The ORT helical pile is easy to install and very little force is required. This means the helical piles can be turned even manually into frost-lifting and homogenous soil by 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 ORT helical pile can be easily installed into hard gravel soil even directly through asphalt. This makes e.g. the installation of traffic signs or posts very easy.
