In modern architecture, green roofs combine energy efficiency, environmentally friendly design, and aesthetic value. For these systems to perform effectively, proper water management is essential.
TekDrain GGF 20/150 is a long-lasting drainage solution manufactured from HDPE (High-Density Polyethylene), offering high durability and environmentally friendly performance. It supports sustainable green roof applications by balancing water retention and drainage.
TekDrain GGF 20/150 is a green roof drainage board produced from HDPE, providing resistance against:
Its studded surface stores rainwater and reduces irrigation requirements by providing a water reserve for vegetation. Excess water is safely directed through the drainage channels toward the parapet according to the roof slope and removed from the system.
With a compressive strength of 150 kN/m², TekDrain GGF 20/150 can be safely used in green roof systems exposed to regular structural loads.
The green roof drainage system helps reduce heat transfer, lowering energy consumption and contributing to reduced carbon emissions.
With a 7 L/m² water retention capacity, it helps maintain moisture levels and reduces the additional irrigation requirements of plants.
Excess rainwater is guided through drainage channels toward the parapet, helping reduce the load on urban drainage infrastructure.
The drainage layer helps protect roof components from harmful UV exposure and contributes to extending the service life of the roofing system.
The HDPE material provides resistance against:
Green roof systems support healthier urban environments by helping reduce carbon dioxide levels and improving city air quality.
After installing the root-resistant membrane, İzoTeknik 5000 or 6500 series is placed. Then, TekDrain GGF 20/150 boards are installed side by side.
A GeoTeknik 1100 PP geotextile layer is placed on top. This system ensures balanced water management and allows plant roots to benefit from the stored water reservoir.
