When MTBM is used to construct a tunnel in cohesive soil area, the main force need to resist is adhesive force generated by soil or clay around the machine, which can be reduced by the lubrication. In this case, the most commonly used lubrication is bentonite mud, which is injected through ports in the jacking head and filled outside of the pipes.

As described on a previous page, the pH of the water used when mixing bentonite has a significant effect on whether bentonite can be fully hydrated. The pH of the water, before adding bentonite, should be in the range of 8.5-9.5; this is slightly alkaline. There are several ways to measure pH but the easiest is to use a pH test strip.

Bentonite also has, in comparison with other fining agents, a minimal effect on the sensory properties of the treated wine (Fig. 8.10). The major drawbacks of bentonite use are color loss from red wines and a tendency to produce voluminous sediment. The latter can cause considerable wine loss during racking.

Bentonite is a clay. It does not "absorb" or "dissolve" anything. It helps to separate things in a mixture by sticking to it and then that can be filtered out. Water will "eat away" a metal spoon over time. That is called oxidizing or rusting. But clay will not do this. Bentonite is in the smectite group of clays.
