Treat the patio as a layered build-up, not one single quantity
Paving jobs usually need slabs or pavers, bedding material, and jointing products rather than one single material order. This project hub helps separate those layers so the estimate matches the way patios are actually bought and built.

What changes these estimates most
Unit size, bedding depth, joint width, and the number of cuts around edges or features usually move the final order most.
Where people under-order
Patio jobs often budget for the paving units first, then discover the bedding layer and jointing products need a separate quantity check.
Before you order
