ABSTRACT

General specifications for grouting conforming to European practice are given in BS EN 12715:2000 and BS EN 12716:2001, Rawlings (2000).

7.1Permeation Grouting

Grouted cut-offs by permeation are considered in 5.1; the following notes amplify the requirements for improving the strength of ground. The process is versatile, but requires skill to achieve optimum results and is highly dependent on the ground investigation providing clear and usable data. The method can be costly when compared with modern jet grouting (7.6) for similar applications.
