drenotube® DR370L6 is a pre-assembled drainage system to:
• Minimise the environmental impact of road runoff on the receiving water surrounding environment.
• Ensure the fast removal of surface water to enhance safety and minimise disruption to road users.
• Maximise the longevity of the road surface and associated infrastructures.
Water has a damaging effect on road pavements and therefore needs to be evacuated through surface, transverse and underground drainage systems. The adverse effects are numerous; entrainment and fines expulsion, accelerated structural failure in pavements and shortening their useful life. The major drainage element in a pavement is its sub-base layer while the major drainage medium for ground water consists of both longitudinal and transverse drainage ditches.
