Frequently asked questions
How many pavers do I need?
Divide the area by one paver's coverage, then add 5–10% for cuts and breakage. The tool does this from your paver size.
Should I order extra pavers?
Yes — keep a few spares for future repairs, since dye lots and product lines change and an exact match later is hard to find.
