Best retaining wall installation pros near Carlock, IL

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.

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.

Yes, you can use cinder blocks for many purposes, including retaining walls, foundations, garage walls, and fences. Building a cinder block retaining wall costs between $60 and $200 per linear foot, including materials and professional labor. For a 30-foot-long retaining wall, the cost ranges from $1,800 to $6,000.

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.
