Before the actual planning, inspection of the intended building site, that is, the subsoil comes first. Each soil type has its own properties and requirements; therefore, for all projects we investigate each layer sequence and its mechanical strength, either by means of a drill core or by dredging the soil with excavators.

Test impact pile driving

Sample ramming (impact pile driving) is the easiest and in most cases the wisest action. This action involves the ramming of project-specific profiles into the ground. By performing a controlled traction test it can be shown whether the poles are firmly inserted into the ground or not.

As a result of the investigation results, both the necessary foundation type (pile-driven foundation, rotary base, concrete foundation) as well as the pole distribution for the intended power plant can be determined.

Geological soil survey

For sample ramming we consult with a geological institution which creates with the help of on-site investigations and laboratory testing a geological survey for the building site’s subsoil. This report forms the basis of the structural analysis and allows a correct assessment of the chemical load on the hot-dip galvanized posts.
