Overcoming the challenge with the G3 System®

The challenges. Drilling on one of the toughest soil conditions in the world; N-SPT blows ranging from 0-2 in marine clay with intermediary short lenses of sand; Usage of ground water for mixing; constant water intrusion while excavating affects slurry parameters, water table, The fine grain presented by the sands rapidly get in slurry suspension making it hard to d-sand; These challenges had never been solved with previous attempts to use polymer in Brazil successfully. The results: Production rates kept 2 pile per day in a 20m by 60 m area. Pile stabilization and pile integrity were achieved and the slurry was disposed of to the sewage system after treatment. Slurry mixing used ground water through a drainage system whilst the water table was kept 2 meters below working platform.
