The safety and functionality of traffic installations and construction sites demand that surface water is drained away safely.
In addition, water that has infiltrated into the soil as percolating and stratum water must be collected in drainage pipes and kept away from the building structure by being diverted into a drainage ditch, channel or a drainage system.
For many years, perforated plastic pipes have been the pipes of choice and have proven their efficiency and long service life in various construction forms.
