The article is written about serious problem of the seam inundation. One way to solve this problem is to carry water shutoff . We use grouting mortar on basis of artificial resin, when do waterproof working. In our article we describe new preparation of grouting mortar. We mixed acetone-formaldehyde resin, caustic alkali and water under field conditions. The authors give five examples of various percentages of acetone-formaldehyde resin, caustic alkali and water, different curing period. Findings are written in the table. We achieve the results : increasing waterproof working efficiency, regulate time solidification grouting mortar, reduce exothermal effect, improve strength.
