Abstract
The invention relates to a process for intensifying the surface stabilization of soil susceptible to erosion by introduction of water-based adhesion-promoting impregnating compounds based on esters of polyvinyl alcohol with C1-5 monocarboxylic acids and mixtures thereof with higher monocarboxylic acids (binders) using surface-active and biologiclly compatible wetting agents. The process is characterized in that impregnation of the soil is carried out in several stages and in that an aqueous preparation containing the wetting agents is used at least in the first impregnating stage.
Binder is preferably used in a comparatively small quantity in this pre-impregnation stage.
Binder is preferably used in a comparatively small quantity in this pre-impregnation stage.
