Slope stabilization in Lohme, Rügen, using our soil reinforcement grids

• Year of execution: 2011
• Area: ca. 3500 m²
• Customer: Panoramahotel Lohme, Insel Rügen

In Lohme on the island of Rügen, a large-scale slope stabilization and erosion control project was carried out that combines functional stability with ecological integration. The project was prompted by a steep coastal landslide in March 2005, in which more than 100,000 m³ of soil slid down the slope. Hydrogeological investigations revealed that stagnant water had accumulated in the slope layers because large volumes of groundwater were trapped in low-permeability soil layers—this repeatedly led to a loss of stability in the lower sections of the slope.

Comprehensive slope stabilization — drainage and reinforcement

Between 2009 and 2010, a comprehensive drainage system for the toe of the slope was planned and implemented with support from the state of Mecklenburg-Western Pomerania. Horizontal slope drains, some up to 56 meters long, were used to lower the groundwater level locally by up to 4.5 meters, which significantly improved the stability of the entire slope.

The ECORASTER E50 ground grid system was then installed as a complementary measure for slope stabilization. This robust grid provides a vegetable, water-permeable ground and surface reinforcement that effectively counteracts erosion forces while supporting natural plant growth processes.

Fertilization during the growing season

Until the vegetation has become permanently rooted (for example, through hydroseeding), the ECORASTER system was additionally secured with ground anchors (at least one anchor per square meter). These ground anchors, which are up to 1 meter long, ensure that the ground grids remain firmly anchored to the slope even under short-term loads and weather conditions.

Why use ECORASTER E50 for slope stabilization?

The ECORASTER E50 is a heavy-duty ground grid with exceptional load-bearing capacity and substantial wall thickness, making it ideal for slope stabilization and erosion control applications: It reduces soil erosion caused by water flow, provides a permanently stable surface, and allows rainwater to infiltrate rather than run off the surface. In addition, once vegetated, the system integrates seamlessly into the natural landscape—a sustainable solution for sloped areas.

By combining technically sound drainage, mechanical slope stabilization, and a vegetation-friendly surface solution, this project site has been transformed into a slope that is both structurally stable in the long term and ecologically permeable to roots, supporting the natural soil and water balance while effectively limiting erosion.
