"I give my highest recommendation to Concrete Solutions. They did exactly what they said they would do and at a reasonable price. They worked neatly and efficiently. The crew was very respectful of my property and abided by Covid-19 safety protocals. If you need basement water-proofing, this company can do the job."

"Dan and his team of Clinton and Julie worked very hard installing a stone step to exit a room on the South side of my house. Julie also pruned a large and unwieldy Rhododendron in my front yard. Dan kept me informed as to when they would arrive and they were very polite and considerate. I am happy with the results. The new step is a wedge-shaped stone that will drain rain water and it provides a comfortable distance for stepping to the outside of the house."

"Dan did a beautiful job trimming my very large hedge and an arborvitae shrub. He was an excellent communicator, easy to schedule, had the correct equipment for the job, worked efficiently, and charged a fair price. This was a small job and he was quite willing to take it. I look forward to having him back for landscaping, lawn, and garden related jobs as needed."

Retaining Wall Installers FAQs, answered by experts

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

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, a railroad tie retaining wall consisting of a single line of ties should be between 3 and 4 feet tall—and the height often tops out at around 6 feet. You can go taller, but you may need additional footings and reinforcements, including a second layer of railroad ties to support the added weight of the soil it’s holding back.

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.

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.
