Around an approx. 50,000 m² car park for new cars of a German car manufacturer, a trench was planned to collect the surface water.

To make optimal use of the available space, the slopes of the approx. 2 m deep dreinage trench needed to be as steep as possible. Duing heavy rainfall there was a risk of erosion damage of the slopes, which was further increased by the slope steepness. Surface erosion grooves can result in unacceptable subsidence of the car park. These settlements endanger both the stability of the slope and the function of the parking area.


Erosion damade could be prevented by installing a new Naue® erosion control system. The contractor decided to use the Secumat permanent erosion control mat. A two-year combinantion product was used here consisting of a three-dimensional extruded monofilament core (Thicknedd = 20 mm) with a merchanically bonded nonwoven fabric on the bottom side.

While the applied topsoil was embedded in the extruded monofilament core in an erosion-resistant manner, the nonwoven layer provented soil prctices from washing out from underneath during heavy rainfall and initial growth. At the same time, the nonwoven fabric, archived good friction behaviour of the entire system to the subsoil, which was necessary with the 1:1.5 steep slopes and the prevailing soil.

The open extruded monofilament structure favoured rapid and long term vegetation. The Secumat® erosion control system has been in use since 2006 and protects the car park perimeter against sur-face-parallel erosion
