Pressing methods operate by jacking the piles into the ground, using the adjacent piles for reaction. This is a low noise and low vibration method, which makes it good for sensitive sites. There are two generic types of pressing rig, the ‘Japanese’ rigs, such as those by Giken and Tosa, and panel driving rigs.


existed prior to driving. For a given pile shape, the mode of disturbance depends on the type of soil. Cohesionless Soils Upon cessation of driving in cohesionless soils, the relative density is increased within the limits of 7 to 12 pile diameters around the pile shaft, and 3 to 5 pile diameters below the point.


further increases in pile capacity due to both harder driving and the use of smaller safety margins. To accommodate the harder-driving requirements, higher-strength pile materials will be necessary. Steel piles yielding strengths of 50 kips per square inch (ksi) and higher
