Keller Grundbau – Historical vibro rig “Johann”

We have dressed up a special kind of treasure: Our historic vibro rig “Johann”. The “Silver Arrow” from 1959 is Keller technology of the first hour.

With 160 years of experience, Keller Grundbau is a financially strong partner for the construction industry, providing solutions to subsoil, foundation and groundwater problems with a wide range of modern technologies at its disposal.
