Installation
The steel screw foundation penetrates the ground easily and very little force is required. This enables that the screw piles can be turned even manually into frost-lifting and homogenous soil using an iron bar. Over 100 foundations can be installed in a day by using a small hydraulic engine available to most construction vehicles. In this case the steel screw foundation can be easily installed into hard gravel soil even directly through asphalt. This makes the installation of traffic signs or posts very easy.
