"Morton Excavation was GREAT! I asked for 2 estimates, one with a small retaining wall, one without. After receiving the estimates, I contacted Morton and asked how soon could they get started? “Next week, and we should be done in a couple days.” They did have to put me off for one day, but they completed the job in 2 days, cleaned up the work area, and did an excellent job. Thanks!!"

Retaining Wall Installers questions, answered by experts

DIY is possible for small projects. Professional installation ensures structural integrity and durability for larger walls.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

Installation typically takes 1-2 weeks, depending on the wall’s size and site conditions.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.
