Soil testing under foundation before PU injection
(using a Kenzelstab Penetrometer Test)
A Cone Penetrometer (Kunzelstab) is a tool for testing the density of the soil, which can penetrate as deep as 10 meters. It is used for collecting soil data under the foundation in order to assess the situation. The tool is driven into the soil by releasing a standard 30-kg weight above. Every 20 centimetres, the density (friction) of the soil is evaluated and converted into the bearing capacity that indicates the amount of load the soil can take.
