Permeable Paver Calculator
Plan a permeable paver patio, walkway or driveway with paver quantity, open-graded bedding and base stone, reservoir aggregate, joint material and excavation volume in one estimate.
Start with the essentials
Start with the finished permeable-paver area. Paver size, joint coverage and the bedding, base and reservoir depths stay adjustable below after you verify the section appropriate for your site.

Method, formula & assumptions
Permeable paver material planning
Formula: PlanDIYBuild multiplies project area by each selected layer depth to estimate separate open-graded bedding, base and reservoir volumes, adds the selected extra-material allowance, estimates paver quantity from paver face area and converts aggregate volume to approximate weight using the density you enter.
Worked example: Example: a 12 × 16 ft patio has 192 ft² of surface area. The calculator keeps bedding, base and reservoir depths separate so each aggregate layer can be planned and purchased independently.
Before you buy: Permeable pavement sections are project-specific. Structural loading, soil infiltration, drainage goals, frost conditions, underdrains, aggregate gradation and local requirements can change the required layer depths and materials. Use the calculator for quantity and budget planning after verifying the section appropriate for your site.
Permeable Paver Calculator FAQ
What does the permeable paver calculator estimate?
It estimates paver quantity, open-graded bedding stone, base stone, reservoir or subbase stone, joint aggregate, approximate aggregate weight and excavation volume from the dimensions and layer depths you enter.
How deep should a permeable paver base be?
There is no universal depth. Structural loading, soil infiltration, drainage goals, climate and the selected pavement system can change the required section. Use the editable depths for material planning and verify the final design for your site.
Is a permeable paver base the same as a conventional paver base?
Not necessarily. Permeable interlocking concrete pavement commonly uses open-graded aggregate layers and aggregate-filled joints or openings so water can move through the system. Follow the selected system and local requirements.
Can I use this for a driveway?
Yes for preliminary material planning, but driveway loading makes structural verification especially important. Confirm the pavement section, subgrade preparation and drainage design before construction.
