“White Bath” Protection System of Reinforced Concrete Structures against Underground Water

New Russian regulations SP 250.1325800.2016 “Buildings and structures. Protection against groundwater” and STO NOSTROY 2.7.156–2014 “Structures of concrete and reinforced concrete. Designs of waterproof structures. Rules, control of execution and requirements for operation results” harmonized with European and establish the requirement for designing as well as the rules of execution and work control, when constructing water-proofing structures according to the protection system of A type (primary protection or “white bath”, are presented. It is shown that it is necessary to perform a complex of structural and technological measures to ensure the tightness of the structure for the period of operation in groundwater, including without additional (secondary) protection and drainage. The principles of calculation of the thermal stress state of reinforced concrete structures and their calculation for crack resistance to ensure the structural requirements of waterproof structures according to the “white bath” protection system are considered. The expediency of application of low-heat modified concretes to increase the crack resistance of enclosing structures, as well as the actual figures of increasing the consumption of reinforcement with due regard for the design requirements for crack resistance are shown. The economic feasibility of using this method of waterproofing is confirmed.
