Situation
The developer was planning several residential buildings on the hillside north of the river Rems in Schwabisch Gmund (near Stuttgart). The pit was created with a pile wall for excavation support. This area was backfilled after the buildings were completed. In the upper slope area, which remains visible; however, the developer chose to implement a solution that allows revegation.
Geology
The slope incision is located in the Stubensandstein layer, and is therefore partly based on stiff loams.
Description
For dimensioning the nail grid pattern global stability was observed and recorded first. In a second step the near-surface instabilities were dimensioned. As is typical for most excavation activity, this slope was excavated from the top down in 1.5 m increments. Immediately following excavation the erosion control mat and TECCO® System were anchored in place with soil nails.
The solution was chosen because:
- Cohesive soils / grounds with an appropriate supply of nutrients for successful revetation,
- Active and immediate greening of the embankment by hydroseeding,
- Through future building the slope will be shaded,
- Four years ago, a similar project using TECCO® System was completed nearby and has shown successful revegetation.
