The answer to 'my retaining wall installation looks bad' is that there are several common causes, including improper construction, poor drainage, or the use of subpar materials. Symptoms may include cracks, leaning, or uneven sections of the wall. To fix the issue, you'll need to carefully inspect the wall and address any underlying problems.
If the wall was not installed correctly, it may need to be partially or fully reconstructed by a professional landscaper. Proper drainage is also crucial, so you may need to add drainage pipes or channels to prevent water buildup behind the wall. Using high-quality, durable materials like concrete, natural stone, or interlocking blocks can also help ensure a long-lasting, attractive retaining wall.
