Impact driving

Impact driving installs the piling elements dynamically. A hydraulic hammer, usually mounted on a piling rig with leader, impacts on the piling element using a ram mass. Impact driving is used for the same applications as vibrating. The hydraulic hammers currently available are able to transfer much higher dynamic forces. For this reason impact driving is commonly used for very large and long piling elements.
