Dak Rock Heavy

ground paving grids

Dak-Rock Heavy is a 500 mm x 500 mm x 39 mm (20" x 20" x 1⁹⁄₁₆") ground reinforcement paving solution designed to improve natural water drainage and at the same time to prevent ground erosion. It is a perfect alternative to set bricks, flagstones, openwork paving slabs and different kinds of concrete based surfaces.

An innovative interlocking system enables the connection of the panels to create a continuous surface, which become completely invisible once filled with aggregate or grass, preserving the natural character of the area.

Made of Polypropylene (PP).

It is used for the reinforcement and strengthening of grass layers destined for parking cars and/or recreational activities and/or staging.
