An exemplary composition for enhancing water repellency in cementitious material comprises a hydrophobic material solute that is dissolved in a glycol ether solvent. Thus, the composition is provided in the form of a non-aqueous solution or emulsion wherein water is in noncontinuous phase. The use of such compositions to modify cementitious compositions and the cementitious materials obtained thereby are also described.
