One of the primary drainage considerations when building a retaining wall is the proper placement and sizing of weep holes. Weep holes allow water to drain from behind the retaining wall and prevent the buildup of hydrostatic pressure, which can cause the wall to fail. The weep holes should be spaced evenly along the wall and should be large enough to handle the expected volume of water.

Another important drainage consideration is the installation of a drain pipe or channel along the base of the retaining wall. This will allow excess water to be channelled away from the wall and prevent erosion of the soil behind the wall. The drain pipe or channel should be sloped to ensure proper drainage, and it should be checked regularly to ensure that it is not blocked or clogged. In addition, it is important to consider the surrounding landscape and ensure that the drain pipe or channel is connected to an appropriate outlet to prevent flooding or erosion on adjacent properties.
