That slope washing out after every storm isn’t just annoying. It’s costing you usable space, killing your landscaping, and creating standing water that breeds mosquitoes and threatens your foundation.
A properly built retaining wall in McAlpine, NC changes that. You get flat, usable areas where there used to be mud and runoff. Your soil stays put. Water drains where it’s supposed to go.
The clay soil around McAlpine makes this even more critical. Without the right grading and drainage behind your wall, you’re looking at failure within a few years. We’ve seen it dozens of times—DIY jobs that buckle, tilt, or collapse because the water had nowhere to go.
When it’s done right, you’re looking at 50 to 100 years of performance. That’s what concrete retaining wall blocks and proper installation get you. No rot like wood. No constant maintenance. Just a structure that holds, drains, and lasts.
Union Landscaping and Hardscape S Corp has been serving McAlpine, NC and the Monroe area since 2021. We’re a family-owned company, and the people who answer your call are the same ones running the equipment on your property.
We’ve built retaining walls on every type of terrain McAlpine throws at us. Steep slopes, heavy clay, properties that flood every spring. The solutions that work here don’t always match what you see online or in other states.
That local knowledge matters when you’re dealing with North Carolina weather and soil that shifts. We size the footer correctly, install drainage that actually works, and use retention wall blocks that can handle the freeze-thaw cycles and summer storms you get in Union County.
First, we walk your property and talk through what you’re dealing with. Where’s the water going? What’s eroding? What do you want to use the space for once it’s level?
From there, we handle the engineering if your wall needs it—anything over four feet usually does in McAlpine, NC. We pull permits, work with engineers, and make sure everything’s up to code before we dig.
The install starts with excavation and a compacted base. This is where most failures happen, so we don’t cut corners. Then we set the first course of retaining wall blocks perfectly level—everything above it depends on that foundation.
As we build up, we’re installing drainage behind the wall. Usually that’s a French drain with gravel backfill, sometimes fabric, depending on your soil. The goal is to keep hydrostatic pressure from building up and pushing the wall forward.
Once the block wall retaining wall is up, we backfill, compact, and finish the grade. If you’re adding a patio, fire pit, or other hardscape services on top, we tie it all together so it looks intentional, not pieced together.
Ready to get started?
You’re getting a wall that’s engineered to stay in place. That means proper footing depth, the right block for the height, and drainage that keeps water from pooling behind it.
Most residential retaining walls in McAlpine, NC run between three and six feet tall. Taller than that, and you’re into engineered territory with geogrid reinforcement and stamped plans. We handle that process if your site needs it.
The materials matter more than most people realize. Concrete retaining wall blocks outlast wood by decades and don’t need the same level of maintenance. They also handle McAlpine’s clay soil better because they’re not absorbing moisture and expanding like treated lumber does.
You’re also getting soil erosion prevention that actually works. Once the wall is in and the drainage is installed, your yard stops washing into the street or your neighbor’s property. That saves you money on mulch, plants, and the headache of fixing the same problem twice a year.
And if you’re adding outdoor living spaces—patios, fire pits, pergolas—we design it all to work together. The retaining wall becomes part of the overall layout, not just a fix for a problem area.
Most retaining walls in McAlpine, NC run between $25 and $40 per square foot. That price moves depending on wall height, total length, how bad the soil conditions are, and what finish you want on the block.
A basic three-foot wall with standard retaining wall blocks is going to land on the lower end. A six-foot wall with curves, steps, and premium finishes will cost more. Accessibility matters too—if we can’t get equipment back there, labor goes up.
Drainage adds to the cost but skipping it isn’t an option. A wall without proper drainage will fail, and then you’re paying twice. We include French drains and backfill as part of the install because it’s the only way to build something that lasts.
If your wall is over four feet, you’ll need engineering and permits. That adds some cost upfront but keeps you legal and ensures the wall is actually safe. We help coordinate that so you’re not figuring it out on your own.
Most residential retaining wall installations in McAlpine, NC take between three and seven days, depending on size and site conditions. A straightforward 30-foot wall on flat ground with good access moves faster than a tall, curved wall on a steep slope with limited equipment access.
Weather plays a role too. If it rains halfway through, we’re not pouring base or setting block in mud. McAlpine’s clay soil doesn’t drain fast, so we wait until conditions are right to keep the foundation solid.
The timeline also depends on whether we’re doing just the wall or tying in other hardscape services like patios or grading. If you want the whole outdoor living space done at once, we’ll map that out upfront so you know what to expect.
We don’t rush the job to hit a deadline. The base has to be compacted right, the blocks have to be level, and the drainage has to be installed correctly. Doing it fast doesn’t help you if it fails in two years.
It depends on the height and location. In McAlpine, NC and Union County, retaining walls over four feet typically require a permit and engineered plans. Walls near property lines or easements may also need approval regardless of height.
If your wall is holding back a significant amount of soil or if it’s supporting a structure like a patio or driveway, engineering is usually required. The county wants to make sure it’s safe and won’t fail or affect drainage on neighboring properties.
We handle the permit process if your project needs it. That includes coordinating with engineers, submitting plans, and making sure inspections happen on schedule. You don’t have to figure out who to call or what forms to fill out.
Even if a permit isn’t required, building it to code is still the right move. A wall that meets engineering standards lasts longer and performs better, whether the county requires a stamp or not.
Concrete retaining wall blocks are the best option for most projects in McAlpine, NC. They last 50 to 100 years, handle the clay soil and weather well, and don’t rot or warp like wood does.
Wood retaining walls might be cheaper upfront, but they only last 10 to 15 years before they start failing. Treated lumber absorbs moisture, expands, and eventually rots out. In McAlpine’s humid climate, that happens faster than in drier areas.
Stone is another option, but it’s more expensive and usually requires mortar and a concrete footer. It looks great, but the cost and complexity go up. For most residential projects, segmented concrete blocks give you the best balance of cost, durability, and appearance.
The specific type of retention wall blocks depends on your wall height and design. Some blocks interlock and don’t need mortar. Others are pinned or use geogrid for taller walls. We match the block to the job so you’re not over-building or under-building.
A retaining wall can fix drainage problems, but only if it’s designed and installed with drainage in mind. The wall itself doesn’t solve water issues—the grading and drainage system behind it does.
Most retaining wall failures happen because water builds up behind the wall and pushes it forward. That’s called hydrostatic pressure, and it’s why proper backfill and drainage are critical. We install French drains, use gravel backfill, and grade the soil so water moves away from the wall instead of pooling behind it.
If your yard has standing water, erosion, or runoff problems, we look at the whole site—not just where the wall goes. Sometimes that means regrading areas uphill from the wall or adding drainage elsewhere on the property.
A well-built retaining wall in McAlpine, NC stops soil erosion, creates level space, and manages water correctly. But it’s not a magic fix if the rest of the drainage is ignored. We design the system to work together so you’re not dealing with the same problems after we leave.
Yes, and it’s one of the best ways to maximize your outdoor living spaces in McAlpine, NC. A retaining wall creates the flat area you need, and then we build the patio, fire pit, or seating area on top of it.
The key is planning it all upfront. If we know you want a paver patio or fire pit on the upper level, we design the wall and grading to support that. The base has to be compacted correctly, and the transition between the wall and the patio has to be seamless.
This approach turns a sloped, unusable yard into a functional outdoor space. You get a level area for furniture, a fire pit for gatherings, and a retaining wall that ties it all together visually.
We handle the full scope—retaining wall installation, grading, patio pavers, fire pit construction, and any other hardscape services you want. That way everything is coordinated, and you’re not hiring three different companies to piece it together.
