"I had a great experience with NGL, start to finish. To start, Holly came out, listened, measured, and started an estimate. We had some questions, selected stones from samples she dropped off, and had good communication that got us to moving forward. She returned with Manuel to double check the measurements, and the whole idea. The project started on time. The crew was here every week day for almost 3 weeks. We and our neighbors were happy with how the crew kept the site neat, and the alley accessible. The crew made a lot of sensible decisions based on their experience, and consulted us when needed. They finished off details nicely. It looks great."

"They went above and beyond for our project. They did exactly what we wanted and more. They even went as far as helping get some debris moved for us while they had their equipment out here. They built us these two beautiful rock retaining walls with ramps down the center and even went above and beyond by adding gravel to the second/third tier when I had mentioned I wanted to do it in the future. Their pricing was fair and they even helped out my mother in law to do some work. *If I could post a photo I would, but the file size is too large*"

Retaining Wall Installers questions, answered by experts

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.  

There are contractors specifically trained in the design and construction of retaining walls. Retaining wall contractors are skilled at dealing with the soil on your property and assessing what kind of drainage should be installed. They will recommend the best materials to use for the project and can handle the processing of permits by local authorities.

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.

Yes, to build a retaining wall, a permit is required. Similarly, any repairs or modifications to an existing retaining wall require permits. If the planned wall measures higher than 4 feet, most municipalities require designs and permits come through a licensed engineer. In some locations, if the wall is shorter than 4 feet, a permit may not be required. For the requirements in your area, contact your local government.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.
