tables, drawings locating all holes should accompany the tables. For a grout
curtain, a geologic section through the grout holes is the best presentation.
Holes may be represented by single lines with grout takes shown by zones in
volume of cement and/or other materials. Primary and intermediate holes
should be distinguished. Pressures, mixes, and setting times should be
shown with the holes or in notes. For blanket grouting, mine filling, or con-
tact grouting, a plan view of the grouted area showing hole locations and
other pertinent data, as listed above, is usually the best way to show the
grouting. Work sheets similar to such drawings, if kept up to date, are very
useful in evaluating the grouting effort as work progresses and serve as a
b a s e for the "as-built" drawings.
