Studies of the Relationship Between the Type of Hydraulic Routing, the Course of the Water Pressure Tests and Grouting Behaviour

The theme of this book is governed by the conviction that many grouting programmes do not end up being practical and thus give rise to considerable excess costs. Additionally, there may also be programmes which are either totally or for the most part unnecessary. The analysis of several grouting programmes in Chap. 3 bears out this belief. This is understandable, because the critical discussion of the previously used methods of studying and judging permeability in Chap. 4 has shown that it is impossible to make reliable judgements with them.
