Subsurface drains placed within the backfill zone, in the recompacted zone of overexca- vated soil, or in relatively higher permeable material above claystone bedrock will aid in avoiding development of perched free water.
An interior drain will not intercept seepage infiltrating through the backfill zone.
Water pumped from the sump must be discharged well away from the backfill zone and the foundation.
If water is discharged near the foundation it will infiltrate into the more permeable backfill zone and be recycled in the perimeter drain.
Slopes that are parallel to the foundation simply distribute water along the foundation instead of removing it from the backfill zone.
