We look forward to building lasting relationships, and guarantee your satisfaction. Give us a call today to get your project started!

"It has been three years and we are still fixing the mistakes made by North Atlantic. Not only did they not listen when we were originally installing the patio, graded the patio into our garage (fun when it rains), they have ruined a large portion of our yard and our garden by extending the sand, rocks, and landscape fabric over 5 feet past the patio we asked them to install. When we asked them to fix it 3 years ago, they came and promised that it was all set. We have lost hundreds of dollars in plants and grass due to their lack of quality or promise. This was my 3rd effort to remove their mess and has cost me not only money, but 15+ hours of personal hard labor to repair the damage. I would not recommend them to anyone and I wasnâ t going to post anything, but spending 6 hours digging everything up yesterday, made me feel otherwise. Stay away!"

Retaining Wall Installers questions, answered by experts

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.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

DIY is possible for small projects. Professional installation ensures structural integrity and durability for larger walls.

The lifespan of a retaining wall varies based on its particular material, whether it was properly installed, how well it’s maintained, and your local climate. Concrete, stone, and brick retaining walls last the longest, with concrete lasting between 50 and 100 years on average. Brick tends to last the longest, with a minimum of one century, under the right conditions. 

Timber retaining walls can start to deteriorate at 20 years, depending on the wood quality, but in the best case, they can last 40 years. Pressure-treated wood retaining walls last 30 years on average.

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.
