Deep vibro techniques present flexible solutions for ground improvement. They are mainly used under foundations of structures that are to be constructed on soils of low bearing capacity. Keller developed the depth vibrator (patented in 1934), which was originally used to compact granular soils such as sand and gravel. Today Keller improves a variety of granular and cohesive soils employing a wide range of depth vibrator models and techniques.
