The invention relates to the use of sodium methylsiliconate or potassium methylsiliconate with a substrate in order to render it water-repellent, so that the said substrate allows good water retention when it is applied to a soil to be protected or when it is on a soil to be protected or so that the said substrate is impermeable to water. Between 180 and 1000 g of sodium methylsiliconate or potassium methylsiliconate are mixed per m3 of substrate.
La présente invention porte sur l'utilisation de méthylsiliconate de sodium ou de méthylsiliconate de potassium avec un substrat afin de le rendre hydrofuge et de faire en sorte que ledit substrat permette une bonne rétention d'eau lorsqu'il est appliqué sur un sol à protéger ou lorsque c'est sur un sol à protéger que ledit substrat est imperméable à l'eau. On mélange entre 180 et 1000 g de méthylsiliconate de sodium ou de méthylsiliconate de potassium par m3 de substrat.
