Reconstruction of facilities often involves a change in the structural scheme of the building, in connection with this, a significant increase in external loads under existing load-bearing elements is possible. In addition, it is possible that additional load-bearing structures will appear with correspondingly new foundations. There is an urgent need to increase the bearing capacity of foundation bases. The construction of drilling-injection reinforcement piles arranged using geotechnical electric discharge technology (ERT piles) is the most acceptable for conditions of particularly cramped conditions.
