WHY DO retaining walls fail?

Do I need drainage behind wood retaining wall?
Most retaining walls require drainage and are built with a perforated pipe set behind the wall in a gravel base. Because the grade of this yard has a slight slope that will promote water runoff, we can skip this step on this project, but we will add gravel for drainage and back fill with dirt.
How long do block retaining walls last?
Using a concrete footing will actually prevent the wall from being able to naturally shift. How long will my retaining wall last? For a permanent wall structure, the general lifespan is generally between 50 and 100 years. This does, however, depend on the conditions of the soil and groundwater at your site.
