Durable, beautiful retaining walls in Seattle — built to stand the test of time.
Retaining Walls
In Seattle’s hilly terrain, retaining walls are a common and essential landscape feature. Whether you're looking to level out a steep slope, add usable yard space, or simply enhance the character of your landscape, a well-designed retaining wall can make a big impact.
Retaining walls not only improve the function and appearance of your yard, they also help stabilize soil, manage drainage, and add long-term value to your property.
Types of Retaining Walls We Build
At Ecoyards, we install a variety of retaining walls using different materials and techniques—each suited for specific site conditions, aesthetics, and budgets.
Interlocking Block Retaining Walls
Also known as segmental retaining walls, these systems use specially engineered concrete blocks that stack without mortar. Ideal for walls up to four feet tall, block systems are both strong and attractive.
Benefits:
- Mortar-free, easy to repair or expand
- Wide range of colors and textures (gray, reddish, rustic, etc.)
- Style options: smooth modern face, curved traditional face, or rustic tumbled blocks
- Built on a compacted gravel base with integrated drainage
Segmental blocks are a popular choice for their clean look, strength, and ease of installation on residential properties.
Boulder and Dry-Stack Stone Walls
Natural stone walls bring a rugged, organic look to your landscape and blend beautifully with Pacific Northwest surroundings.
Boulder Walls
- Made from basalt, granite, or other large stones
- Typically built under 4 feet tall
- Can be mortared or dry-stacked, depending on style and function
- Great for naturalistic, informal designs
Dry-Stack Walls
- Built using flat stones like ledgestone, flagstone, or fieldstone
- Mortar-free, allowing natural flexibility with soil movement
- Earthquake-resistant and easy to repair
- Timeless, low-maintenance, and full of character
Wood Retaining Walls
Wood is a cost-effective and practical solution for many properties—especially in areas where equipment access is limited.
Details:
- Built using pressure-treated or juniper 6×6 timbers.
- Reinforced with “deadmen” anchors for added stability
- Suitable for terracing or smaller retaining needs
- Expected lifespan: 20+ years with proper materials
Wood walls are ideal for homeowners seeking a clean, natural look and quicker installation time.
