On-Grade StormwaterLeak Detection
The number one litigated construction trade in the nation is roofing and waterproofing. Now with the emergence of vegetated roofing as a more commonplace commercial application, the potential liabilities have been exacerbated through the installation of overburden on roofing/waterproofing materials. The use of water tests and thermal imaging on these covered and constantly moist conditions are no longer effective methods in determining the location of a roof leak or breach. Leak Detection is the answer to minimizing your exposure to potential building damage, reduced employee productivity and provides the peace of mind that if you have a leak that it will be resolved in a quick and efficient manner. We offer both reactive and proactive systems that will pin point any leak as close as to 2” from the source. We recommend leak detection solutions to all of our blue and vegetative roofing clients. Additionally, it is a standard requirement to receive any Hanging Gardens blue or vegetative roofing warranty. We too understand the necessity to limit our own liabilities.
Waterproofing & Insulation
Our waterproof membrane solutions provide durability, flexibility, compatibility with leak detection & prevention systems; as well ease of installation. What differentiates us from all other complete green roofing solutions is that we provide total system warranties that allow for ponding water. This enables our roofs to become stormwater capturing solutions.
Drainage & Retention
Drainage Mats and Drainage/Retention Boards are chosen based on roof slope, accessibility, compressive strength, plant palette, water retention & peak discharge delay requirements. Regardless of project need, we are able to provide an appropriate solution for your project. All of our products are recommended for flat roofs, lightweight and provide a reliable discharge of water. Specific to our drainage/retention boards, we are proud to provide the largest and most time tested line of high water retention and discharge delay drainage boards available.
Root Barrier
Our root barriers prevent root penetration into the waterproof membrane. Dependent on the roof membrane and types of plant materials chosen for a project, we provide a range of materials that can be used as a root barrier. We offer LLDPE, and HDPE Root Barriers; each product has its own specific application.
Protection Fleece
The protection fleece should fully cover the waterproof membrane and/or root barrier/slipsheets to maximize its protective qualities. Roots are meant to grow into the protection fleece, thus intertwining the vegetated roof layers to create a superior stable system. A crucial factor for the health of the vegetated roof is the rot and pathogen resistance of our protective fleeces. This will allow it to endure through constantly moist conditions.
Filter Fleece
Filter fleece for vegetated roofing is particularly engineered for the harsh conditions of roof tops and plaza decks. In these constantly moist conditions in which the depths of growing media are significantly less than conventional landscaping, it is vital to have a proven product that will stand the test of time. For almost 50 years, the products that we provide have ensured that optimum conditions will prevail for the duration of your vegetated roof.
Slope Stabilization
Slope stabilization products allow for steep slope pitch vegetated roofing. We partner with Optigruen International which is the oldest and most trusted vegetative roofing product supplier worldwide and are accepted by engineers internationally. We are able to provide solutions for steep slope vegetative roofing up to a 5:4 pitch.
Edge Restraints
Ease of install, function and customization are the three keys to an effective line of edge restraints for vegetated roofs. Regardless if your system is extensive, semi-intensive, intensive, agricultural or a retention roof, we offer the choices that will exceed your edge and separation needs for your vegetated roof.
Growth Media
We provide engineered growing media for multiple purposes in numerous markets. We do this while continually providing consistent and positive results that our clients are able to depend on. Standards such as the FLL Guidelines and continual research are directly related to our successes over the past ten years. As when we started, we are still pleased to provide a complete line of growing media products that provide shorter establishment times, reduce maintenance costs and always offer an enduring base for a healthy and thriving Rhizosphere.
Watergrip
A focus of Hanging Gardens research and development is to globally locate products and improve them for the green infrastructure for stormwater marketplace. Watergrip is no exception to that internal vision of providing new, yet proven and researched technologies to our clientele. Perfect for extensive vegetated roofs, integration into food/agricultural roofs and well as for the establishment of newly installed or transplanted plantings, watergrip provides excellent capillary action, unparalleled water, air and nutrient holding & cat ion exchange capacities. Ultralightweight for roofs and ultra-water absorbent for reduced irrigation loads.
Vegetation
Choosing the correct plant type is the first step to a successful vegetated roof. It is important to note your USDA plant zone, sun exposures of the planting area, potential wind exposures, irrigation logistics, and the pitch/slope of the roof. Time frames and maintenance burden are also key items to consider. Based on these plant characteristics, the correct plant palette can then be chosen. Hanging Gardens offers plant material for all vegetative roofing projects, regardless of their idiosyncrasies. We offer sedum cuttings, perennial plug varieties, fully vegetated sedum blankets, tiles and fully vegetated modules.
Sequestration
GreenGlass™ “Powered by Osorb®” is a family of specialized silica-based medias used to extract organic contaminants from water. It is produced in over 30 varieties to meet your site’s specific needs. Common varieties include Standard for general water treatment, BioMix for bioswales, and IronMax for brownfield remediation through in situ injection. The raw product is dry, granular, odorless, hydrophobic and non-flammable with variable grain size depending on application. It can be packaged in sealed poly open-head drums, “super sacks”, or other specialty packaging based on site needs. When contaminants in water and soils come into contact with GreenGlass™ it captures them through hydraulic conductivity. The dirtier the site, the better it is able to perform. As the product absorbs, it swells, trapping pollutants indefinitely with zero incidence of leaching. Green Glass™ “Powered by Osorb®” was engineered with the support of the National Science Foundation. Regardless of site context, it offers an innovative and enduring solution for remediating contaminated brownfields, bioswales, stormwater runoff, creating pre-treatment zones adjacent to stormwater sewers or waterways, and other specialty water treatment challenges.
Hardscaping
Our hardscaping line includes concrete, lightweight porcelain pavers & numerous varieties of eco-friendly wood tiles, as well as the pedestals systems in which they support themselves on. All products exceed the compressive strengths, ADA standards and freeze-thaw testing which will provide durability for both plaza deck and standard vegetated roofing systems as well as on-grade applications while providing superior aesthetic qualities. We are proud to offer more than 100 different styles, textures, colors and sizes to meet any of your hardscaping needs.
Porous Pavement
Porous pavers are sometimes confused with permeable pavers. Porous pavers allow for water to pass through the paver structure. Permeable paver systems only allow water to pass through the cracks between the pavers. With that said, permeable pavers are much more subject to installer error and are truly much less permeable than porous pavers due to majority of the system being impervious. Comparisons aside, our porous solutions offer much more than a high performing product. We offer a line of 50+ aesthetically appealing sizes and textures for any of your porous pavement projects.
Microporous Pavers
The Low Maintenance Microporous Paver formula provides microscopic pores within each paver that do not clog with dirt and debris and remove pollutants, unlike other porous or permeable systems. Product performance and integrity can be maintained with periodic power washes or simple street clean sweeps when needed. The pavers are installed flush to one another, which reduces the risk of cracking and chipping from vehicles and snow plows.
Rain Barrels
Rain Barrels for the commercial construction and building industry are generally overlooked for water storage and collection because they tend to be too small to be effective for commercial applications. The other issue is that there is no supplier that specializes in rain barrels for commercial sector. Hanging Gardens provides a solution for both those issues. We are the first commercial company specializing in stormwater to offer rain barrels at relevant sizes for the commercial building industry. We offer a line combining over 100+ colors, textures and sizes of rain barrels that reach up to 360 gallon holding capacities.
Stormwater Harvesting Cells
Stormwater Harvesting Cells are structural modules designed with 95% void space to maximize underground water holding capacities and/or infiltration rates. Additionally, the product offers a cost effective alternate to Large Tank Cisterns, the industry norm, with an installed cost of 50-65% of the Large Tank option. Beyond price, our 10 unique Stormwater Harvesting Cells offer a flexible solution that has the ability to take on numerous configurations of dimensions to meet any project requirement.
Large Tank Cisterns
Large Tank Cisterns are the commercial standard for onsite underground stormwater retention. Available in sizes from 600 to 50,000 gallons, Large Tank Cisterns offer the flexibility to meet any project need and tie in well with other project site plumbing designs.
Consulting
Time is money: A statistically alarming amount of green infrastructure projects relating to stormwater are either value engineered out of a project and/or are problematic after installation. This is generally due to loose specifications and poorly vetted contractors. This encompasses plaza decks, vegetated roofs, porous/permeable pavers, bioinfiltration and stormwater collection and reuse systems. Wasted time = A lower return on investment for everyone involved. The reason for this is that these projects lack a green infrastructure industry expert that will guide their team to make the best economic decisions to meet your stormwater management needs. Hanging Gardens is that expert with over 50+ years of combined experience that ensures that sustainable systems with the greatest return on your investment dollars are always effectively designed and installed on your projects. We guarantee this.
Design Integration
The use of green infrastructure; such as plaza decks, vegetated roofs, porous/permeable pavers, bioinfiltration and stormwater collection and reuse systems, for stormwater management is a component of the built environment that encompasses numerous design acumens and skilled trades. With that said, the integration of the components necessary to attain the highest value systems is a challenging proposition to ensure all that the designs remain streamlined and the installations are both effective and efficient. Hanging Gardens design integration division does not provide architectural design or engineering services. We support these services and design professionals by ensuring that the most effective components to achieve your project needs are utilized and all of the pieces are integrated properly. With over 400+ components available from Hanging Gardens repertoire of offerings, we assure that when your projects are released for bidding that you will be provided with details and specifications that will be clear, concise and result in consistent pricing that will add value to your projects.

In all actuality, it is very similar to the care needed for conventional landscaping. Hanging Gardens provides a complete array of intensive vegetated roofing systems that offer a variety of aesthetic, stormwater retention requirements and budgetary options. Please browse our intensive vegetative roofing systems to find the option that best meets your needs.
Monolithic vs Tray
Since the inception of Hanging Gardens, we have prided ourselves on education and providing choices to our clients. For the most part, Hanging Gardens does provide monolithic vegetated roofing systems, however as the most objective company in the vegetated roofing industry, we do also offer a modular or tray system as well. What we want to make clear is that like any of our products for stormwater management, we guide our clients to make the correct choice to meet their functional needs and budget. In regards to the later, more than product pricing is relative to determining what a final price for a project will be. Labor, crane, logistics, etc., are all factors when we help our clients determine what system is best for them. We take this into consideration every day when our team provides budgetary numbers to our clients; many times with multiple system offerings. We want you to make the right decision and we will direct you in the most objective manner possible for that to occur.

Traditional vs. Blue vs. Green
Previously utilized to promote evaporative cooling prior to the age of air conditioning, Blue roofing is experiencing a renaissance that once again utilizes roofs as open-air cisterns for rainwater collection. These systems offer a tremendous amount of water could that can be stored on a building’s roof, given the right waterproof membrane and structural loading capacity. Water weighs 62.4lbs per cubic foot. Most cities require that the first inch of rainfall be mitigated on site, which translates to 5.2lbs per inch of depth per square foot on a roof’s surface. Our blue roofs designs have an average depth of 2-4 inches. In addition, we ensure that every blue roof design has multiple fail-safes. This is accomplished through our leak detection systems (link to leak detection), raised scuppers which act as overflows once the roof has reached peak capacity, as well as state-of-the-art roof drains which “flush” the entire blue roof through WIFI technology. Our systems provide volume stormwater mitigation through cost effective performance products and design.
Stormwater Roofs
In dense urban areas, many times the only means to effectively contain and control stormwater is to include the roof of the building as part of the stormwater solution. Hanging Gardens is well aware of this issue and has created two vegetated roofing systems that will allow to best meet your stormwater management needs. Additionally, since we are aware of the uniqueness of rooftops, structural loading capacities as well as other environmental circumstances, we also provide custom systems utilizing our many other products. Please contact Hanging Gardens design integration department (link to design integration) to receive further details on how we may assist you with your stormwater roof.
On-Grade Stormwater
Hanging Gardens offers multiple solutions to manage onsite stormwater, i.e. bioinfiltration, porous pavements, integration of native plantings as well as stormwater collection and infiltration. We are well aware that neither of these options offer a silver bullet to consistently resolve all site specific stormwater management issues and needs. However, in combination these choices provide us with the tools that do meet the unique site specific requirements for all projects, consequently enabling us to provide our clients with the highest value choices each and every time. By imputing data sourced from your site plan and stormwater requirements into our self-developed stormwater calculator, we are able to provide you with the recommendations that will provide you with the greatest value to meet your stormwater needs. Below you will see some examples of systems that have been commonly created from these site specific analyses.
