"Excellent craftsmanship. Paramount Pavers more than exceeded my expectations. They were accommodating, professional, courteous, respectful and timely. I highly recommend Paramount Pavers for all aspects of landscaping and concrete work. They demolished a 55’ retaining wall, constructed a new wall and a new driveway. The work is impeccable. Great Company. Thank you Isaac, Rudy and Edwin for caring for my project, like it was your own."

"Where do I start? Paul was an absolute pro in completing our very large concrete project. He handled redoing all of the drainage and the job turned out perfectly. He is easy to work with and really knows how to deal with anything out of the ordinary that might come up. Highly recommend Paul at Concrete Pro for any residential project will also use him for some additional retaining wall work. He is my go-to contractor from here on out!"

Retaining Wall Installers FAQs, answered by experts

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.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.

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.

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.
