During grouting, insufficient spread of grout within the rock fractures is one of the major issues, which negatively impacts the resulting sealing and service live of underground structures. This study therefore took a novel effort to examine the performance of RTGC theory with aperture variations. The results provided insights of the reliability of the theory.

The reference group consisted of Lisa Hernqvist, Ali Nejad Ghafar, Robert Sturk, Almir Draganović and Patrik Vidstrand.

The study was co-financed by BeFo, SBUF, KTH and RISE.
