These guidelines are consistent with minimum industry guidelines established by the Concrete Masonry & Hardscapes Association. 1Joint width measured with a ruler from inside edge of paver to inside edge paver between adjacent pavers. Installer should maintain uniform joints of 1/8" for most standard product applications to ensure proper joint infill.
