"A car accident damaged about 1/3 of fence. Damien came out and gave us a competitive price. We indicated that the fence being down was a security problem for us. He set installation asap. Great job and easy to work with. Would definitely use them again."

"The quality of the work performed was excellent. I am very pleased with the appearance of the replaced section of my driveway The front steps now look as good as new, as well. The cost exceeded the initial estimate, but I have to give them a pass on that, as there were some real surprises during removal of the old concrete (no grade preparation was done for the original driveway, just concrete poured over uneven ground, so in places it was 4" thick, and in others about 12" thick, making removal very difficult). Carlos Concrete did a good job with leveling the site and placing stone over the ground before pouring, and that should result in a better driveway long-term. My only reservation was a delay in removing the tree roots excavated from the site before pouring the new driveway section. They were professional and friendly."

Retaining Wall Installers questions, answered by experts

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.

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.

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.

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.
