Delivering MOT Type 1 in Northamptonshire
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 Northamptonshire.
- Give us the full postcode for the drop point; deliveries around NN are priced to the exact address.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- If neighbours share the access, it helps to let them know a lorry is coming.
MOT Type 1 Sub-base: choosing well
Virgin or recycled?
Recycled Type 1 can be a good option where it meets the specification; ask what your project or local authority requires.
Compaction
Lay and compact in layers with a plate compactor. Allow extra material because it compacts down.
MOT Type 1 Sub-base questions
Does Type 1 drain?
Type 1 is reasonably free-draining when compacted, which is one reason it is used under drives and patios.
Is there a minimum order for delivery to Northamptonshire?
There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
Can you deliver MOT Type 1 to a site with restricted access in Northamptonshire?
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 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.
