ABSTRACT
Building materials should have such properties that buildings, in which they are used, would have desirable utility properties. The ability of building materials to fulfil required functions for certain duration of time, under action of definite factors, is called durability. The requirements for necessary durability of structure are fulfilled when all tasks: performance, strength and stability are fulfilled, during the whole life-time without substantial reduction of its utility and excessive unforeseen costs of maintenance. The significant issue is to protect properly concrete structures against the damaging effect of dampness. An essential condition for correct operating is to effectively protect the construction. The defective protection against water in an object generates destructive processes, which significantly reduce its permanence. It causes the necessity of carry out expensive repairs, in order to determine the predicted period of using the object. The protection of the concrete construction against the harmful activity of dampness is a major economical and technical problem. The general characteristic of protection against water preceded the review of selected, modern (1991÷2005) surface protections of concrete structures. Analysis of selected, modern waterproof protections brought to notice some characteristic inclinations in material solutions. The modifications of “classical” materials’ structure, both mineral and bituminous, became common. Modern waterproof protections are the composites built of – modified by various kinds of polymers – “classical” materials. These composites demonstrate very high resistance to water action, as well as for different outer influences. As a rule they demonstrate the elasticity and resistance to impacts and also very good adhesion to the concrete.
Key words: durability, maintenance, damaging effect of dampness, surface protection of concrete structures, waterproof, resistant to impacts, adhesion to the concrete.
