ABSTRACT:
A method to provide a stoichiometric mixture of water, lime and cement for making an in-site piling. Water to supplement existing ground water is supplied by an augur as it drills into the ground so that a substantially uniform concentration of water exists for the full depth. Then the augur, while turning, returns to the surface while it injects and stirs into the wet soil the stoichiometric amounts of lime and cement.
