Weep hole in existing wall
Weep hole in existing wall
(OP)
I am involved in a project where we are backfilling against an existing below grade wall. There is a street adjacent to this wall that must be maintained. This wall has been in place for 50+ years. I have been told to add weep holes to the existing wall prior to backfilling against it. I am hesitant to agree to this. There have been no drainage issues and I am afraid that by adding these weepholes we would be changing the make-up of the soil on the street side of the existing wall. Possibly causing additional settlement/movement on the wall as the structure above is demolished. Any thoughts?

If I have the right picture, the reason for adding the weep holes would be to alevate the possiblity of hydrostatic pressure in the future behind your backfill. If you were to capture any water coming through the wall because of the weep holes by using a type of chimney drain and exiting it out into a storm water pipe somewhere or directly into the street you could solve both issues. Does that make sense?
