Before spending the time and energy adding drainage to an existing retaining wall, make sure the wall is worth saving. If the wall is leaning out or there are cracks in the concrete, these could be signs of irr. These openings, known as weep holes, play a crucial role. They facilitate the drainage of trapped water behind the wall, helping to avoid excessive pressure that might cause cracks or even structural failure. Without these holes, water can accumulate and gradually weaken the wall.
