Delivering MOT Type 1 in Dunbartonshire
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 Dunbartonshire.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- Give us the full postcode for the drop point; deliveries around G are priced to the exact address.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Before you order MOT Type 1
Compaction
Lay and compact in layers with a plate compactor. Allow extra material because it compacts down.
Virgin or recycled?
Recycled Type 1 can be a good option where it meets the specification; ask what your project or local authority requires.
Your questions answered
Is there a minimum order for delivery to Dunbartonshire?
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 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 Dunbartonshire?
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.
Does Type 1 drain?
Type 1 is reasonably free-draining when compacted, which is one reason it is used under drives and patios.
