Floradrain® FD25

Application

Install by loose laying directly onto the root resistant membrane (overlaid with a moisture resistant mat where specified). The 2 mm diameter aeration holes must be uppermost (except when installing under hard landscapes, when the boards can be laid upside down, to allow quicker drainage). Butt joint the boards and connect with plastic clips (two per square metre). Panels can be cut with a heavy duty knife or a small toothed saw to fit around protrusions. Overlay with an appropriate filter sheet and substrate.

Description

Floradrain® FD25 is a lightweight drainage and water storage board, manufactured from thermoformed recycled polyethylene, used mostly in extensive green roof applications. The product allows aeration of the substrate; evaporation of stored water and multidirectional drainage on the underside. Hard landscaping elements can also be built directly off the board.
