Getting MOT Type 1 onto your Watford site
Bulk bags are usually crane-offloaded where access allows; very large quantities can be priced as loose tipped loads where access allows. Watford is inside our standard mainland delivery area.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
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
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.
Can you tip it loose?
For larger quantities we can price a loose tipped load if the lorry can reach and there is space to tip.
Can you deliver MOT Type 1 to a site with restricted access in Watford?
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.
