You stop watching your yard wash away every time it rains. Stallings gets over 43 inches of rain a year—more than most of the country—and if your property has any slope at all, that water is taking your soil with it.
A properly built retaining wall stops that. It holds back soil, redirects water where it needs to go, and creates flat, usable space where there wasn’t any before.
You’re not just fixing an erosion problem. You’re adding square footage to your yard that you can actually use—for a patio, a garden, seating areas, or just a place where your kids can play without rolling downhill. And if you ever sell, buyers notice. Retaining walls can add around 15% to your property value because they solve real problems and look good doing it.
The difference between a wall that works and one that fails comes down to drainage and foundation prep. If water gets trapped behind the wall, it’s going to push, crack, and eventually collapse. That’s why every retaining wall installation in Stallings, NC that we build includes proper drainage systems and compacted base layers—not because it’s optional, but because it’s the only way it lasts.
Union Landscaping and Hardscape S Corp is a family-owned company based right here in Monroe. We’ve been building retaining walls, patios, and outdoor structures for homeowners across Union County, and we know the soil conditions, the clay challenges, and the drainage issues that come with this area.
When you call us, you’re talking to the people who will actually be on your property doing the work. We’re not a franchise or a national chain. We’re local, and we show up when we say we will.
Every retaining wall we install is custom-built for your yard. We don’t use cookie-cutter designs because no two properties are the same—especially in Stallings, where soil composition and slope vary from street to street.
First, we come out to your property and look at the slope, the soil, and where water is going when it rains. We measure, take notes, and talk through what you’re trying to accomplish—whether that’s stopping erosion, creating a flat patio area, or just keeping your driveway from washing out.
Then we design the wall. That includes choosing the right material—concrete retaining wall blocks, natural stone, or another option depending on your budget and the look you want. We also plan the drainage system, because without it, the wall won’t last.
Once you approve the plan, we start with excavation. We dig down to stable soil, compact the base, and lay the foundation. This part isn’t visible when we’re done, but it’s the most important step. A retaining wall is only as strong as what’s underneath it.
After that, we build the wall itself—course by course, checking level and alignment as we go. We install drainage pipes and backfill with gravel so water can escape instead of building pressure. Finally, we compact the soil, clean up the site, and walk you through what we did.
The whole process usually takes a few days to a week depending on the size of the wall. And when we’re done, you’ll have a structure that’s built to handle North Carolina weather for decades.

Every retaining wall we build in Stallings, NC includes a full drainage system. That means perforated pipes, gravel backfill, and proper grading so water doesn’t get trapped behind the wall. This isn’t an upgrade or an add-on—it’s standard, because it has to be.
We also handle permits if your wall is over the height threshold that requires one. Stallings has specific regulations, and we know what they are. You won’t get halfway through the project and find out you needed approval.
You’ll get a compacted base that goes below the frost line and prevents settling. We use retaining wall blocks or stone that’s rated for structural use, not decorative pavers that aren’t designed to hold back soil. And we build in a slight backward lean—called batter—so the wall naturally resists the pressure from the earth behind it.
If your yard has clay soil, which most properties in this area do, we adjust our approach. Clay holds water and expands when it’s wet, which creates extra pressure. That means more robust drainage and sometimes additional reinforcement depending on the wall height.
The goal is simple: a retaining wall that does its job for 50 to 100 years without cracking, leaning, or failing. That’s what you’re paying for, and that’s what you’ll get.
Most retaining wall projects in the greater Charlotte area, including Stallings, run between $40 and $50 per square foot. That price includes materials, labor, excavation, drainage, and cleanup.
If you’re looking at a small garden wall that’s 20 feet long and 3 feet tall, you’re talking about 60 square feet—so somewhere between $2,400 and $3,000. A larger wall that’s 50 feet long and 4 feet tall would be closer to $8,000 to $10,000. Most contractors, including us, have a minimum project size of around $2,500 because smaller jobs still require the same equipment, permits, and prep work.
The final cost depends on the material you choose, the height of the wall, and how much excavation is needed. Concrete retaining wall blocks are usually the most affordable. Natural stone costs more but has a different look. If your yard has tough access or requires a lot of grading, that can add to the price too.
We give you a clear estimate up front so there are no surprises halfway through the job.
It depends on the height. Stallings requires a permit for retaining walls over a certain height—typically around 4 feet, though the exact threshold can vary depending on the wall’s location and whether it’s supporting a load like a driveway or structure.
If your wall is shorter and purely decorative or for landscaping, you may not need one. But if it’s holding back a significant amount of soil or if it’s near a property line, a permit is usually required.
We handle this for you. Before we start any retaining wall installation in Stallings, NC, we check with the local building department to confirm whether a permit is needed. If it is, we pull it and make sure the wall is built to code.
Skipping the permit process might save time up front, but it can cause major problems later—especially if you try to sell your home and the buyer’s inspector flags an unpermitted structure. It’s not worth the risk.
Concrete retaining wall blocks are the most common choice because they’re strong, affordable, and come in a lot of styles. They interlock, which makes the wall more stable, and they’re designed specifically for this kind of work.
Natural stone is another option if you want a more custom look. It costs more and takes longer to install, but it has a timeless appearance that some homeowners prefer. Stone also handles the freeze-thaw cycles we get in North Carolina without cracking.
Timber walls are less common now because wood rots over time, especially in our climate. Treated lumber lasts longer than untreated, but even the best wood won’t hold up as long as block or stone.
The right material depends on your budget, the height of the wall, and the look you’re going for. For most residential projects in Stallings, concrete blocks or natural stone are the way to go. Both are durable, low-maintenance, and built to last decades if installed correctly.
Most residential retaining walls take between three and seven days to complete, depending on the size and complexity of the project. A simple garden wall might be done in a couple of days. A larger wall with multiple tiers, stairs, or difficult access can take a full week or more.
The timeline includes excavation, base prep, wall construction, drainage installation, backfilling, and cleanup. We don’t rush through any of those steps because each one matters.
Weather can affect the schedule too. If it rains heavily during excavation or base prep, we have to wait for the ground to dry out before we can continue. Trying to compact wet soil or pour gravel in standing water doesn’t work—it just leads to settling and failure down the road.
We’ll give you a realistic timeline before we start and keep you updated if anything changes. The goal is to finish on schedule without cutting corners.
A retaining wall can help with drainage, but it’s not a drainage solution by itself. If water is pooling in your yard, the issue is usually related to grading, soil compaction, or where runoff is being directed.
That said, when we build a retaining wall, we always include drainage features—perforated pipes, gravel backfill, and weep holes—so water doesn’t build up behind the wall. Those features move water away from the structure and prevent hydrostatic pressure, which is what causes walls to crack and lean.
If your yard has standing water issues, we can address that as part of the project by regrading the area, adding French drains, or adjusting the slope so water flows where it’s supposed to go. Sometimes the retaining wall itself creates an opportunity to fix drainage problems because we’re already excavating and moving soil.
The key is to look at the whole picture. A wall that holds back soil but doesn’t manage water isn’t going to solve your problem. We design every project with both in mind.
A well-built retaining wall should last 50 to 100 years. The difference between a wall that lasts and one that fails in five years comes down to three things: the foundation, the drainage, and the materials.
The foundation has to be solid. That means excavating down to stable soil, adding a compacted gravel base, and making sure the first course of block or stone is level and secure. If the base shifts or settles, the whole wall goes with it.
Drainage is just as critical. Water is the enemy of every retaining wall. If it gets trapped behind the wall, it creates pressure that will eventually crack or push the structure over. Every wall we build includes drainage pipes and gravel backfill so water can escape.
Materials matter too. Retaining wall blocks and stone that are rated for structural use will hold up. Decorative pavers or thin veneers won’t. And in Stallings, where we deal with clay soil and heavy rain, using the right materials isn’t optional.
If your wall was built with all three of those things in place, it’ll be standing long after you’ve moved on. If any of them were skipped, you’ll know within a few years.
