Retaining wall weep holes needed?
I am planning to replace an existing wood retaining wall that is rotting and falling over with a Unilok block wall. It will be 3 feet tall at the highest point and 122 feet long. The area is very shady with mature maples nearby.
The soil is sandy, but damp due to the shade.
The contractors I trust all mentioned putting in a French drain behind the wall. One seemed to think that I need to add 4" pipe weep holes on the front of the wall, that he would cover with small grates.Esthetically this doesn't thrill me, and nothing I have read indicates I have to do this. Is it a good idea, or can I just run the drain off the ends of the long wall?
