A method of assisting the driving of a hollow electrically conductive pile into soil containing water by electro-osmosis in which the pile is insulated on the outside with an electrical non-conductor. An electrical circuit having a d-c power source, an anode, and a cathode is provided in which the anode is placed in the water outside of the hollow pile and the cathode is attached to the electrically conductive pile. When the pile is in contact with the soil, electrical power is applied to the circuit whereby water will be caused to move from the anode down the outside of the pile through the soil adjacent the pile and towards the cathode making the pile easier to drive through the soil. In addition, after the pile has been driven, the current is reversed through the electrical circuit for reducing the water content of the soil inside the pile and increasing the load bearing strength of the soil.
