A tool for inserting pipe piers, the method of forming such piers and a pressure grouted pier are disclosed. The tool utilizes a complementary double clamping system which allows faster pipe insertion and minimizes loading and unloading of the foundation as the pipe is driven. The tool further allows for pressurized grout to be forced through the pipe and into a volume along at least a portion of the length of the pipe to form a pier having improved stability in unstable soil.
