Water repellent soil is treated with low concentrations of a blend of alkyl polyglycoside and EO/PO block copolymer in a weight ratio range of from 6:1 to 0.5:1 of glycoside to block copolymer in order to rapidly increase the wetting rate of the water repellent soil.

Selon cette invention, un sol hydrophobe est traité avec de faibles concentrations d'un mélange de polyglycoside d'alkyle et de copolymère séquencé EO/PO dans une plage de rapport massique entre le glycoside et le copolymère séquencé comprise entre 6:1 et 0,5:1, afin d'augmenter rapidement le taux d'humidification de ce sol hydrophobe.
