Underpinning of a Pier by Microfine Cement Grouting and Compensation Grouting
G. Breitsprecher, P. S. Tóth

To enable the construction of a new lock beside a highly loaded pier, an underpinning of 3,200 m3 was made by microfine cement grouting. The characteristics of different microfine cement grouts was first examined in a trial field test. Settlements caused by the construction work were highly controlled. They were measured by a real-time monitoring system. To remediate and compensate unavoidable settlements a system for compensation grouting was necessary. The recorded values of settlement and heaving allow for an examination of the parameters of different drilling techniques and the efficiency of compensation grouting.
