"Leo and team replaced our driveway, installed a patio, and built a retaining wall with an enclosed fence. They were on time, worked incredibly hard, and did a great job. He was flexible, understood our needs and overall a very nice guy. Highly recommend."

"I had C&T install a retaining wall for my driveway. When Danny promptly came out to give me an estimate I knew I wanted to hire C&T as he explained the work they put in to properly prepare the base, including required drainage, gravel, stone, etc. to have a long lasting install. They worked in extreme heat and humidity with no complaints or shortcuts, After the worked we agreed on was complete I was so happy I had them do some additional work as well. Will be contacting them again this fall for another project."

"Martin Landscaping was a pleasure to work with from day one. They did a beautiful job with our paver patio and new retaining walls. Their price was reasonable and worth every penny. Edwin and his crew were always on time and showed up as scheduled. He was extremely communicative throughout the process and addressed any and all questions. They did a wonderful job and we are so happy with how the project came out! We would 100% use this company again!"

Retaining Wall Installers questions, answered by experts

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

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.

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.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

Options include concrete, stone, brick, and wood, tailored for specific design needs.
