The fracture control of the concrete, – rock, – brick structures due to the water penetration in – depth and a reliable water–proofing maintenance of the structures said above are the problems to be urgently solved in all the construction branches. At present nobody makes no doubts of the need to waterproof the structures. Among the water - proofing materials the highest working characteristics were exhibited by the water - proofing materials of a penetrating effect which reactive additives protect the concrete 5-15 cm in — depth ensuring high concrete water – proofing and low temperature resistance. This protection differs from a smearing or roll water-proofing protection by the surface fractures non – formation and temperature — independent changes during summer or winter.
