Combining decades of waterproofing success with the latest in green roofs, GREENSCAPES® is the custom solution for your unique green roof design. With job-specific growing media and a comprehensive range of accessories, we work with you to design and develop the perfect green roof for your specific aesthetic, functional, and structural requirements.
GREENSCAPES® green roofs are low maintenance with no irrigation required in most climates. Featuring deeper growing media for a wider variety of plants, GREENSCAPES® can even integrate pavers, benches, and water features to appear more like traditional roof gardens.
Replacing rigid, impermeable structural surfaces with plant life, green roofs are an emergent solution that provides significant benefits not only to the environment but to the people living in the green roof structure.
For easy management of the project, all key elements of a GREENSCAPES® greenroofs can be planned and obtained through CETCO. We provide a full range of components for your custom green roof solution:
WATERPROOFING MEMBRANE
Because Greenroofs generally remain moist, only a CETCO high-quality, watertight membrane should be used.
COREFLEX® 60 Waterproofing Membrane
Whether under continuous or intermittent hydrostatic pressure, COREFLEX is your most reliable barrier against water. Combining two kinds of barriers—passive and active—COREFLEX substantially reduces the possibility for leaks. With its traditional passive barrier blocking water while the active volcanic bentonite component of its core absorbs up to 15x its volume in water, it expands to seal cracks using the very pressure of the water itself to fill and block any gaps. Featuring a thermoplastic membrane with welded seams that provide a watertight barrier layer, COREFLEX is reinforced with an inserted knit polyester fabric integrally bonded to an Active Polymer Core (APC). The fabric is produced with DuPont’s Elvaloy-KEE (Keytone Ethylene Ester), a solid phase high molecular weight ethylene interpolymer that not only provides superior chemical resistance but also maintains membrane properties for long-term performance without experiencing phase separation.
STRATASEAL HR Waterproofing Membrane
A single component, 100% solid, hot-applied rubberized asphalt membrane. STRATASEAL HR is formed by applying reinforcing fabric over a base layer of rubberized asphalt and then applying a second layer of rubberized asphalt over the reinforcing fabric. Flexible and self-sealing, its exceptional adhesion limits lateral water migration to any damaged area. Eliminating the additional work as well as inaccuracy of mixing or curing with two-component products, once applied, STRATASEAL HR maintains a tenacious bond for the life of the structure.
ROOT BARRIER
GREENSCAPES GS-110 (Root Barrier, Vapor Barrier, & Protection Course): A single ply polyethylene sheet used as a root barrier with an extensive GREENSCAPES Assembly, GS-110 can also be used in deeper assemblies where no woody species are to be planted. GS-110 is manufactured with polyethylene resins that provide high tensile strength, high puncture resistance, low moisture vapor permeability, and excellent resistance to root penetration and decay.
GREENSCAPES GS-120 (Root Barrier): A reinforced thermoplastic weldable root barrier liner used within waterproofing and green roof assemblies, GS-120 features polyester woven fabric coated with a thermoplastic coating to provide high tensile strength, high puncture resistance, low moisture vapor permeability, and excellent resistance to roots and decay.
DRAINAGE
GREENSCAPES GS-300 (Drainage Composite): The GS-300 composite material promotes drainage. It consists of a non-woven polypropylene filter fabric bonded to the top side of a polypropylene drainage core made up of fused, entangled filaments that are molded into a square waffle pattern that maintains GS-300’s flexibility.
GREENSCAPES GS-310 (Stormwater Management): A stormwater retention and drainage composite product, GS-310 consists of a three-dimensional polystyrene formed dimple core that not only provides compressive strength to support subsequent layers but retains stormwater while allowing excess to drain.
MOISTURE RETENTION
GREENSCAPES GS-232 (Moisture Retention Mat): A heavyweight, non-woven geotextile composed of recycled fibers designed to retain moisture, GS-232 helps sustain Greenroof plant life while protecting against penetration (such as by garden tools) of the root barrier and waterproofing layers.
SYSTEM FILTER
GREENSCAPES GS-404 (Filter Fabric): A non-woven geotextile allowing drainage of stormwater from the growing media to the water management layer. In addition to retaining the growing media, it provides excellent laminar flow. GS- 404 maintains separation and provides a cushioning layer between the growing media from the water management layer.
GREENSCAPES GS-500 Series Growing Media: GS-500, GS-505 and GS-510 are lightweight, engineered growing media blends for green roofs. The GS-500 series consists of a uniform distribution of aggregate grain sizes and organic materials producing consistent color, structure, and texture that allows the media to maintain specified aeration, water permeability, erosion resistance, and root penetration. The GS-500 series promotes sustainability of the Greenroof with a careful balance of physical, chemical, and biological properties that promotes vegetative growth.
GREENSCAPES Plant Plug Trays (For Extensive Greenroofs): Featuring over 50 sedum varieties and more than 25 other small herbaceous perennials, GREENSCAPES plant plug trays offer a wide variety of plants suitable for growing on extensive green roofs. They are available in a standard 72-cell tray and a custom grown 24-cell tray. Specific selections can be made to suit site conditions such as light to moderate shade, high wind, hot and dry environments, or cold to moderate growing zones; selections can also be made as to suit design criteria such as maximum color, season long bloom and winter interest.
GREENSCAPES Bulk Sedum Cuttings (For Extensive Greenroofs): GREENSCAPES Bulk Sedum Cuttings are ½ - 2 ½ inch long, spontaneously-rooting stems available in a wide variety of sedums. Suitable for growing on extensive Greenroofs. Sedum cuttings are a great choice for low-cost planting of extensive Greenroofs, overplanting of plug installations, repair of damaged green roof areas, and filling in sparse areas on extensive Greenroofs.
GREENSCAPES Aluminum Edging: Separating growing media from non-vegetated zone cover such as rock ballast or pavers GREENSCAPES aluminum edging still allows free flow of water (when used with a filter fabric such as GREENSCAPES GS-404). Made of slotted, unfinished aluminum bent to form an L-shaped restraint perimeter, it’s available for both straight and curvilinear applications, in one-inch incremental vertical leg sizes ranging from 3.5 inches to 8.5 inches, with custom sizes up to 14 inches tall also available.
