"Very nice work. ð . Tom was super easy to work with. We had just had our driveway re-sealed so we asked if they could work without using the driveway. They unloaded the truck by hand. They took care of our property and we really appreciate them!!"

"We hired Palmer Foundations and Flatwork to pour our foundation, porches, chopped walls, and floors, and let me just say ? they absolutely knocked it out of the park! From start to finish, their team was professional, efficient, and incredibly skilled. Every single detail was executed with precision, and the final result truly exceeded our expectations. Not only does everything look phenomenal, but it?s also solid, clean, and built to last. They showed up when they said they would, communicated clearly throughout the project, and worked hard even through some tough conditions to get the job done right. If you?re looking for a concrete crew that takes pride in their work and delivers flawless results, look no further than Palmer Foundations and Flatwork. We couldn?t be happier with how everything turned out. Highly, highly recommend!"

"Jim and his guys did a great job on my deck. We had multiple bad spots (bad boards and posts) they fixed. We also had water leaking into the house and our below deck 3 season room. He found the source and meticulously fixed it. Very professional, on time and cleaned up when done. Highly recommend."

Retaining Wall Installers questions, answered by experts

Poured concrete is often the cheapest material for a retaining wall, costing around $6 to $8 per square foot. Other budget-friendly options include vinyl and landscaping timbers, which range from $10 to $15 per square foot; landscaping timbers are particularly well-suited for DIY projects. Untreated timber and railroad ties are a step up in price, starting at $15 to $25 per square foot. Natural stones can also be a cost-effective choice if you can source them from your own property, but they can be expensive to purchase. High-end materials like steel are typically the most expensive but offer superior durability and aesthetics.

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

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.

Yes, including patterns, finishes, and plant integration for aesthetic enhancement.

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like.
