This makes brick a dependable, long-lasting option for outdoor walls in Maryland.
3. Concrete Block (Segmental Retaining Wall Blocks)
Durability
When made with quality materials, concrete blocks can endure for over a century. However, exposure to harsh conditions or the use of lower-quality materials can reduce their lifespan to about 50 years [14].
Maryland’s climate poses unique challenges for concrete blocks, particularly due to moisture and deicing salts. These elements are major contributors to freeze-thaw damage, which can significantly impact the durability of retaining walls [11]. A study conducted by the Maryland Department of Transportation in July 2001 reviewed 104 segmental retaining walls constructed before 1994. The study found that while only 7 percent of the walls were rated as poor or very poor, more than 50 percent showed signs of freeze-thaw damage [12].
"Walls located at parking lots or close to the roadway exhibited the most damage, due to increased amounts of snow accumulation and water runoff, therefore allowing for greater saturation, and exposure to deicing salts" [12].
To enhance durability, it’s wise to choose high-quality concrete blocks designed to withstand freeze-thaw cycles. Applying silane or siloxane coatings can help prevent moisture penetration, and incorporating proper drainage systems can further reduce damage caused by freezing and thawing [11].
Aesthetic Appeal
Segmental retaining wall blocks offer a wide range of design options while maintaining a clean and structured appearance. They come in various textures, colors, and sizes, making it easy to match them to any landscaping style. Their modular design allows for flexibility in construction, making it simple to create curves, corners, and walls of varying heights [13].
Unlike natural stone, concrete blocks provide consistent dimensions and uniformity, appealing to homeowners who prefer a modern, polished look. Many manufacturers even produce blocks that mimic the texture of natural stone, offering the best of both worlds: the aesthetic of stone with the precision and ease of concrete installation.
And the best part? These design perks come at a price point that won’t break the bank.
Cost Range
Concrete block walls are a cost-effective solution for Maryland homeowners. Installation costs typically fall between $15 and $30 per square foot for standard uses. Retaining wall applications range from $20 to $35 per square foot, while block fences cost $15 to $30 per square foot [15].
In Bethesda, Maryland, the cost of retaining walls can range from $16 to $50 per square foot, depending on the material used. Concrete blocks are generally on the more affordable end of this spectrum [16]. Factors like foundation requirements, reinforcement needs, and whether the wall is load-bearing can influence the final price [15].
Suitability for Maryland’s Climate
Concrete blocks are particularly well-suited to Maryland’s demanding climate. They hold up against extreme weather conditions and require minimal maintenance once installed properly [17]. From the hot summers to the icy winters and varying humidity levels, concrete blocks resist cracking, erosion, and other weather-related damage better than many alternative materials [19].
Given Maryland’s hilly terrain, retaining walls made from concrete blocks are especially useful for preventing soil erosion and managing water runoff in lawns and gardens [17]. Concrete’s strength also makes it easier to integrate effective drainage systems, which are essential for handling Maryland’s frequent rain and preventing water buildup that could weaken the wall over time [19].
Experts, such as Baltimore-based Detailz Construction, stress the importance of proper installation to ensure long-lasting performance. They highlight critical factors like "the grade of earth, the quantity of crushed stone needed to prevent hydrostatic pressure, footing sizes, and other considerations" [18]. Details such as weep holes, drainage systems, geogrid reinforcement, and properly compacted soil and stone behind the wall are essential for ensuring durability and preventing future issues [18].
4. Manufactured Stone Veneer
Durability
Manufactured stone veneer is built to handle Maryland’s tough weather conditions. It’s designed to endure extreme temperatures, heavy rain, and snow, while also resisting rot and insect damage. However, achieving this level of durability depends on proper installation. This includes thorough preparation of the substrate, correct flashing, and comprehensive waterproofing measures [20]. When installed correctly, products like Affinity Stone veneer panels can last over 50 years [21]. Brands such as Casa di Sassi even offer 50-year warranties against issues like blistering, peeling, flaking, delaminating, and cracking, provided installation guidelines are followed [20]. To manage moisture effectively, adding a drainage mat or furring strips to create an air gap between the veneer and the wall is crucial [22]. The result? A material that combines long-lasting performance with natural charm.
Aesthetic Appeal
Manufactured stone veneer captures the beauty of natural stone while offering consistent design quality. It can replicate virtually any natural stone style, from rugged fieldstone to refined limestone. Companies like Pro Landscapes MD use premium options such as El Dorado Stone [4] to craft decorative features that elevate the look of Maryland properties. Its uniform dimensions and polished appearance make it an excellent choice for those seeking a modern aesthetic with the timeless allure of stone. Plus, it integrates seamlessly into various architectural styles and landscape designs.
Cost Range
For those looking for a more affordable alternative to natural stone, manufactured stone veneer is a practical option. Material costs range between $4 and $20 per square foot, with installation adding another $6 to $24 per square foot [25]. This brings the total installed cost to roughly $10 to $35 per square foot [25]. For example, Casa di Sassi stone veneer is priced between $8 and $12.50 per square foot [23]. In contrast, natural stone can cost $35 to $50 per square foot for materials alone, with installation adding an extra $20 to $30 per square foot [23].
Suitability for Maryland’s Climate
Maryland’s unpredictable weather demands materials that can handle a variety of conditions, and manufactured stone veneer fits the bill. Its composition – cement, lightweight aggregates, and iron-oxide pigments [24] – makes it highly resistant to freeze-thaw cycles. Proper waterproofing further ensures that water won’t seep in, preventing issues like mold, mildew, and damage caused by freezing and expansion [20]. For optimal performance, installations should include a two-layer water-resistant barrier and proper flashing systems [20]. Thanks to its engineered resilience and moisture resistance, manufactured stone veneer is well-equipped to withstand Maryland’s humid summers, rainy springs, and occasional severe storms.

5. Timber
When choosing timber for garden walls in Maryland, it’s essential to weigh its affordability and natural charm against the maintenance it requires in the state’s ever-changing climate.
Durability
Timber’s durability can be a challenge in Maryland’s environment. The constant cycles of expansion, contraction, and exposure to moisture often lead to issues like cracks, mold, and decay. If wood stays wet with a surface moisture content above 20% for long periods, it becomes highly susceptible to mold growth [29].
To improve its longevity, it’s crucial to select pressure-treated or thermally modified wood and avoid any direct contact with soil. Without these precautions, timber is vulnerable to decay from repeated moisture exposure, temperature fluctuations, and freeze-thaw cycles.
Modern pressure-treated wood has come a long way. Jeanne Huber from The Washington Post highlights these advancements:
"It’s true that arsenic is no longer used as a preservative for wood sold for projects around the house, although it still can be used for some commercial projects. However, the replacement chemicals should ensure that wood lasts for decades, even when in contact with damp soil, which is where the fungi that cause wood to rot and insects such as termites and carpenter ants do the most damage." [26]
For better durability, consider thermally modified wood, which is heated to release moisture, improving its stability [28]. Proper installation is also key: structures should be at least 12 inches off the ground, with adequate spacing for water runoff. Creating an air gap of at least 1 inch behind boards helps prevent moisture damage [28].
Aesthetic Appeal
Despite its durability concerns, timber’s natural beauty makes it a standout choice for certain settings. Timber walls bring a warm, woodsy charm that fits perfectly in smaller or rustic landscapes [1]. They blend effortlessly into wooded areas and add unique character, enhancing Maryland’s natural surroundings. The organic look of wood creates an inviting atmosphere, complementing both classic and modern landscape designs.
Timber also offers versatility when it comes to design. Whether you prefer rustic split-rail styles or sleek, refined planks, wood allows for a wide range of aesthetic options. It’s also a renewable material, appealing to those who value environmentally-conscious choices [3].
Cost Range
Timber is one of the more budget-friendly materials for garden walls. Prices typically range from $10 to $40 per square foot, with pressure-treated options falling between $12 and $25 per square foot [1]. In Bethesda, Maryland, retaining wall costs vary from $16 to $50 per square foot depending on the material used, including timber [16].
While the initial cost is appealing, timber’s shorter lifespan compared to concrete or stone – both of which can last 40 years or more – may lead to higher replacement costs over time [30]. This makes it important to weigh the lower upfront investment against the potential for future maintenance and replacement expenses.
Suitability for Maryland’s Climate
Maryland’s climate, with its fluctuating weather and active insect presence, presents unique challenges for timber garden walls. Termites and carpenter ants are particularly problematic in this region [28]. However, with proper care and installation, timber can still perform well.
Key strategies for maintaining timber in Maryland include ensuring proper airflow behind boards, using corrosion-resistant fasteners like stainless steel, and maintaining good ventilation and drainage [28]. For added protection, lining timber structures with plastic can prevent direct soil contact [27]. Regular cleaning to remove dirt and organic buildup is another effective way to extend the lifespan of timber installations [28].
Though timber requires more upkeep than stone or concrete alternatives, it remains a practical and attractive option for Maryland homeowners seeking an affordable, natural-looking solution for their garden walls. By combining thoughtful installation techniques with regular maintenance, timber can thrive even in Maryland’s demanding climate.
