The calculation, without hidden assumptions
Polymeric-sand coverage changes dramatically with paver dimensions, joint width and fill depth, which is why a bag label or manufacturer coverage chart is usually the strongest purchasing input. MAXScanner supports that direct coverage method first, while also offering a transparent rectangular-grid geometry mode for planning when joint dimensions and a volumetric bag yield are known.
How to use this calculator
Choose product-coverage mode when the bag or technical sheet gives square-foot coverage for your paver and joint condition.
Use geometry mode only when you know paver length/width, joint width, fill depth and a compatible volumetric bag yield.
Apply a project allowance if appropriate and verify the final order against the manufacturer coverage chart, especially for textured pavers or irregular joints.
Where people use it
- •Paver patio and walkway joint-sand estimates
- •Comparing product coverage at different joint conditions
- •Checking whether a bag count is consistent with measured joint geometry
Example: 240 sq ft by product coverage
If the selected polymeric sand is rated to cover 60 sq ft per bag for the actual paver and joint profile, 240 sq ft requires 4 bags before any project allowance.
What the result does not assume
- •Manufacturer coverage tables should override a generic geometry estimate because real paver shape, chamfers, texture, joint profile and installation depth change actual consumption.
- •Polymeric sand is not the same material as bedding sand beneath pavers. This page models joint fill only.
Frequently asked questions
Which method should I use?+
Use product-label coverage when available because it can reflect the actual paver and joint condition better than a simple geometry model.
Why do wider or deeper joints use more sand?+
They increase the void volume between pavers, so each square foot of pavement needs more joint material.
Does this calculate bedding sand?+
No. Use the Paver Base Calculator for the bedding layer beneath the pavers.
