Without a solid base, every paved surface sinks sooner or later. The planner calculates the crushed stone layer from your area and load class, from a light garden patio to a driveway.
How the planner calculates the base
- Pedestrian: 20 cm of 0/32 mm crushed stone, for patios and paths.
- Drivable: 30 cm, for driveways and parking spaces.
- Tank: 50 cm, a tongue-in-cheek class for absurdly overbuilt paving.
- The volume includes a 20% reserve for compaction. The weight uses about 1.7 t per m³.
How to start
- Enter the dimensions or draw the outline of your surface.

FAQ
How deep should the base be?

Can I calculate base and pavers together?
