Service

Throughout their working life, mine shafts are exposed to strains and stresses of many kinds. They also have to remain in service over many years - and some are more than a hundred years old. We are an experienced project partner for all renovation and repair work such as:

  • reinforcement of shaft lining
  • reinstatement of watertightness
  • deepening of shafts
  • backfilling of shafts
  • renovations for various reasons
