New developments in rock and soil grouting:design and evaluation

There are two major components in a soil grouting operation. The first step is the design of a site-specific grouting programme. The second step is the execution of that programme - this includes on-site monitoring and assessment of the operation in real-time. If these tasks are undertaken with state-of-the-art engineering methods, then the best achievable results will be predictably accomplished. Two recent developments are discussed in this paper, first, an in situ soil injection simulator (ISIS) developed for use during the design phase of a soil grouting programme; secondly, a computer aided grouting evaluation system (CAGES) developed for use during the execution phase of a soil or rock grouting programme.
