The answer to 'retaining wall drainage problems' is that poor drainage is a common issue that can lead to structural damage and safety hazards. Some common causes include inadequate drainage pipes, clogged weep holes, and improper grading that allows water to pool behind the wall. Symptoms may include standing water, leaning or bowing of the wall, and erosion at the base.
To address retaining wall drainage problems, start by inspecting the drainage system. Clean out any debris in weep holes or drainage pipes, and ensure the wall is properly graded to direct water away. You may need to install additional drainage pipes or a French drain system. For more complex issues, it's best to consult a professional landscaper or retaining wall specialist who can assess the problem and recommend the appropriate solution.
