Limitations

  • •Loose delivered topsoil settles and compacts over time — many suppliers recommend ordering 10-15% extra to account for settling.

Frequently asked questions

How much topsoil settles after delivery?

Loose topsoil can compact by roughly 10-20% as it settles and is walked on — this calculator gives the loose fill volume, so build in some margin for new lawns or beds.
