Picking the right product
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.
Virgin or recycled?
Recycled Type 1 can be a good option where it meets the specification; ask what your project or local authority requires.
How delivery works in Chelsea
Bulk bags are usually crane-offloaded where access allows; very large quantities can be priced as loose tipped loads where access allows. Chelsea is inside our standard mainland delivery area.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
Quantities: a worked example
A 4 × 3 m area at 150 mm compacted is 1.8 m³. At about 2.1 tonnes per cubic metre plus 10% that is 4.2 tonnes, or around 5 bulk bags. Try the sub-base calculator
MOT Type 1 Sub-base in Chelsea: questions
Does Type 1 drain?
Type 1 is reasonably free-draining when compacted, which is one reason it is used under drives and patios.
What is the difference between Type 1 and scalpings?
Type 1 is graded to a specification so it compacts into a strong, stable layer. Scalpings are less controlled and suit less demanding areas.
Can you deliver MOT Type 1 to a site with restricted access in Chelsea?
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.
Can I add other materials to my Chelsea delivery?
Yes. Put everything on one list, from MOT Type 1 to fixings and PPE, and we will price it as one delivery where the products can travel together.
