Foundations of ventilators KV1 and KV2 of the cleaning unit DESOx showed strong vibrations during operation of the ventilators, which restricted its operation. It was necessary to stabilize the foundations.

Stabilization was made with anchors/micropiles R32N, length 10-13 m, grouted with resins GEOPUR and GEOCREAM. In addition, subsoil directly under the foundations was grouted in order to improve its properties.

Total of 270 m of micropiles were installed.
