In situations where presentation is of highest importance, the Invisigrate™ pave-over grille tree grate is the answer. Designed by professionals, this invention allows the surrounding pavement to continue right up to the tree trunk. This method eliminates any trip or slip hazards pedestrians often encounter, and gives a clean style to the pavement. All the essential irrigation inlets, uplighters, and check points can still be incorporated into the pavement, with this sub-surface grille.
