The paper presents the results of studying the dependence of the bearing capacity of cast-in place piles on the materials used taking into account the production technology. The type of piles considered in this work refers to cast-in-place displacement piles with an off-size big shoe (bigger than guide pipe). The concreting is done by shedding from the height as big as 35 m. In conditions of thixotropic silt clay soils and ground water pressure, the hardening of concrete takes place in aggressive media, which causes some defects of the pile shaft.
