The article presents the results of the study of the permeability of liquids produced by ZDP “Kremniypolimer” and developed mixtures of water-soluble liquids for their use in restoring vertical and horizontal waterproofing of walls by surface impregnation, by pouring into pre-drilled holes and during waterproofing repair works due to wetting of walls. It is also possible to use these liquids for the surface treatment of walls to protect them at low capillary pressures, water or protection from the effects of rain or snow because of their hydrophobic with followed coating. The main hydrophobic materials for obtaining experimental
waterproofing fluids are solutions GKZ-11N and GKZ-11K 136-157 M; ETS-32; AKOR-B100. The silicon organic fluids GKZ-11N and GKZ-11K, as the main impregnating materials produced by SDP “Kremniypolimer”, do not withstand excess pressure of water more than 0,02 MPa when tested in a technique developed on the basis of determination of waterproofness of concrete. On the basis of GKZ-11N and GKZ-11K experimental waterproofing fluids No. 1 K, № 2 K, No. 1 N and No. 2 N were developed. All developed experimental mixtures No. 1 К, No. 2 К, No. 1 N, No. 2 N), as well as AQUAFIN-F, have sufficient permeability in ceramic wall materials and in cement-sand samples that simulate a mortar. The penetration of cement-sand samples is even slightly higher compared to ceramic samples. This, obviously, can be explained by the fact that firstly, cement-sand samples have a more developed pore system compared to ceramic samples; secondly, the roughness of porous walls is also different. The permeability of developed water-soluble mixtures No. 1 К, No. 2 К, No. 1 N, No. 2 N) is slightly higher as compared to emulsion or partially soluble in water (micro emulsion 136–157M (6 %), ЕTS-32, AKOR B -100), which, obviously, can be explained by the lower values of kinematics viscosity.
