Two full-scale destructive load tests were conducted on test piles to capture the response of post-grouted and non-post grouted piles. The results show that the relationship between end resistance and displacement developed at the pile base follows a linear model for the piles without and with post-grouting craftwork. It is observed that the limiting total skin friction of pile after post-grouting craftwork is 1.067 times that of non-post grouted pile, whereas the ultimate tip resistance of post-grouted pile is about 1.113 times that of the pile without post-grouting craftwork. At the ultimate loading level, the pile compression has been found to be 45.7% to 50.3% of the pile head settlement. For the long post-grouted pile, the pile shaft compression should be taken into account and enhancement of the shaft strength can reduce the pile head settlement.
