What’s Under Our Retaining Walls

All of our retaining wall installations in Nassau County are built to strict manufacturer specifications to ensure long-term strength and stability. Depending on the project design and soil conditions, we use either a stone or concrete footing as the base. For most Nassau County properties, a concrete footing is the preferred and most durable option. Additionally, we install filter fabric between the footing and the ground to prevent soil from mixing with the base material. This extra layer helps maintain proper drainage and reinforces the structural integrity of your retaining wall over time.

What Size Wall Do You Need?

The first step in any Nassau County retaining wall installation is removing any existing wall or structure. Retaining walls come in many sizes, depending on your property’s layout and needs. Smaller walls, typically 1–2 feet tall, are ideal for holding back garden beds or small sections of your lawn. Medium-sized walls around 3–4 feet tall provide greater support and definition, while larger walls over 4 feet—or even multi-tiered systems—are designed for managing steep slopes and creating level, usable spaces in your landscape.

Footings

The next step in our Nassau County retaining wall installation process is digging the footings. Footing depth and type vary depending on the size and purpose of the wall. For larger or load-bearing retaining walls, our team typically digs footings up to 3 feet deep and mixes concrete on-site for maximum strength. By this stage, our experienced retaining wall contractors have already evaluated your property’s conditions to determine the proper specifications. The first course of wallstone is then set directly into the concrete footing for stability, with a portion of it buried below ground to provide additional support and prevent shifting over time.

The Process as We Build Upward

Once the footing is complete, our Nassau County retaining wall contractors begin stacking each course of wallstone, securely gluing one layer to the next for stability. As the wall is built upward, we backfill behind it with clean drainage rock and install drainage pipes with exit spouts at the appropriate heights to direct water away from the structure. Proper drainage is one of the most important factors in preventing wall failure, and our experienced installers take great care at this stage. A layer of filter fabric is also added behind the drainage rock to keep soil from seeping into the system, ensuring long-term strength and reliability.

Specs

In some cases, depending on the height of your retaining wall and local Nassau County regulations, an engineer may be required to design and specify the wall for maximum strength and safety. Retaining walls can be built from several different materials, each offering unique benefits. One of the most cost-effective options is wood, such as railroad ties; however, these tend to deteriorate and fail over time. Wallstone systems that stack vertically are durable and visually appealing but are not as structurally strong as stepped retaining wall systems, which handle pressure more effectively. Our retaining wall installers recommend choosing materials that balance strength, longevity, and design appeal. Beyond their practical function, retaining walls also add texture, color, and depth to your landscape, transforming sloped areas into attractive, usable spaces.
