Geocomposite drain for roof gardens and landscaping

In todays building design there is a growing interest to bring the outside in and create green spaces and a higher level of functionality to the site. Plazadeck® Drain makes this possible as it is a product that is lightweight and more efficient for horizontal drainage than granular drainage systems. Plazadeck® Drain is a geocomposite drain having cuspated HDPE core with a geotextile glued to one side to provide efficient drainage for roof top gardens, atriums, planter boxes and any other landscaped area of concrete slabs.




Featuring a crush strength of up to 200kPa, Plazadeck® Drain is easy to cut and install. Extremely durable, it resists soil chemicals and fungal growth.


Installation is simple, with the Plazadeck® Drain being unrolled (with the geotextile facing upwards) and cut to suit the required shape. Water will simple filter through the geotextile (leaving the soil behind) and is then transported (on the grade) to the edge of the area where it is collected and removed. Generally there is a waterproofing membrane or layer on the concrete surface, and the Plazadeck® Drain will not damage this layer. Plazadeck® Drain is ideal for garden areas in shopping malls, apartments, commercial and industrial complexes.
