At Gramm Outdoor Contracting, we specialize in designing and installing durable, functional, and visually appealing retaining walls that enhance both residential and commercial landscapes.
Retaining walls are essential for preventing soil erosion, managing slopes, and creating level spaces for outdoor living. Below, we’ll explore the different types of retaining walls available and their benefits.
Types of Retaining Walls
Gravity Retaining Walls
How They Work:
Gravity retaining walls work by relying on their own weight to resist soil pressure and maintain stability. These walls are often built with heavy materials like stone, concrete, or brick to provide the necessary mass. They are often called dry stack retaining walls because no mortar is used to hold the blocks together.
Benefits:
- Simple construction with minimal reinforcement
- It can be built using natural stone for an aesthetically pleasing look
- Ideal for shorter walls under 4 feet
Anchored Retaining Walls
How They Work:
Anchored retaining walls use cables or rods driven deep into the soil and secured with anchors to provide additional stability. These walls are beneficial in areas where space is limited or where heavy loads must be retained.
Benefits:
- Ideal for steep slopes and high walls
- Provides strong reinforcement for areas with high lateral pressure
- Can be used with various facing materials for a customized look
Cantilevered Retaining Walls
How They Work:
Cantilevered retaining walls feature a base slab and a thin vertical stem that work together to leverage the weight of the backfilled soil. Typically constructed from reinforced concrete, these walls can support significant loads.
Benefits:
- Requires less material than gravity walls, making them cost-effective
- Suitable for medium to large-scale projects
- Long-lasting structural integrity
Sheet Pile Retaining Walls
How They Work:
Sheet pile retaining walls consist of long, thin sections of steel, vinyl, or wood driven deep into the ground. They are commonly used in soft soils or waterfront areas.
Benefits:
- Efficient for space-constrained areas
- Ideal for temporary or permanent structures
- It can be installed quickly with minimal excavation
Why Retaining Walls Are Important
Retaining walls serve functional and aesthetic purposes, making them a valuable investment for any landscape.
- Erosion Control: Prevents soil displacement, especially on sloped properties.
- Structural Support: Provides stability to landscapes with uneven terrain.
- Increased Usable Space: Transforms slopes into functional terraces and outdoor spaces.
- Improved Drainage: Helps direct water flow to prevent flooding and foundation damage.
- Aesthetic Appeal: Enhances property value with customized designs and materials.
Common Retaining Wall Materials
Choosing the right material is crucial for the durability and aesthetics of your retaining wall. Here are some popular options:
- Concrete Blocks: Strong, durable, and available in various styles.

Pittsburgh's hilly terrain and frequent rain create beautiful landscapes, but they also come with unique challenges. Erosion, runoff, and steep slopes can make yard maintenance difficult and even pose risks to your property. For many homeowners, retaining walls are a practical solution that balances function and form. Whether you're hoping to level your yard for a garden, support a new patio, or prevent water damage, choosing the right type of retaining wall is essential. This guide explains the most common types of retaining walls, when each works best, and how factors like soil, space, and budget should guide your decision. Why Retaining Walls Are Common in Pittsburgh Retaining walls serve as structural solutions for managing soil on uneven ground. In neighborhoods like Mt. Lebanon, Brookline, and Upper St. Clair, where elevation changes are part of the landscape, homeowners frequently install these walls to prevent erosion, manage water flow, or make outdoor areas more usable. But their value goes beyond utility. A thoughtfully designed retaining wall can create garden beds, define outdoor living spaces, and add architectural interest. As with any home improvement project, the key to long-term satisfaction is selecting a wall type that fits your goals and site conditions. 
Adding a pond to your backyard can bring peace, beauty, and wildlife to your outdoor space. Whether you want a small koi pond or a larger water feature, proper planning and compliance with local rules is essential. If you live in Pittsburgh or the South Hills, here is what you need to know before you begin backyard pond construction. Why Pond Regulations Matter Backyard ponds are considered landscaping features, but they can affect water flow, drainage, and even wildlife. Most municipalities have zoning, stormwater, and safety rules that may apply to pond construction. These rules are designed to prevent flooding, protect public safety, and ensure that ponds do not interfere with existing infrastructure or natural habitats. Working with experienced pond builders in Pittsburgh can help ensure your project is compliant and stress-free. A professional pond contractor in Pittsburgh will understand the permitting process and how to design a pond that meets local codes while enhancing your property. Pond Regulations in Pittsburgh In the City of Pittsburgh, small decorative ponds installations are allowed as accessory structures. However, if you are digging more than five feet deep or moving over 50 cubic yards of earth, you must obtain a Land Operations Permit. If your pond includes pumps, lighting, or other electrical systems, an electrical permit will likely be required as well. Pittsburgh also enforces strict stormwater management guidelines. If your project disturbs more than 10,000 square feet of land or adds over 5,000 square feet of impervious surface, a stormwater management plan is mandatory. This plan must demonstrate how your pond will handle runoff without overwhelming the city's combined sewer system. Even if your pond is below these thresholds, it is important to manage overflow responsibly to avoid erosion or flooding on neighboring properties. If your yard is located in a floodplain or near a steep slope, your pond project may also trigger additional review. Pittsburgh’s zoning code includes overlay districts to address landslide-prone areas and flood control. Before building, check if your property is subject to these designations. Pond Regulations In Mt. Lebanon In Mt. Lebanon, backyard ponds are permitted as accessory uses in residential zones. You must follow placement rules, typically requiring ponds to be located in the rear yard and at least 10 feet from property lines. If your pond is deeper than 24 inches, it may be subject to the same safety and fencing requirements as a pool. A building permit is generally required for such features. Additionally, a grading permit is needed for projects disturbing more than 500 square feet of soil. This includes excavation for a pond or surrounding landscaping features. Mt. Lebanon requires erosion and sediment control measures during construction to prevent runoff and protect storm drains. If your project increases impervious surface or alters water flow, you may also need to submit a stormwater plan in compliance with the municipal stormwater ordinance. Pond Regulations In Bethel Park Bethel Park allows residential ponds, but local code mandates a zoning permit for any project that changes surface grading or drainage. A small ornamental pond with minimal excavation may not require a full building permit, but you must confirm this with the Community Development office. If your pond includes a hard liner, concrete edging, or other impervious features, it could be subject to stormwater management rules. The municipality follows Pennsylvania's stormwater laws and integrates DEP regulations, including Chapter 105, which governs dam safety and waterway management. Projects near wetlands or natural watercourses require state DEP approval. Homeowners should avoid disturbing these sensitive areas or rerouting water unless explicitly permitted. Standing water that becomes stagnant can be cited as a public health nuisance, so aeration or circulation features are recommended. Pond Regulations In Upper St. Clair Upper St. Clair treats backyard ponds as accessory structures. They must follow placement and size rules based on the property’s zoning. Any land grading requires a permit. If your pond alters the contour of your yard, a grading permit is mandatory. The township has a low threshold for stormwater review. If your pond is lined or constructed in a way that creates more than 400 square feet of impervious area, you must submit a formal stormwater management plan. This plan must demonstrate how excess water will be retained or infiltrated on-site. Homeowners should also consider safety. While the township does not regulate ponds as pools, any water feature deeper than two feet should be treated with caution. Fencing or child-proof barriers are strongly recommended to reduce risk. Pond Regulations In South Park Township South Park Township requires a permit for any significant land disturbance. Digging a pond basin, even for a small garden pond, may qualify as grading and require approval. The township follows updated stormwater regulations. Projects that change how water flows across your property must include measures to handle runoff. This might include gravel trenches, bioswales, or drainage basins. Failure to manage water properly can result in fines or mandatory remediation. South Park also requires that ponds do not create health hazards. A poorly maintained pond with algae or mosquitoes could violate local nuisance ordinances. Choosing the right depth, filtration, and aquatic plants can help keep your pond healthy. Be Sure To Check Local Resources We have taken the time to spell out some of the regulations that you may encounter. Upon your decision to hire us as a pond builder, we will adhere to all regulations in your local region. For piece of mind, you may want to read further on your local government's website or call into the code enforcement office. We are familiar with local regulations for many cities in the greater Pittsburgh area and consult each for the correct permits before a job is started. Benefits of Small Backyard Ponds with Waterfalls Small backyard ponds with waterfalls are a popular choice for homeowners in Pittsburgh and the South Hills. These features offer visual interest, calming sound, and practical benefits. The sound of falling water creates a relaxing atmosphere and can help mask noise from nearby roads or neighbors. Waterfalls also help circulate the pond, reducing the risk of algae growth and mosquito breeding. A well-designed pond with a waterfall can attract birds, butterflies, and beneficial insects. It can also support aquatic plants and fish, creating a vibrant mini-ecosystem. With professional pond installation service, these features are easy to maintain and provide lasting beauty throughout the seasons. Why Hire a Professional Pond Contractor in Pittsburgh A professional pond contractor in Pittsburgh does more than dig a hole and fill it with water. Reputable pond builders in Pittsburgh will evaluate your yard’s slope, soil type, drainage, and exposure to sunlight. They can design a system that includes proper liners, skimmers, pumps, and filters to keep your water clean and safe. They will also help you avoid common mistakes, such as building too close to utility lines or underestimating overflow capacity. Their experience with local permitting processes ensures your project moves forward without delays. A professional pond installation service will also consider aesthetics and ecology.

Designing a new patio is an exciting step in transforming your outdoor space. Whether you're planning a cozy backyard escape or a spacious area for entertaining, the materials you choose will play a critical role in how your patio looks, feels, and holds up over time. For many homeowners, the decision often comes down to two popular options: concrete pavers or natural stone. At Gramm Outdoor Contracting, we excel constructing at a variety of patio types , and we know there's no one-size-fits-all answer. Both concrete paver and natural stone patios bring unique advantages to the table along with a few trade-offs. So, how do you choose the right one for your project? In this guide, we will explain the main differences between these two hardscaping solutions, helping you understand what works best for your home's style, budget, and long-term goals. The Right Patio Material for Your Outdoor Space When you start planning a patio project, there's more to consider than looks. Your lifestyle, local climate, long-term maintenance expectations, and budget all factor into the decision. Some homeowners are drawn to the uniformity of concrete pavers, while others love the natural beauty and character of stone. Each option has its place—and understanding how they perform in different situations can help you make a decision you'll feel confident about. Durability and Longevity in Real-world Conditions Outdoor patios are constantly exposed to the weather, and durability is a key concern especially in areas like Western Pennsylvania, where we deal with hot summers, freezing winters, and everything in between. Concrete pavers are designed to be tough. They're manufactured to uniform standards, which means they often resist cracking and shifting better than poured concrete slabs. If a paver does get damaged, the fix is usually straightforward: remove and replace the individual piece. This makes repairs simple and keeps your patio looking fresh for years. Natural stone, on the other hand, offers incredible strength that comes straight from the earth. Materials like flagstone, slate, or granite have stood the test of time for centuries. That said, not all stones are created equal—softer stones like limestone may wear faster or be more susceptible to chipping in high-traffic areas. But when appropriately installed, a natural stone patio can easily last decades with minimal issues. Both options can perform well over time, but if easy repairs and uniform wear are essential to you, pavers might be the more practical choice. If you're aiming for a long-lasting investment that ages gracefully, natural stone delivers timeless appeal and lasting performance. Pavers VS. Natural Stone: Style Matters Of course, how your patio looks is often one of the most significant factors in your decision. After all, this is a space where you'll relax, host gatherings, and enjoy your outdoor surroundings. Natural stone has an undeniable charm. Each piece is stunning and unique in color, texture, and shape, giving the finished patio a more organic and one-of-a-kind appearance. It's the go-to choice for rustic, classic, or upscale designs where natural beauty is the priority. From warm sandstone tones to the cool blues and grays of Pennsylvania bluestone, the range of options is impressive and sophisticated. Concrete pavers offer something different versatility. Because they're manufactured, they come in a wide array of colors, shapes, and patterns. Want a herringbone pattern that mimics old-world brick? Done. Do you prefer a clean, minimalist design for a modern space? That's easily achieved with sleek, square pavers in muted tones. Pavers can even mimic the look of natural stone if you're drawn to that aesthetic but want a more budget-friendly option. In the end, your design goals will help guide you. If you're going for a natural, earthy vibe with lots of texture and variation, natural stone might be the way to go. If you're focused on symmetry, color control, or a contemporary feel, concrete pavers can deliver stunning results. Comparing the Costs: Short-Term and Long-Term Budget is always a big part of any project, and understanding the cost differences between these materials will help you plan accordingly. Concrete pavers are typically the more affordable option, both in terms of material and labor. This makes them an excellent choice for larger patios or for homeowners who want to stretch their budget without sacrificing style. Natural stone comes with a higher upfront price tag. The stones themselves are more expensive, and because of their irregular shapes and sizes, installation takes more time and expertise. Cutting and fitting the stone can be labor-intensive, especially if you're aiming for a seamless or intricate layout. But the cost isn't just about the initial installation—long-term expenses matter, too. Concrete pavers may require occasional sealing or joint sand replacement. While individual pavers are easy to swap out, maintenance can add up if the patio isn't installed or maintained properly. Natural stone, though more durable in some ways, might need sealing depending on the type of stone and exposure, mainly to prevent stains or moisture absorption. If you want a great-looking patio without a hefty investment, concrete pavers are a wise choice. If you're willing to invest more upfront for a luxurious, enduring surface, natural stone offers exceptional value over time. Maintenance Realities: What to Expect Year After Year No matter which material you choose, your patio will need some level of upkeep to stay in great shape. Concrete pavers usually benefit from sealing every few years to maintain their color and protect against stains. Weeds can sometimes grow between the joints, but using polymeric sand or sealants during installation helps prevent this. If a paver shifts or cracks, it's easy to pop it out and replace it without disturbing the rest of the patio. Natural stone tends to be more forgiving when it comes to minor wear and tear. It weathers beautifully, often developing a soft patina over time. Some stones—particularly porous ones like sandstone or limestone—may need sealing to guard against staining, especially if your patio is near trees, grills, or outdoor kitchens. Cleaning is usually simple with water and a soft brush, but harsher chemicals should be avoided to protect the stone's surface. In general, both options are manageable with regular maintenance, but natural stone may offer a bit more resilience in the long run—assuming the right type is chosen and installed correctly. Why Professional Installation Matters When it comes to building a patio, installation is just as important as the materials you choose. A well-installed patio not only looks better but also performs better—resisting shifting, cracking, and drainage issues over time. While some homeowners may consider tackling a patio as a DIY project, it's essential to understand the complexity involved and why hiring a professional often leads to better, longer-lasting results. Concrete pavers are often seen as more manageable for DIY installation due to their consistent size and shape. However, even with pavers, proper base preparation, leveling, and joint filling are essential. Skipping or misjudging any of these steps can result in uneven surfaces, poor drainage, or premature wear. What seems like a straightforward project can quickly become more labor-intensive and technically demanding than expected. Natural stone , on the other hand, is rarely recommended for DIY installation. Because each piece varies in size and thickness, fitting and leveling them requires skill, specialized tools, and a strong eye for design. Creating a stable, seamless surface out of irregular stones is an art in itself—one best handled by experienced hardscaping professionals. In both cases, professional installation brings significant benefits. Experts know how to grade the area for water runoff properly, compact the base layers to prevent future settling, and align patterns or stone layouts for a cohesive, polished appearance. The result is a patio that not only looks great but also stands the test of time. While DIY projects can be rewarding, patios are a long-term investment in your property. Trusting a professional ensures that investment pays off—with fewer headaches, reduced maintenance, and a flawless finish you'll enjoy for years to come. Installing Patio Materials to Meet Your Goals Each material shines in different scenarios. Here are a few examples to help you narrow things down: Concrete pavers are a great fit if you: Want a clean, modern look with lots of pattern and color choices Are you working within a specific budget Need a quick installation timeline Prefer a material that's easy to repair or update over time Natural stone is ideal if you: Are aiming for a timeless, elegant design Appreciate natural variation and organic textures Are you building a high-end or rustic outdoor space Don't mind investing more for lasting beauty and character.
