Abstract: With the fast development of the infrastructure construction, foundation construction difficulties are encountered at different geological areas with the most difficulties in the soft soils. Among these, the ground improvement in the soft soil areas is the most important and is critical to the entire construction quality. The post grouting technique for the bored and cast-in-place concrete piles is more and more applied in the construction. This paper presents the state-of-the-art review of the post grouting mehtods.
