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). In ad­di­tion to the ISO and CE mark, the test­ing for its prod­ucts are con­ducted in GAI-LAP ac­cred­ited labs across the U.S., U.K., and In­dia. The com­pany is a mem­ber of the In­ter­na­tional Geotech­ni­cal So­ci­ety (IGS).
