The present invention relates to a method of stabilizing sandy soils comprising the application, to the surface of the sandy soil, at one time, of 0.5 to 5 L.m−2 of an aqueous solution S comprising less than 2000 ppm of at least one water-soluble polymer A, said polymer A comprising ethylenically unsaturated monomers of which 0.01 to 20% by mol consists of at least one hydroxyalkylated monomer of formula (I) H2C═CR1R2 in which R1 being a hydrogen atom or a methyl group and R2 being a hydrocarbon group containing at least one pendant group OH and optionally at least one N or O heteroatom in the hydrocarbon chain; R2 being distinct from the C(═O)—OH, group, the other monomers being nonionic and/or anionic and/or cationic monomers different from the monomer of formula (I).
Method for stabilizing sandy soils comprising the application, to the surface of the sandy soil, in one go, from 0.5 to 5 L·m−2 of an aqueous solution S comprising less than 2000 ppm of at least one water-soluble polymer A, said polymer A comprising ethylenically unsaturated monomers of which 0.01 to 20 mol % consists of at least one hydroxyalkylated monomer of formula (I)2C═CR1R2 in which R1 is a hydrogen atom or a methyl group and R2 being a hydrocarbon group containing at least one pendant group OH and optionally at least one N or O heteroatom in the hydrocarbon chain;
