Semi-Intensive
Engineered to Perform, Designed to Inspire
Achieve stormwater control, energy savings, and architectural elegance in one system.
The GreenGrid semi-intensive system strikes the perfect balance between engineering performance and visual appeal. This depth system is often selected when enhanced stormwater performance is required, and can be achieved with a slightly deeper soil profile. It is also utilized in drier climates or when additional visual interest is desired, allowing for both sedum (succulent) groundcovers and small ornamental grasses and perennials at a lighter weight than our Intensive (8”) modules. With deeper soil profiles and diverse plantings, you can transform rooftops into functional, living landscapes.
Design Elements
- Standard 2’x2’x6” modules, compatible with all other depths in mixed-depth applications Compatible with standard accessories including hardscape, edging, mineral wool stormwater storage layers, and tray inserts to create internal void space for stormwater storage.
- Accommodates a wide range of plant types: succulents, perennials, and ornamental and/or native grasses.
- Allows for custom planting layouts and landscape design.
- Compatible with dedicated irrigation systems, which are required for non-succulent plantings in all climates or dry arid or semi-arid climates.
- Non-succulent plantings may require additional horticultural care if incorporated.
- Designed for roofs with higher load-bearing capacity of at least 39-44lbs/sf.
Performance Outcomes
- Enhances building aesthetics and curb appeal.
- Improves stormwater management and reduces runoff.
- Contributes to energy conservation through active cooling during summer months and thermal mass during winter months.
- Offers a usable, nature-rich amenity space for occupants.
- Increases biodiversity and supports pollinators, particularly when including non-succulent plantings.
- Adds long-term value to the property through sustainable design.

Semi-Intensive Product Details Intermediate Depth Modules – 6 in |
|
|---|---|
| Module Size | 2 ft x 2 ft x 6 in |
| Weight | Approximately 39 to 44 lb/sf fully vegetative at maximum water holding capacity. |
| Uses | Intended for designed vegetative green roof applications or functional vegetative green roofs applications where additional soil depth, higher dry or wet weights, or greater stormwater management capacity is required. Excellent tool for managing stormwater and integrating well into new or existing buildings where there is ample structural support. |
| Plants | Succulent ground covers, conventional perennials, sedges, and grasses. When irrigated, this pallet of plant material increases. |
Semi-intensive roofs are often used as building amenities accessible to the occupants as an area to enjoy nature.
