The results of the study of water absorption, compressive strength and bending strength, wetting angle of ceramic and cement-sand materials, impregnated with the production of SDP “Kremniypolimer” and developed mixtures of water-soluble liquids are presented in the article. The main hydrophobic materials produced by ZDP “KremnoiPolimer” for obtaining waterproofing liquids are 136-157 M; ETS-32; AKOR-B100. On the basis of GKZH-11N and GKZH-11K experimental waterproofing fluids No. 1 K, No. 2 K, No. 1 H and No. 2 Н were developed. Ceramic wall materials and cementitious and sand samples that simulate a mortar, impregnated with experimental mixtures (No. 1 K, No. 2 K, No. 1 N, No. 2 N), as well as AQUAFIN-F, have significantly lower water absorption, substantially increases their compressive and bending strength, while the marginal angle of wetting is significantly increasing. Similar results were obtained for hydro-insulating liquids ETS-32, AKOR B-100, microemulsions 136–157 M. It should be noted that ceramic specimens after impregnation have a slightly lower water absorption, somewhat higher compressive and bending strength and a more significant increase in the wetting angle compared to cementsand samples. From materials produced by ZDP “KremnoiPolimer”, somewhat better results were shown by ETS-32 and AKOR B-100 in comparison with the microemulsion 136–157 M. On the perimeter of the building, after pouring into pre-drilled holes of waterproofing liquids, a peculiar armopoy is created due to a significant increase in the strength of the wall materials on compression and bending.
