Winterbourne Railway Cut near Bristol

Use of DYWIDAG Soil Nails to stabilize slopes in the UK

An interesting example of the use of DYWIDAG Soil Nails using GEWI® Threadbars was the cut for a railroad line near Winterbourne near Bristol in the UK, where unstable rock faces on both sides of the line were reinforced with galvanized GEWI® Threadbars up to 7 meters long.

For the installation of 1,200 25 mm diameter DYWIDAG Soil Nails, the railroad line had to be temporarily closed so that six drill rigs could be used in the narrow cut.
