Green Roof Systems

 

The GROWVista modular green roof system is the next generation of modular systems. ALWAYS EVOLVING… it’s features are based on continuous feedback & updates from code officials, stormwater regulations, designers and installers across North America.

 

The design combines total stormwater control with cost effective installation. Features include: built-in reservoirs, irrigation channels, inset handles, root-aeration vents, corner extensions for no soil-loss gaps, and sidewall gussets for added strength.

Modular Green Roof Systems

GROWVISTA 2-LITE
This ultra lightweight system incorporates a special engineered soil blend with aerated components, to meet the weight-sensitive project needs, while still fulfilling needed plant nutritional requirements.

4” Depth | 3.5” Soil | 20 psf Sat. Weight | 1.1 gal/sq H2O Ret.

 

GROWVISTA 2
The most compatible solution for a balance of weight, cost, stormwater retention, ease of installation and extensive plant natural habitat. This is the ‘go to’ system.

4” Depth | 4” Soil | 23-28 psf Sat. Weight | 1.3 gal/sq H2O Ret.

 

GROWVISTA 2X-6 & 2X-8
Deeper systems allow for more options, like greater stormwater retention, larger plant selec- tions, edibles, and a more lush aesthetic.

6”-8” Depth | 6”-8” Soil | 35-55 psf Sat. Weight | 1.9-2.6 gal/sq H2O Ret.

 

Layered Green Roof Systems

 

GRO FEATHERWEIGHT
The GRO Featherweight system is a novel solution for projects that have weight constraints or value-engineered (VE) budgets. The engineered soil composition is slightly higher in organic additives than typical extensive systems, to allow a sufficient nutrient base in a thin profile. Irrigation is highly recommended for this system, to sustain unforeseen drought conditions.

2.5” Depth | 2” Soil | 17 psf Sat. Weight | 0.6 gal/sq H2O Ret.

 

GRO 2+1
The GRO 2+1 is the perfect balance of maximum water retention within a lower-weight system. This synergy of engineered soil and premium rock wool, allows the system to work in harmony and provide the vegetation with needed nutrients and aeration, while retaining as much stormwater as a standard 4” deep system.

3.5” Depth | 2” Soil | 25 psf Sat. Weight | 1.3 gal/sq H2O Ret.

 

GRO CLASSIC
The GRO Classic is the ‘tried & true’ workhorse of the green roof industry. This standard composition has been proven for many years, and will continue to be specified. Our GRO Classic system meets the minimum stormwater retention requirements for most U.S. cities.

4.5” Depth | 4” Soil | 33 psf Sat. Weight | 1.3 gal/sq H2O Ret.

 

GRO WATERHOG & WATERHOG XL
The GRO WaterHog & WaterHog XL are high performance systems are the premium systems for stormwater management. The GRO WaterHog has the infrastructure of the Classic system, with the addition of a high-retention drainage mat, that adds almost 25% more retention than the Classic. The GRO WaterHog XL is the standard WaterHog system with an additional 1” layer of premium rock wool, which increases the retention capacity to over 50% above the Classic!

5” Depth | 4” Soil | 37 psf Sat. Weight | 1.7 gal/sq H2O Ret.
XL: 6” Depth | 4” Soil | 43 psf Sat. Weight | 2.3 gal/sq H2O Ret.
