VersiDrain® consist of lightweight, interlocking modular trays used for extensive green roof systems on new or existing flat and low sloped roofs. A variety of designs enables it to be used on flat, curved or irregular shaped roofs. The water stored within the reservoirs reduces irrigation requirements for sustainable plant growth.
Research worldwide has shown that green roofs limit the impact of climate change, underlining the valuable role they play in sustainable design. They reduce heat transmission from rooftop to habitable space below, lower ambient temperature, mitigate urban heat island effect, reduce rainwater runoff, and improve air quality and aesthetics.
The VersiDrain® series of interlocking, modular trays are manufactured from recycled polypropylene and are designed for the deployment of shallow media, low maintenance, ‘Extensive’ green roofs. The trays are designed to be lightweight with built-in water retention reservoirs and smooth flat bases for placement directly on roof waterproof membranes.
- VersiDrain® consists of lightweight modular green roof trays designed for versatility and are either flexible or rigid depending on the specific model.
- VersiDrain® trays comprise of a network of reservoirs that stores rainwater for the self- irrigation of plants, thus reducing watering requirements and costs as well as promoting plant growth in a sustainable manner.
- VersiDrain® trays has a smooth and flat base which allows it to be placed directly on roof waterproofing membranes thus protecting it and eliminating the need for a screed covering.
- VersiDrain® trays are manufactured from UV-stabilised recycled polypropylene, are recyclable and supports all international Green Building certifications.
- VersiDrain® trays help mitigate the impact of urban stormwater runoff by reducing the discharge to storm drains during periods of heavy downpour.
- Design Flexibility – The lightweight trays may be interlocked at right angles which enables versatile, rapid installation, minimising on-site disruption during the deployment of green roofs.
- Water Retention – Extensive VersiDrain® Green Roofs enables the retention of up to 32l/m² of precipitation or excess irrigation on site thus conserving water for sustainable self-irrigation.
- Water Detention – Extensive VersiDrain® Green Roofs enables the detention of precipitation on site thus reducing run-off to urban storm water systems.
- Efficient Water Drainage – VersiDrain® trays are designed with water drainage channels for efficient water drainaged
- Reduced Maintenance – roofing materials and waterproofing membranes are protected against UV degradation, hail and storm conditions.
- Reduced Energy Costs – radiation is minimised through growth media insulation which ensures cooler buildings in the summer and warmer buildings in winter.
- Better Sound Protection – inter level noise transfer is minimized.
- Improved Environment – plant species minimize greenhouse gas emissions, pollutants are adsorbed onto growth media particles and plant species provide a habitat for a diverse range of fauna.
- Improved Property Value – Planted roof areas increase the ‘permeable to hard-stand’ ratio on building sites and allow the creation of utilizable commercial and recreational roof gardens and terrace areas.
- Able to flex and bend as well as nest – Ability to flex allows VersiCell® 3150 to be used against curved surfaces. On-site storage and container space requirements and transportation costs is reduced by ability to nest and stack.
- Sustainable and Environmentally Friendly – VersiDrain® is made from recycled plastics and support Green Label Certification.
- No specialised installation equipment required.
- Support US LEED™ credits
