How delivery works in Harrow
Bulk bags are usually crane-offloaded where access allows; very large quantities can be priced as loose tipped loads where access allows. Harrow 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.
- With roughly 7h 49m of daylight in Harrow around the shortest day, morning deliveries leave more working light for the job.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
Before you order MOT Type 1
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.
