WebbAbout half of piles were formed using bentonite slurries with the remainder under Geomud-15 polymer fluids. The polymer fluids were mixed at a concentration of 0.6 kg / m 3 which gave a Marsh funnel viscosity of 48 s. Compared to the Vasco da Gama Bridge project, the dosage of the polymer was lower but the viscosity was higher.
