New Retaining Wall Construction
We build new segmental retaining walls using proven, engineered systems. Segmental block walls are strong, durable, and easy to maintain. They're also flexible in design, cost-effective, and ideal for residential landscapes.
We use Keystone® retaining wall systems for most of our projects. These are pre-engineered systems that don’t require full custom design plans unless the wall exceeds certain heights or loads. If your wall needs to be engineered, we’ll coordinate with a licensed engineer to ensure it meets local codes and safety standards.
Do You Need a Permit for a Retaining Wall?
In Jackson, Hall, and Gwinnett Counties, the rules are fairly consistent:
-
- Walls under 3 feet typically don’t require a permit
- Walls 3 feet or higher generally do require a permit
- Walls over 6 feet often require both a permit and engineered plans
- Some neighborhoods may have HOA rules or property covenants
We’ll handle this for you. When we visit your property, we’ll assess the wall height, load (surcharge), and site conditions to determine if permitting or engineering is needed.
Why Drainage Is So Important
Poor drainage is the #1 reason retaining walls fail. We see it all the time—walls that lean, bulge, or collapse because they weren’t built to handle water.
When water builds up behind a wall, it creates hydrostatic pressure. Without proper drainage, this pressure pushes against the wall and eventually causes failure.
We build every wall with drainage in mind. Depending on your project, we may install:
-
- Gravel backfill
- Perforated drain pipes (French drains or weep drains)
- Filter fabric
- Geo-grid for soil reinforcement
Our goal is to relieve water pressure and make sure your wall lasts for years.
What Is a Retaining Wall Surcharge?
A surcharge is any weight pressing down on or behind a wall besides the soil. This includes things like:
-
- A driveway, RV pad, or parked vehicle
- A fence on top of the wall
- A tiered wall system
- Heavy landscaping or patios
Walls with surcharges need to be reinforced. We may use geo-grid layers that tie back into the slope to stabilize the wall and distribute the load.
Materials We Use
We work with materials that perform well in Georgia’s climate and terrain:
-
- Segmental concrete block (Keystone®)
- Natural stone
- Large landscape boulders
Each has its own look, cost, and best use case. We’ll help you choose the right material for your property and budget.
Our Retaining Wall Construction Process
-
- On-site consultation – We inspect your slope, soil, and drainage.
- Project scope – We determine height, length, access, and material needs.
- Permit review – If your wall requires engineering or permits, we handle it.
- Surcharge check – We assess any loads on or behind the wall.
- Material selection – You pick the style and finish you want.
- Written estimate – You get a clear, detailed quote with no surprises.
No two walls are the same. The slope, soil type, and access to your yard all impact the final design and price. We provide accurate pricing only after a site visit.
What Does It Cost To Build Retaining Walls?
Retaining walls can vary in price depending on the size, scope, length, height, and the materials chosen. Larger walls will need to be engineered which can add to the cost.
Smaller Garden Walls
$5000 - $8000
This would be for a small garden wall (under 2 feet high) to surround a small garden or to surround a small landscaping bed.
Medium Sized Walls
$10,000 - $25,000
This would be for a medium sized wall up to 4 feet high. Installed with drainage and geo-grid so it lasts.
Large Retaining Walls
$30,000 - $100,000+
This would be a ballpark cost for a very large or tiered retaining wall or multiple wall with courses that are 4 feet or higher
Retaining Wall Projects Can Include
A beautiful retaining wall isn't just for looks. They have an important job to do. Whether we're building a brand new retaining wall or replacing an existing retaining wall that has failed, there are a number of things we do.
Retaining Wall Repair Or Replacement
We specialize in rebuilding retaining walls that have failed and/or collapsed.
Retaining Wall Repairs
It's pretty common for us to get called out to repair an existing retaining wall that has collapsed or failed in some way. This could be an old wood retaining wall that is rotting away or a block wall that is bulging or on the verge of collapse if it has not collapsed already.
Typically we don't recommend "repairing" retaining walls. The wall has failed for a reason and that reason is typically poor construction or a poor choice of materials. When a wall has failed we will usually recommend tearing the wall out and replacing it. This would include demolition of the old wall, re-excavating the area to allow for proper base materials, installation of proper drainage, and proper backfill. Building it right is the more cost effective option in most situations.
Rebuilding Failed Retaining Walls
If your existing retaining wall has failed and needs to be replaced it's usually more cost effective to demolish the old wall, remove the materials, re-excavate the site, install a proper base, geo-grid if necessary, install drainage, and build the retaining wall properly.
We specialize in rebuilding retaining walls that have failed and would be happy to provide you with a consultation if you have a wall that you believe needs to be replaced.

The pictures speaks for itself. Matt and Kelly did a miracle on my yard. At first I was nervous and was asking a lotta Questions. Kelly said to me, “trust the process. Trust me, it’s not gonna be bad as it looks when we’re done.” They were very professional and detailed with the information about their project. And I gotta say. They did excellent💯 They put up a retaining wall with a French drain and also pushed my hill back a little further, giving me more yardage at the bottom. We have been getting so many compliments about how good our yard looks now. And I couldn’t agree more. I highly recommend this landscaping company. They know their work. And you won’t be disappointed. As you can see with my before and after pictures. Thanks to Matt and Kelly. I have a lotta yard. More than what I thought I actually had☺️and I’m so happy and excited. I have a lotta ideas that I wanna do to my backyard now.
"The landscaping team did an exceptional job on the retaining wall, it looks fantastic and is clearly built to last - very impressed with their attention to detail and professionalism throughout the entire project!". Razor Sharp demonstrates a strong commitment to customer satisfaction through efficient scheduling, detailed project work, and a focus on personalized landscape designs. I would highly recommend them on any project you have in mind. Our backyard went from having no space for our animals, to having a whole new yard for them to run and play in. The addition of sod and flowers gave our home a whole new look! Thank you Razor Sharp for the wonderful yard addition you have given us and our pets.
If you are like me, our weekends are swamped with youth sports and busy schedules. We typically do a lot of projects ourselves, but for a retaining wall and gravel rock around the back deck it would have taken us all summer to do ourselves. We are so glad we called Razor Sharp Lawn and Landscape, they knocked it out in 3 days and could not be happier with the results the team did. Their team is polite and accommodating to getting our backyard in order I can't thank them enough. They are way more creative than me and do the job right. Their pricing hit our budget perfectly and didn't try to oversell the job. They are honest, have all the right tools to complete large jobs quickly. If you are in the same boat as I was, I encourage you to check them out. You will not be disappointed!
10/10. I had an erosion issue and wanted to make it pretty and functional. Needed a retaining wall and pavers. Being in Real Estate we see all kinds of work and craftsmanship. I work with contractors 24/7. Matt answered my call right away and came to estimate my project within 24 hours. He was knowledgeable and professional. The price was better than the 2 other quotes I received. He was prompt everyday during the project. No complaints from them even when I asked 100 questions. I will be using this company for all my lawn and landscape needs. Great job guys!!
These gentlemen did an amazing job and the quality of their work is commendable! We are so pleased with the retaining wall and the landscaping work they did and my husband and I highly recommend them.
Matt and his crew are simply the best! Do NOT use anyone else for your retaining wall needs! These are the guys to do it! They are timely, knowledgeable, quick to respond to my questions, and were completely honest with me and transparent about everything. They made sure they did the work right!
Working with Matt and his crew was a phenomenal experience for us. Matt is knowledgeable, kind, professional and very hard working. We had a retaining wall built and the area between this wall and our house was leveled and covered with multicolored river rock. We also had the edging around our trees in the backyard done-the result is more than amazing. We are grateful for a job very well done. We highly recommend Matt and his crew. Thank you!
