ABSTRACT

Cracks in the plaster (sometimes reaching as high as 3–4 m), discoloration of the wall, its peeling, or discoloration and peeling of wallpaper, or progressive ‘weeping’ of wall surfaces as well as deterioration of woodwork are all visible proofs of failure of the waterproofing system. Even though the structure or building may be structurally sound, damp walls make for bad sanitary-hygienic conditions for those occupying the premises. Considering the extant loads and the sensitivity of the superstructure, it was decided that the foundation should consist of RCC prismatic piles 30 cm × 30 cm in section and 10 m long. Damage to buildings and structures as a result of uneven additional settlements of their foundations as well as additional stress and fatigue phenomena in the oscillating constructions, may appear due to the development of vibrations in the soil while vibrodriving piles and sheet piles. For piling jobs inside structures under reconstruction, preference should be given to a suspension hammer.
