Modern buildings are increasingly designed with a focus on energy efficiency, sustainability, and environmental responsibility. Within this approach, green roof systems have become one of the key elements of sustainable architecture. The efficient and long-lasting performance of these systems depends on proper water management.
TekDrain GGF 20/150 is a high-performance drainage board manufactured from durable HDPE material. Thanks to its water retention and controlled drainage features, it supports plant growth while reducing the water load on building infrastructure.
TekDrain GGF 20/150 is a green roof drainage board manufactured from HDPE (High-Density Polyethylene), offering excellent resistance against:
Its specially designed studded surface stores a certain amount of rainwater and allows excess water to drain in a controlled manner, creating an ideal moisture balance for vegetation.
TekDrain GGF 20/150 contributes to green building performance by improving thermal balance and helping reduce heating and cooling costs.
With a water storage capacity of 7 L/m², it supports plant growth, reduces irrigation requirements, and helps vegetation survive during dry periods.
Excess rainwater is directed safely toward drainage points, reducing the load on urban infrastructure systems.
The HDPE structure provides long-term resistance against:
Provides additional protection against the harmful effects of sunlight exposure on roof systems.
Supports sustainable construction by:
After placing the root-resistant membrane, İzoTeknik 5000 or 6500 series is installed. The drainage boards are then placed side by side without overlapping.
A GeoTeknik 1100 PP geotextile layer is applied on top to ensure access to the water reservoir and maintain proper drainage balance.
