Purpose. To reveal the mechanism of formation of contact zones and purposeful choice of mastic composition and its substantiation on the basis of revealing of regularities of interrelations "mastic composition – waterproofing resource". Methodology. The sequence of changes in the technical condition of roofing materials, which varies from normal without damage to emergency with intermediate satisfactory and unsuitable for normal operation depending on the specific damage and leakage of the roof affects the definition of conventional material resources, means and methods of arrangement and arrangements. roofs, as well as the mechanism and kinetics of loss of serviceability are a key factor in improving the whole set of measures aimed at making technology competitive. Results. Technologies of repair of point and local damages in the form of cracks, breaks, exfoliations which are carried out by cutting and the subsequent gluing of pieces of cloths on the prepared sites with filling, allow to receive short-term results. Elimination of continuous surface damage by applying an additional layer of rolled or mastic material is associated with the inevitable preservation in the lower layers of the causes of premature loss of operational functions of the coating. The results provide an opportunity to perform non-dismantling repair and restoration work using purposefully proposed repair composition with the minimum possible cost of resources and a high degree of mechanization. The developed technology is based on the ability of the used repair composition to impregnate and saturate the adjacent surfaces with ingredients that can eliminate damage of a certain type and return the coating or protective layer of the initial waterproofing potential and strengthen it. Originality. Substantiation of possibilities of use of the residual waterproofing resource of the existing soft roof by its saturation with ingredients of the offered repair composition. Practical value. It is possible to effectively use, restore and enhance the residual waterproofing potential of bitumen-roofing roof by pneumatic spraying repair composition of the developed composition.
