Point drainage
Point drainage is an effective way to direct surface water away from roads and urban spaces, protecting pavements and buildings. GH Form's point drainage is designed to be an integral part of the city's visual expression. Design and functionality come together to help you create a harmonious expression.
Dewatering for complex surfaces
GH Form's point drainage is well suited for areas with complex surface structures. The Plaza range is available in several versions for different surfaces - flat, curved, concave, for slopes and for asphalt.
Point drainage requires less excavation and levelling than line drainage, making it an economically advantageous solution, especially for complex surfaces.
Efficient water drainage in limited space
Point drainage is perfect for those areas of urban space that have limited space for water drainage, as they generally do not take up much space.
With GH Form's point drainage, you get a flexible solution that is also suitable for smaller urban spaces - without compromising on aesthetics.
Point drainage with minimal carbon footprint
Our point drainage solutions are designed for the modern urban space with a focus on the environment and sustainability. That's why the grates are made from 100 % recycled iron, ensuring that the solutions have a minimal carbon footprint. An analysis by the European Regional Development Fund shows that our water drainage solutions have a carbon footprint 75 % lower than standard water drainage solutions.
All point drainage solutions are EPD-certified, so there is full transparency on the products' carbon footprint. GH Form's point drainage solutions are therefore well suited for environmentally certified buildings.
Catch the eye with creative point drainage
At GH Form, we customise point drainage that complements the architectural solutions of urban spaces with efficient water drainage.
