Slope stabilization using DYWI® Drill Hollow Bars in Perth, Scotland

Stabilization of slopes in a development area with DYWI® Drill Soil Nails

The city of Perth, which is also known as the gateway to the Scottish Highlands, is a popular base for the numerous outdoor recreational activities that are available in the area. To enhance the attractiveness of Perth and encourage more people to settle there, the city council has designated new development areas for both commercial and residential building in the past few years.

The sloping ground of a large development area near Perth had to be extensively stabilized prior to commencement of a major home construction project.

To this end, DSI UK supplied a total of 800 galvanized DYWI® Drill Hollow Bars type R32N for this project. The soil nails were installed in lengths varying from 6 to 12 m by Cementation Foundation Skanska Ltd. within the scope of the construction work.
