Rainwater tunnels – elements

Tunetanken rainwater tunnel – elements for rainwater management systems are designed with open ends, for an easy and fast connection and expansion of e.g. existing rainwater systems.

The rainwater tunnel – elements are connected so that the desired sizes and dimensions of the systems are achieved. The elements are finalized with e.g. an element with closed ends. The various size and connection options makes it possible meet most requests for a project-oriented system.

Tunetanken rainwater tunnels are used for environmentally friendly and sound drainage of rainwater, so that the existing sewage system is spared. At the same time, the rainwater that seeps from the tunnel and down through the ground helps to ensure the formation of groundwater. A safe and environmentally friendly system, that is fast and easy to establish.

Tunetanken rainwater tunnel – elements are made of fiber-reinforced composite material which offers many advantages compared to traditional materials.
