A power station in Linhai, Zhejiang Province, China has undergone serious soil erosion, terrace settlement, and foundation void. It is necessary to consolidate the soil around the power station to improve the water tightness and antiseepage performance through the stable grouting technology that combines pasty grout. In this paper, we evaluated the long-term impact of seawater on the durability, such as the integrity and permeability of the grouting curtain with pasty grout, and conducted laboratory simulations on the durability of the cement curtain under seawater and its antiscour performance. We also carried out the numerical calculation of the design of grouting pressure and diffusion radius based on the geological conditions on the site.
