Finally, the permanent plugging of the bored hole was completed on February 6, 1996. Two applications of a polyurethane hydrophilic foam grout material were made to eliminate the ground water in-leakage. Once the in-leakage was verified stopped, the hole was filled to the level of the surrounding concrete with hydraulic cement.
