Abstract
Solvent-free alkyl trialkoxy-silanes whose alkyl groups have 2 to 8 carbon atoms and whose alkoxy groups have 1 or 2 carbon atoms are used for the in-depth hydrophobic impregnation of concrete. Propyl and isobutyl trialkoxy-silanes display an especially deeply penetrating hydrophobizing action which is greater than that of solutions of these silanes.
