Designed for flat-roof applications requiring protective walk surfacing
Said to ensure uniform spacing and elevation of paver stones
Four-squared honeycomb structure is made of high-density polyethylene and has eight vertical spacing ribs on its upper surface
Allows water to run off through to the drainage plane level and under paver stones to the drainage system
1/8-inch-thick leveling plates maintain surface alignment, compensate for minor deck and paver stone discrepancies and span slope-to-drain areas
