METHOD FOR STABILISATION OF SOIL OR FOUNDATION Russian patent published in 2014 - IPC E01C3/04 E01C7/36 E01C21/00 E01C23/10 E02D3/12 C09K17/40 

FIELD: construction.

SUBSTANCE: method consists in treatment of the latter by a stabiliser containing latex polymer, which is applied mixed with water. Treatment of soil or foundation is carried out by introduction of the stabiliser by means of a cutter by the cutting method as the stabiliser is mixed with ground or foundation. The latex polymer is represented by latexes from the group that includes sterol-butadiene latex, (meth)acrylate latex, ethylene-vinyl acetate latex, ethylene/propylene latex, ethylene/propylene-dimer latex, butadiene-acrylonitrile latex, silicon latex, polybutadiene latex, latex from natural rubber or mixture of two or several of the specified latexes. The stabiliser additionally comprises a thickener based on cellulose, a defoaming agent selected from the group including silicons, glycol ethers, natural fats or oils and fatty alcohols, and also at least one chloride or at least one hydroxide of alkaline or earth metal, besides, the stabiliser has the following composition (wt %); 0.1 - 50 latex polymer, 0.05 - 5 thickener, up to 5 defoaming agent, 0.01 - 10 chloride or hydroxide of alkaline or earth metal, residue to 100 - water.

EFFECT: fixation and stabilisation of soils or foundations, making it possible without removal and recycling of oil soil and special costs to perform construction-earth works.
