Green roofs have become a growing roofing option with the increased desire for high-performance buildings, sustainable building products, and an attractive appearance. Green roofs slow down the water flow by retaining up to 75% of the rainwater, thus alleviating the pressure on stormwater infrastructures. When soil erodes, especially during harsh weather conditions, the slope can get damaged. For this case, the client wanted to have a high–performance rooftop for a residential property that could withstand the adverse weather conditions and give an aesthetic look.

Strata’s geotechnical experts designed an appropriate solution using StrataWeb®, which is cost-effective, technically sound and long-lasting. StrataWeb® is 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.
