Abstract: The geologic exploration shows that the seepage exists between the dam bottom and foundation rock. So the seepage water on the dam foundation should be controlled. The selection of impervious scheme, the design and construction of high pressure grouting technology are introduced in this paper. The inspection result indicates that the impervious effect is fully satisfied with the need of seepage control of the dam.
