WHAT IS A RETAINING WALL?
Retaining walls are sturdy structures built to hold back or retain soil, rock, or other materials to account for differences in ground elevation. These walls typically exceed 2 feet in height and require advanced engineering to withstand the pressure from retained materials, unlike traditional garden walls. Common applications for retaining walls include terraced slopes, leveling uneven terrain, and creating a stable base for raised patios or pool decks. Unilock retaining wall blocks are manufactured to exceed the industry standards set by ASTM, CSA, and other European organizations, ensuring long-lasting durability and exceptional visual appeal. With a wide range of colors, shapes, sizes, and textures to choose from, you can design a retaining wall that will elevate your home’s beauty to new heights.
IMPORTANCE OF ENGINEERING A RETAINING WALL FOR STRUCTURAL SUPPORT
If you’re designing a structural retaining wall that is going to exceed 2 feet in height, you must have a qualified civil engineer review the design before you get started. Skipping this step could open the door to potential structural design issues later on, like bulging, cracking, or leaning—and in the worst case, a total collapse. A well-engineered retaining wall takes into account three key factors: structural support, drainage, and erosion control. Proper drainage, including a free-draining gravel base, gravel backfill, and drainage pipe, helps reduce the buildup of water pressure behind the wall. Additionally, erosion control measures like compacted soil or geogrids stabilize the ground, preventing washouts that could weaken the structure.
HOW RETAINING WALLS INCREASE THE USEABLE SPACE ON YOUR PROPERTY
Unilock retaining wall blocks can significantly enhance the usability of your property by transforming uneven or sloped terrain into functional, level areas. They are ideal for creating terraces on steep land, which can serve as decorative garden beds, play areas, or outdoor dining areas. Retaining walls can also help delineate distinct “rooms” for gathering, lounging, or seating. For example, low walls can double as built-in seating around patios or fire pits, blending function with style. Whether your goal is to support elevated features like raised patios, or simply add visual interest, Unilock retaining walls offer endless design opportunities to maximize every inch of your outdoor space.
DESIGN CONSIDERATIONS FOR RETAINING WALLS USING U-CARA
The U-Cara® Multi-Face Wall System allows you to mix and match fascia panels to create a custom look for your retaining wall. The system consists of “backer blocks”, which are molded with horizontal rails, allowing you to mount the fascia panels directly on the wall. This design offers endless possibilities for colors, textures, and patterns, making it easy to achieve the perfect style. For added visual interest, consider incorporating accent banding into your U-Cara retaining wall. Using a complementary color or texture that echoes your patio’s borders, driveway, or even elements from your home’s architecture, can help tie your entire design together.
WHY UNILOCK RETAINING WALL BLOCKS ARE THE SUPERIOR CHOICE FOR DURABILITY AND EASE OF INSTALLATION
Premium Unilock retaining wall blocks are engineered for both exceptional durability and ease of installation. With a minimum compressive strength of 5000 PSI, these blocks provide consistent unit weight, impressive shear strength, and superior resistance to freeze/thaw cycles, ensuring lasting performance even in the harshest conditions. Unlike many wall blocks that feature internal voids or cavities that would require core filling, Unilock wall blocks are solid, eliminating the need for additional materials, clips, or pins. This reduces labor time and simplifies installation for your contractor. Plus, the integral tongue-and-groove system makes stacking blocks quick and precise, allowing contractors to build retaining walls and other hardscape features efficiently, without compromising on design or structural integrity.
