Before you order 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.
Estimating your MOT Type 1
A 4 × 6 m area at 150 mm compacted is 3.6 m³. At about 2.1 tonnes per cubic metre plus 10% that is 8.3 tonnes, or around 10 bulk bags. Try the sub-base calculator
Planning the drop in Hatfield
Bulk bags are usually crane-offloaded where access allows; very large quantities can be priced as loose tipped loads where access allows. Hatfield is inside our standard mainland delivery area.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- On busy streets in Hatfield, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
Common questions from Hatfield
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.
Is there a minimum order for delivery to Hatfield?
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.
Does Type 1 drain?
Type 1 is reasonably free-draining when compacted, which is one reason it is used under drives and patios.
Do you deliver MOT Type 1 to trades and homeowners in Hatfield?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
