In 2002 about 80percent of the rail infrastructure around Dresden, Germany, was destroyed by floods. At Mueglitztalbahn (Mueglitz Valley Train), near Weesenstein, the floods washed away the railway embankment and the connecting slopes.

To redesign this connection the designer suggested reinforcing the new soil embankment with geosynthetic reinforcements and a steel grid framework system as the front face.
The selected geogrid was Secugrid120/40R6. It was installed according to the design calculations, fixed to the front facing, and the fill material was compacted after covering of each layer.
Secugrid R6 uniaxial geogrids are made of polyester (PET) flat extruded monolithic bars which are welded together at their junctions.
The simple, fast and economical solution ensured that the project was finalised within several weeks and could be opened to the public shortly afterwards. m
