Drainage systems of the parking space on roofs - NOPHADRAIN

For drainage of the roofs with parking space, we use products of the Dutch firm NOPHADRAIN - ND 620 and ND 620 HD.
The core of parking space on the roofs drainage system ND 620 for parking cars and parking of heavy goods vehicles and emergency vehicles is scheduled ND 620 HD. Both systems have a high compressive strength. ND 620 / ND 620 HD are excellent drainage systems that allow water run-off from the layer beneath the pavement and prevent freezing and negative phenomena in the paving in the form of their shift - scaling. This means that these two systems offer a stable substructure underneath one of the flexible pavement. These systems are subjected to testing on the long-term burden on the University of Technology, Munich, Germany.
