Roofs with an inclination of less than 10 degrees are classified as flat roofs. Flat roofs can be put to use in many different ways: as a roof terrace, or a greened area that serves as an ecological retreat for animals and plants, or as a rainwater retention area. Greened flat roofs also improve the microclimate in towns and cities. In densely populated inner-city locations, in particular, flat roofs therefore have an important role as usable and, ideally, greened open spaces.
The various functional layers of the flat roof must be suitable for the intended use. The critical role here is played by the roof sealing – and its protection against damage. Special systems that incorporate root-barrier membranes, drainage mats, non-woven fabrics and structural protection mats have found application here. Such systems allow flat roofs, garages, carports, shopping centres, underground car parks or commercial buildings to be safely and reliably greened.
All products in the range Flat roofs
BEDRAIN Drainage Grids
BEDRAIN Drainage Grids are pressure-resistant drainage grids made of high-density polyethylene (HDPE) with non-woven fabric bonded on one or both sides, specifically for use in drainage applications under high compressive loading.
BEDRAIN Drainage Mats
BEDRAIN Drainage Mats comprise a three-dimensional random arrangement of polypropylene (PP) monofilaments. They are used for drainage, as surface drainage systems, in green roofs, for foundation wall protection, in landfill sites and in tunnel construction.
BETEX TP Non-woven Fabrics
Non-woven fabrics are the archetypal geosynthetic. Depending on the structure and composition of the fabric, they can be used as a filtering, separation and/or protective layer in highway construction, buildings, civil engineering, gardens and landscaping.
