Strata Geosystems designs a green roof using its innovative Strataweb solution
Made by Strata Geosystems, this green roof in a residential property in Bangalore, is designed using Strataweb®, a cost-effective, technically sound and long-lasting solution
With the increased desire for high-performance buildings, sustainable building products, and aesthetics, green roofs have become a growing roofing option. A green roof is essentially a vegetated landscape on a flat or sloped roof. This option is sometimes dismissed due to the initial investment; as many do not realize its long-term cost saving and other benefits.
A green roof mitigates the effects of storm water in several ways and provides a long life-span for the roof with negligible maintenance. It slows down the water flow by retaining upto 75% of the rainwater, thus alleviating the pressure on storm-water infrastructures.
When soil erodes, especially during harsh weather conditions, the slope can get damaged. So, the client wanted a high–performance roof top for a residential property that could withstand the adverse weather conditions and also look good.
While conventional gardens on a rooftop usually consist of a few pots and planters, a green roof system can cover the whole roof area with the cultivation of plant life and without the erosion of the soil. If the whole area was landscaped, it typically would be completed with vegetated soil alone leading to heavy erosion and requiring a lot of maintenance.
Strata’s innovative approach
Strata Geosystems’ technical team of civil engineers designed Strataweb®, a confinement system made of HDPE that prevents soil from slipping off the roof. It is laid across the roof, infilled with either soil or mulch, compacted using minimal equipment, and vegetated. It supports the mulch or soil effectively to prevent erosion and therefore reduces maintenance. It is technically advanced with engineered perforations to allow for drainage. Value additions include increased life span with significantly lower maintenance, quick completion time, aesthetics, and is very environmentally friendly as it provides insulation to homes.
Strata Geosystems, a leader in the geosynthetics market across the globe, provides end-to-end solutions for soil reinforcement challenges including supply, design, and construction with its world renowned Stratagrid™ (geogrid) and Strataweb® (geocells).
