THE LEADING EDGE OF GREENROOF DRAINAGE

The Elmich VersiDrain® 60 water storage and drainage module speaks to the intersection where urban meets nature. This lightweight, interconnectable modular tray system is utilised in Extensive greenroofs – those with less than 300mm of soil – and in planter boxes with less than 300mm of soil.

The VersiDrain® 60 is comprised of a network of cells that store and drain water to ensure greater success for long-term viability of greenery. The high water storage capacity of the retention trays reduces the need for frequent irrigation and minimises fertiliser runoff, while perforations between the storage cells will inhibit the possibility of waterlogging.

Water stored in the trays is held in a network of mini-reservoirs, allowing soluble nutrients stored in the cells to be returned to the growing media, promoting healthy growth in a sustainable manner. In addition, the VersiDrain® 60 helps to mitigate stormwater runoff and regulate the discharge to storm drains during weather events. Excess water is filtered through the perforations between the water storage cells.

Manufactured from UV-stabilised recycled polypropylene, the VersiDrain® 60 supports all international Green Building certifications. The smooth and flat base of each tray means it can be placed directly over the waterproofing membrane and will safely support the growing weight of the growing media and plants. Rodent barriers integrated into the tray corners prevent rodents infesting the space between trays.

The addition of optional wall extenders – VD60 – can be added to the VersiDrain® 60 system to increase its versatility. The edge attachments extend the planting depth up to 100mm and allow contractors to pre-grow the boxes offsite if required. The VD60 attachments aid in the easy installation of the VersiDrain® 60 system onsite, achieving the instant greening of rooftops.image3
