In 2018, the company received a report that cracks had appeared in the walls of a residential house, and over time (within two years) the situation worsened – the cracks continued to open and increased in some places from 2 mm to 14 mm. As a result of a comprehensive survey, layers of foundation soil with reduced bearing capacity were identified, which led to the development of uneven settlement of the building. The cause of the reduced bearing capacity of the foundation soils could most likely be a violation of the blind area, as well as an improperly installed drainage system.
