Abstract: The seepage prevention in the sandy gravel soils with large voids and high seepage rates is a challenge work in hydraulic projects. This paper summarizes various seepage prevention methods in sand gravel soils. Researches have been performed on the improvement of a composite grouting paste and its construction procedures. The grouting with this new composite material has been successfully applied on the seepage prevention work for the sandy gravel soils at the right embankment of Longfeng Hydraulic Power Generation Station, Jiangyou City of Sichuan Provence.
