Next Level Stormwater Management

OVERVIEW

The Eco-Grass system (download brochure) is a pre-grown, instant green looses-laid system with a low maintenance grass blanket consisting of fine fescues. It is harvested like sod and rolls on top of semi-intensive engineered growing medium. Eco-Grass helps reduce water evaporation, soil erosion and weed growth. Components are easy to transport and install.

KEY FEATURES

Increase Stormwater Retention

Stormwater retention can be increased with Needled Mineral Hydro Blanket or recycled polymeric water retention layers that can hold up to 60 per cent more rainfall compared to traditional growing medium of the same thickness while remaining lighter.

Unique Design & Logo Creation

The Eco-Grass Blanket can adapt and conform to various roof designs and can be easily cut to fit any shape. The flexible blanket can drape over various depths of growing medium for an undulating roofscape. Innovative for providing an enhanced aesthetic in a custom manner, over areas that are highly visible or that do not have strict weight restriction.

CONVENTIONAL ROOFING ASSEMBLY (CRA):

The Eco-Grass vegetated system is loose-laid on a CRA which helps to protect and extend the lifespan of the roofing membrane which otherwise would be exposed to destructive elements such as ultraviolet degradation, thermal cycling, hailstone impact, and other environmental hazards.

PROTECTED MEMBRANE ROOFING ASSEMBLY (PMR):

Insulation is located above the roofing membrane. A root barrier is installed in between the insulation and roofing membrane to promote open diffusion and ensure the top surface of the insulation has a ventilating air space. The roofing ballast above the insulation becomes part of the system and acts like the drainage layer. Contact us for other roofing assemblies.

PERMIT APPROVALS AND GREEN ROOF DECLARATION

Next Level Stormwater Management provides a Survivability Report with details about the success of our projects to assist with permit processes, such as the City of Toronto permit application. For more general info or help with other municipalities, please see FAQ or contact us.

WIND UPLIFT

Independently to CAN/CSA A123.24

Next Level Stormwater Management was a key participant in developing the Canadian Standard Test Method for Wind Resistance of Modular Vegetated Roof Assembly – the first such test in the world. Contact us for more info.
