An
interior drain field works in much the same way as the channeling
system except that it runs under the floor. The installer excavates
around the basement slab's perimeter, drills weep holes at the base
of the walls, then lays perforated drainpipe in a bed of gravel.
The result is a drain field like the one outside the footing. The
pipe channels water to either a storm sewer or a sump pump.
Although
more costly than a channeling system, an interior drain field can
handle far more water, an important consideration if your basement
suffers from a high water table, a clogged exterior drain field, or
heavy seepage.
