Description
Summary:The paper presents the study of defects in the hydro-insulation of the underground part of the BDT building (“The Russian State Bolshoi Drama Theater named after Tovstonogov G.A.”) after the reconstruction. Within the reconstruction of such buildings, work is often performed to deepen the floor below the existing level of the foundation to create the additional area. During excavation works for deepening, demolition of the old concrete floors and after arrangement of a new floor slab in the basement, as a result of poorly executed hydro-insulation works, capillary moisture is raised along the body of the wall. As a result, wall structures are in conditions of high humidity, which leads to their gradual destruction.
