OWNER ASSURANCE The Garden Roof Assembly consists of proven components from the deck up, including the following; waterproofing/roofing membrane, insulation, architectural pavers (hardscape), green roof components, growing media and even the vegetation for extensive applications. Hydrotech offers a range of warranty options to an owner providing long term assurance and peace of mind from the watertightness of the membrane, up to and including the plants, as well as “removal and replacement” of the overburden. Contact Hydrotech for specifics. RESOURCES Hydrotech’s experienced sales representatives and staff work closely with your design team, and can offer assistance in the early design stage, through specification and detail development. Each project is unique, therefore each Garden Roof® Assembly is designed to meet specific objectives. Hydrotech has a variety of tools and resources that are available which may assist you in meeting your project goals. Visit our website www.hydrotechusa.com to access our specifications, details, Garden Roof Planning Guide and more. In addition, Hydrotech’s Hydrology Tool (HHT) can provide stormwater management information based on actual project conditions. Technical Benefits • Storm Water Retention • Additional Thermal Resistance • Reduced Noise Transmission Owner Incentives • Increased Life Expectancy of the Roof • Additional Usable Space • Create a Therapeutic Environment • Financial Incentives (Government) • Contribute Toward LEED® points • Image / Prestige Garden Roof® Planning Guide CONCEPT TO COMPLETION Ecological • Mitigates the Urban Heat Island Effect • Natural Habitat for Plants and Animals • Reduction of Dust and Smog Levels • Oxygen Producing / Carbon Dioxide Sink • Urban Agriculture Mashantucket Pequot Museum - Mashantucket, CT 15 HYDROTECH’S HISTORY Since 1963, Monolithic Membrane 6125® waterproofing and roofing membrane has been used in numerous parking structures and plaza applications where large areas of planting were part of the overall design. These earth covered structures were engineered to accept the heavy loads because several feet of soil and various hardscape components were incorporated into the design. These installations were not referred to as vegetated or green roofs back then, but are today by many. The difference between those early applications and the current vegetated roof market is weight. Advancements in drainage/water retention technology and lightweight engineered growing media have greatly reduced the weight of a vegetated roof, allowing it to be used on a wider range of structures. THE HYDROTECH ADVANTAGE Hydrotech’s first Garden Roof® Assembly (Mashantucket Pequot Museum) was installed in 1996; the first “single source” green roof assembly (everything from the deck up) in America. With more than 15 years of experience with all kinds of vegetated roofs, Hydrotech is in a unique position to assist you with all aspects of your project. Whether you are faced with a flat or steep slope roof, need to address stormwater retention as part of the project’s BMP/LID requirements, or need assistance in choosing the right vegetation...Hydrotech can help. Hydrotech’s flagship product Monolithic Membrane 6125 (MM6125®), a fluid applied rubberized asphalt, has been keeping buildings watertight for 50 years. Monolithic Membrane 6125®EV (environmental grade), that can be formulated with up to 25% post-consumer recycled content, is the membrane of choice for Hydrotech’s Garden Roof applications. MM6125-EV has been used in fountains, pools, reflecting ponds, planters and other applications where contact with water is to be expected. In addition to MM6125-EV’s ability to perform in a wet, submersed condition, MM6125-EV has many other unique features that make it the best choice for green roof applications… • There are no seams to fail; the membrane is completely monolithic • Bonded directly to the substrate - restricts lateral water movement if damaged • Can be installed on substrates with little or no slope • Easy to detail all critical penetrations and terminations • Resistant to fertilizers and other mild acids • No VOC restrictions; contains no PVCs • Installed ONLY by authorized, trained applicators 1996...901 Cherry - San Bruno, CA 1,750 North Park 400 - Atlanta, GA years, more than projects ... experience matters...

These earth covered structures were engineered to accept the heavy loads because several feet of soil and various hardscape components were incorporated into the design. These installations were not referred to as vegetated or green roofs back then, but are today by many. The difference between those early applications and the current vegetated roof market is weight. Advancements in drainage/water retention technology and lightweight engineered growing media have greatly reduced the weight of a vegetated roof, allowing it to be used on a wider range of structures. THE HYDROTECH ADVANTAGE Hydrotech’s first Garden Roof® Assembly (Mashantucket Pequot Museum) was installed in 1996; the first “single source” green roof assembly (everything from the deck up) in America. With more than 15 years of experience with all kinds of vegetated roofs, Hydrotech is in a unique position to assist you with all aspects of your project. Whether you are faced with a flat or steep slope roof, need to address stormwater retention as part of the project’s BMP/LID requirements, or need assistance in choosing the right vegetation...Hydrotech can help.

Once established, most extensive green roofs can rely on natural rainfall with occasional supplemental water needed if natural rainfall amounts fall short. Water accessibility and irrigation systems have been challenging issues for green roofs since their inception. Unfortunately, many green roofs have been constructed with little attention to providing enough water. The cost of plant replacement far exceeds the initial costs of a good, effective system. Hydrotech Sufficient Water Policy Hydrotech strongly recommends that sufficient water be avail- able for every Garden Roof installation. As of January 1, 2012, if sufficient water is not provided at the time of planting, Hydrotech will not ship plant material to a proj- ect unless the general contractor or owner accepts responsibility for the viability of the plant materials after installation. Irrigation System Preferences If a permanent irrigation system is being considered by the design team, Hydrotech recommends that a pop-up system be considered over a drip irrigation system for the following reasons: • Newly installed plant materials require large and consistent amounts of water during the initial establishment periods. • Drip irrigation systems cannot deliver enough lateral water to the top of the media immediately adjacent to the root zone of sedum tiles and carpets at time of installation. • As a result, drip irrigation systems can be used, but will require additional supplemental irrigation equipment and labor to provide enough overhead water for proper plant establishment. • Pop-up irrigation systems can more effectively simulate natural rainfall and apply water to the top surface of the media where the water is more available to the plants. • Pop-up irrigation systems can provide water during both establish- ment and ongoing maintenance periods. • Pop-up irrigation systems (properly designed) do not require supplemental systems to provide sufficient water. • Pop-up irrigation systems must be properly designed to keep overspray to a minimum. Sprinkler head selection and patterns are crucial to a properly designed system. Irrigation Equipment Preferences There are numerous manufacturers of temporary, drip and pop-up sprinkler equipment. For proper operation, a qualified irrigation designer/ consultant should be consulted when designing any irrigation system. Hydrotech does not recommend any particular irrigation equipment manufacturer; a list of major manufacturers is listed at the end of this document. It is the responsibility of the design team to provide an adequate irrigation and water supply system for the green roof. Minimum Water Availability If a permanent irrigation system is not included for the green roof, Hydro- tech strongly recommends that hose bibs or roof hydrants be provided at strategic locations for use in providing temporary irrigation for the green roof. These hose bib or roof hydrant water sources should be spaced no more than 100 feet apart and capable of running simultaneously with a minimum of 8-10 GPM delivered at a minimum of 35 PSI. Background Information Water during installation and establishment One of the most critical parts in the planting of any green roof is having enough water to saturate the media immediately prior to installing plant materials and for watering the plant materials after installation. Immediately prior to plant material installation, especially on hot days, water is needed in large quantities to thoroughly saturate and cool the media to prevent scorching of fine roots in all plant materials. Upon completion of the plant material installation, water must be applied in accordance to AHI maintenance requirements in order to help the roots establish deep in the media. Irrigation frequency and duration must be carefully considered. It is important to not succumb to the tempta- tion to increase irrigation frequency during hot and dry times of the year. Longer duration and less frequent irrigation cycles often work better for establishing deep roots for sedums and perennials. Shorter duration and more frequent irrigation cycles can promote shallow rooting plant materials that are more prone to stress during drier and hotter times of the year. 1/2/2019 Sufficient Water The term “Sufficient Water” is used to define the characteristics of the supplemental water needed for the initial establishment period of any vegetated roof installation. As each roof is different, the definition of “sufficient water” specific to each roof is correspondingly different and dependent on the plant material and media types and regional and climatic conditions. The requirements outlined in Hydrotech’s Maintenance Guidelines include watering the newly planted green roof on a regular basis to properly establish the plant materials. When working with owners and designers, the following are guidelines for defining characteristics for each water source: • Minimum 35 pounds per square inch (PSI) at roof level • Minimum 8-10 gallons-per-minute (GPM) at roof level Water Delivery Systems Owners and their design teams have a number of choices regarding delivering sufficient water to their green roofs: • Manual and temporary water systems via hose bibs or roof hydrants • Automatic irrigation systems such as drip and pop-up irrigation systems Water Volume and Pressure Water measurements are defined in two units: • Water volume is measured in gallons-per-minute (GPM • Water pressure is measured in pounds-per-square inch (PSI) These two units are related. It is possible to have high volumes of water with little pressure to drive the water into sprinklers or irrigation systems. Conversely, it is also possible to have high pressures with little volume which makes effective application of water time consuming and difficult to control. The ideal system has sufficient water volume and pressure to push that water effectively through the irrigation system. Water Sources The sources of water on green roofs can include hose bibs and roof hydrants that are typically used for temporary irrigation systems. For permanent drip or pop-up systems, the water source would typically lead from the mechanical roof to the roof area either through the roof deck or a wall. For vegetated roofs that will have neither drip nor pop-up irrigation systems, the following should be considered: • Number of water sources: A good standard to consider is one source every 100 feet. This will allow for using a single 50-foot hose and a temporary sprinkler to be used with minimal damage caused by dragging long hoses across new, establishing vegetation. • Water Quantity: Each water source should be capable of produc- ing at least 8-10 gallons per minute at 35-40 PSI. This will allow for proper operation of a wide range of temporary irrigation setups. Manual vs. Temporary vs. Permanent Irrigation Manual irrigation systems consist of hoses and nozzles that apply water to the media and plant material. Very labor intensive, manual irrigation requires the commitment of labor resources to be on the green roof on a very regular basis. Temporary irrigation systems typically consist of hoses and sprinklers con- nected to on-roof water sources such as hose bibs or roof hydrants. These systems are typically used during the establishment period and removed soon after. These systems require significant labor hours during the estab- lishment period to move and re-set sprinklers to ensure proper coverages over the green roof. Portable irrigation control units are available to create a semi-automatic system that helps to reduce the labor costs of turning on and off the irrigation system. 1/2/2019 Drip irrigation systems rely on capillary action between soil particles to move water laterally between the drip tubing. The porous nature of the vegetated roof medias, so essential for proper plant performance, does not create enough lateral capillary movement to deliver sufficient water to new plantings, especially sedum tiles and carpets. Once established into the media, the plant roots will seek out the water delivered by the drip irrigation system and the supplemental water can be discontinued. Given these variables, drip systems should be designed by qualified irriga- tion professionals with the following considerations: • Tubing: Drip tubing is typically embedded in the media just beneath the surface on plug projects or placed directly underneath the sedum tiles and carpets. Drip tubing can be subject to root infiltration into the drip emitters which can cause clogging. Most major tubing manufacturers have addressed this concern by incor- porating mechanical or chemical resistance to roots either in the tubing, the emitters, filters or other means and should be consid- ered in an overall irrigation system. • Tubing spacing: Typically, spacing can vary between 12 and 18 inches apart, however, the 12-inch spacing may provide better water distribution in free draining green roof medias. • Emitter Spacings: The irrigation design professional should con- sider the free-draining nature of the growing media when selecting the discharge rates and emitter spacings within the tubing. • Adequate circuitry: Green roofs should be sub-divided into logi- cal circuits or zones to minimize pressure losses and to help ensure proper operations. Multiple zones allow for isolation of various areas of the green roof for maintenance of the system without shutting down the entire system. Permanent Irrigation Systems Permanent irrigation consists of two major types: drip irrigation and pop- up spray irrigation. Drip vs. Pop-Up Irrigation Permanent irrigation systems are becoming more common on vegetated roofs with drip irrigation being the predominant system type over pop-up spray systems. Drip irrigation (sometimes referred to a sub-surface irrigation) systems consists of small diameter tubing with integral, built-in emitters that slowly release water. Drip systems employ tubing with emitters built into the tubing. The tubing and emitters can be obtained in a wide range of configurations including emitter spacings that range from 12 – 24 inches apart and emitter discharge rates that range from 0.6 – 0.9 gallons per hour. Drip systems can be designed to accommodate the highly variable geometric conditions on the vegetated roof including HVAC units as well as narrow and irregularly shaped configurations. While drip irrigation may seem to be the logical choice for vegetated roofs, the very porous and free flowing medias used for these roofs do not work well with drip irrigation systems for establishment purposes. For sedum carpet and sedum tile projects, supplemental over- head irrigation is required when establishing green roofs that have permanent drip irrigation systems. Depending on the project, plug projects may also require supplemental overhead irrigation. Clay soils Loam soils Engineered soils 1/2/2019 • Provision for supplemental water: All drip irrigation systems must have hose bibs incorporated into the systems to allow for temporary sprinkler connections that would be used during the establishment period. These hose bibs should be included at the water source and at each remote control valve in the system. Additional hose bibs should be incorporated to provide convenient connections to promote easy water application when needed. Pop-up sprinklers apply water overhead water for the vegetation. Sprinkler heads “pop-up” when in use and can vary in pop-up height from 3 to 12 inches. There are a wide variety of sprinkler units to consider with the ranges including pop-up height, spray types and patterns and wide ranges of water throw distances. It is important to consult a quali- fied irrigation professional when considering pop-up irrigation systems due to the variety of layouts and equipment options. Pop-up systems should be designed with the following considerations: • Water droplets: Sprinklers should create large water droplets rather than fine sprays or mists. This will help prevent drifting or overspray of water on rooftops that can be subject to wind effects. • 100% Overlap: Sprinklers should be spaced no further than the anticipated water throw pattern. For example, a sprinkler with a 20-foot pattern should be spaced no further than 20 feet apart. This helps to ensure even application of water over the entire surface. • Adequate circuitry: It is impractical to operate all sprinkler heads on one circuit or zone so the irrigation designer should divide the roof into logical circuits that optimize the available water and pressure. This will allow for use of sprinklers designed to address wide or narrow spaces. An advantage of pop-up irrigation vs. drip irrigation is that pop-up ir- rigation can also serve as the supplemental irrigation system during the establishment period. A properly designed, installed and maintained system can serve the dual purpose of providing water during the initial establishment period as well as during the post-establishment period. This combined function can save on labor costs during the establishment period by eliminating the need for personnel to move temporary sprinklers and hoses. Once the vegetated roof is established, the system can be adjusted to provide water as needed. Pop-up systems need to be carefully designed and installed to eliminate overthrow onto adjacent surfaces. This is especially important in areas with hard water that might stain surfaces. This may require a wider assortment of sprinkler heads to accommodate and properly cover oddly shaped areas. One disadvantage of pop-up sprinklers is the higher water pressure and volume requirements needed to properly operate these systems. These can be overcome by using booster pumps and careful water circuitry to distribute the water properly. Major Irrigation Components Booster pumps Booster pumps are often needed to raise the available water pressure and volume at the roof level. These are specialized pieces of mechanical equipment and require interconnec- tion to irrigation control- lers and other building control systems. Booster pumps should be considered as an integral part of a properly designed irrigation system. Irrigation Controllers Automatic irrigation systems are typically divided into mul- tiple circuits that address spe- cific areas of the roof. Each of these circuits are activated by remote-controlled solenoid valves that are connected to a central electronic time clock or controller. These controllers can handle many separate solenoid valves and turn them on and off using specific programs that can be customized to address certain conditions on the roof. 1/2/2019 American Hydrotech, Inc. 303 East Ohio Street, Chicago, IL 60611 800.877.6125; 312.337.4998 312.661.0731 (fax) www.hydrotechusa.com Hydrotech Membrane Corp. 10,951 Parkway, Ville D’Anjou, Quebec H1J 1S1 800.361.8924; 514.353.6000 514.354.6649 (fax) www.hydrotechmembrane.ca The information given is based on data and knowledge considered to be true and correct and is offered for the user’s consideration, investigation and verification.

There is one valve per irrigation zone and it is installed in a valve box at the beginning of the piping that supplies the water to the zone. Depending on the sys- tem, filters and other equipment can be included in valve boxes with remote control valves. Moisture Sensors In larger irrigation systems for vegetated roofs, moisture sensors can be employed to measure the levels of moisture in the growing media. This information is fed into the controller that automatically determines if the particular circuit should be activated when required. Rain Sensors Most controllers contain circuitry for adding rain sensors. A requirement in certain southern locales, rain sensors can modify the normal operations of the controller when rainfall has occurred. Backflow prevention A critical element of any irrigation system is backflow prevention. A single backflow prevention device can be used to protect an entire system and is often required by local building codes. Please consult a qualified irrigation designer for requirements in the project area.

The water needs are especially important during the installation and initial maintenance stages of the project. Water needs can vary dependent on local climate patterns, plant material types and owner expectations. The choices of whether to use manual or temporary irrigation or to invest in either drip or pop-up spray irrigation systems involve many different issues. Ultimately, the choice of system is up to the building owner. American Hydrotech is available to assist owners, designers and contrac- tors by providing perspective and input on experiences with the green roofs that it has constructed.
