WATERPROOFING INJECTION COMPOSITION FOR THE BUILDING OBJECTS UNDERGROUND PROTECTION (OPTIONS) Russian patent published in 2018 - IPC E02D31/02 

FIELD: construction.

SUBSTANCE: group of inventions relates to the repair and insulation compositions and can be used to eliminate leaks in the buildings and structures underground parts, in hydraulic engineering construction and the mining enterprises operation. Waterproofing injection composition contains, according to the first variant, 10–99 wt % of bentonite clay, containing montmorillonite minerals, 0.1–90 wt % siliceous rock in the form of fine silica, 0.1–50 wt % sodium polyacrylate, 0.1–30 wt % anionic polyacrylamide, 0.7–70 wt % fatty acids triglycerides with the free fatty acids and waxes admixtures. According to the second variant, the composition contains 10–99 wt % of bentonite clay, containing montmorillonite minerals, 0.1–90 wt % siliceous rock in the form of fine silica, 0.1–50 wt % AK series acrylic water-absorbing polymer, 0.1–30 wt % anionic polyacrylamide, 0.7–70 wt % polyatomic alcohols.

EFFECT: technical result is increase in the waterproofing quality and reliability, enabling the waterproofing operations environmental compatibility and expansion of the composition operational use.
