The actual planning is preceded by the examination of the intended building ground. Each soil type has its own requirements; therefore, we examine the sequence of layers and the strength for each project, e.g. with the help of a drill core or by digging up the soil with excavators.
Test impact pile driving
Sample ramming (impact pile driving) is the easiest and in most cases the wisest action. Here, project-specific profiles are rammed into the ground at several points. A controlled traction test then shows whether the posts have sufficient grip in the ground.
As a result of the investigations, it is determined which type of foundation (pile-driven foundation, rotary base, concrete foundation) and which post density are necessary for the pole distribution.
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.
