestic driveways around 150 mm or more. Soft ground or heavier vehicles need more; your designer or installer will confirm.
Compaction
Lay and compact in layers with a plate compactor. Allow extra material because it compacts down.
MOT Type 1 Sub-base questions
Do you deliver MOT Type 1 to trades and homeowners in Ayrshire?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
Can you deliver MOT Type 1 to a site with restricted access in Ayrshire?
Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
How deep should a driveway sub-base be?
Around 150 mm of compacted MOT Type 1 is common for domestic drives on firm ground; soft ground or heavier vehicles need more. Follow your installer or the paving maker's guidance.
How much MOT Type 1 do I need?
Multiply the area by the compacted depth to get cubic metres, then allow about 2.1 to 2.2 tonnes per cubic metre. At 100 mm deep, a tonne covers roughly 4.5 square metres.
