The Citygreen® modular Stratacell™ system is fast becoming the favoured suspended pavement system for tree pits in urban development projects – not only in Pacific region, but also in several countries around the world.
And for several good reasons.
Stratacells are structural soil cells that come in modular units, which can then be assembled to form a skeletal matrix that supports pavement and traffic loads. This structural cell system features almost five times more available growing media compared to the traditional rock/soil method, therefore facilitating healthy root growth.
Proven by numerous laboratory tests, the Citygreen Stratacell system’s structural integrity is without equal.
As shown on the right, our Edmonton office chose to demonstrate that it can sustain the weight of an ASV PT-50 multi terrain loader.
An assembled Stratacell matrix has been FEA tested to 550kPa vertical load. The modules feature extremely high compressive strength and the unique, globally patented, interlocking feature provides correct dispersion of wheel loads throughout the matrix.
Because of its advanced engineering design, the interconnected skeletal matrix provides over 94 per cent void space for filling with soil media, or storing/detaining storm water. Due to the high structural integrity of the modules, these matrices can even be used beneath trafficked areas. Our experienced Consultants are available to discuss individual project requirements, and liaise with road Engineers.
Citygreen Systems are also advocates of environmentally friendly solutions. Aside from having a very high strength capacity, the Stratacell modules are recyclable and are manufactured from 100 per cent recycled polymer. As there are no steel components, the modules are corrosion free.
