A roof garden is any garden on roof of a building, Humans have grown plants on top of building structures since Ancient times. There are example is in the medieval Egyptian city of Fustat, as early as the 11th century, with roof gardens built on the top of buildings. In modern Era it is often used as a way of replacing the nature destroyed due to construction of the building. Many authorities and governments have now imposed mandatory regulations to have green roofs as a part of any new development.

Green roofs have a wide range of Environmental, Social and Economic benefits. Rainsmart 30 mm Nero Drainage Cell system provides a perfect solution for successfully creating a roof garden without any traditional problems of leakages and cracking. The 30mm Drainage cell provides a uniform surface as well as an internal void for effective drainage of excessive water during heavy rainfall or irrigation cycle.

30mm Nero Cell has a unique CUP structure which provides water retention for passive irrigation and builds up a perch water table in the above soil profile for the vegetation to flourish in prolonged dry periods making a healthy roof garden. Nero Cell is made of recycled polypropylene and is inert to soil borne bacteria and chemicals.

30mm Nero Cell shallow and effective drainage profile helps landscapers make use of mature plants on roof gardens which need soil depth and water retention properties.

The green roof protects the building surface and waterproof membrane from the effects of ultraviolet light, physical damage and the extremes of temperature and weather, high temperatures in summers can cause thermal expansion in concrete and can cause water proofing to crack, 30mm Nero Cell system provides a void and creates an air gap for the heat to escape, hence reducing the risk of cracking and enhances building life.

Green roofs have significant insulation properties, significantly improved cooling in the summer and reducing heat loss in the winter, hence reducing energy consumption.

The large areas of concrete and bitumen surfaces in our modern cities soak up the solar energy and radiate it out as heat, which is commonly known as Heat Island Effect, Resulting in higher temperatures both during the day and night in the cities. Green roofs help reduce this Heat Island Effect, which improves the thermal conditions. The median daily temperature fluctuation of the bitumen ranged from 45°C, whilst the Green Roof reduced the fluctuation to 6°C. (Lui, et al 2003)

With the increase in Impermeable surfaces like concrete and bitumen in our cities, the speed at which stormwater from a downpour reaches the storm water system is too fast and creates downstream flash flooding. Green roofs system using 30mm Nero Cell & Ellipse tank module has a great ability to absorb significant amount of rainfall and store any surplus water reaching the storm water system, providing a complete point source solution.

Water passing through the permeable topsoil, 30mm Nero Drainage Cell and Geo-textile profile of the roof garden profile filters of dust and pollutants and filters stormwater enhancing its quality. at the same time green roof provides the opportunity for wildlife to re-establish themselves in a city environment.
