Types of Retaining Walls We Build

Stone, block, or concrete: which retaining wall is right for your property? The answer depends on the wall height you need, your soil stability, drainage challenges, and the look you want to achieve. Our team evaluates these factors to recommend the materials that deliver structural integrity and the right look.

Stone Retaining Walls (Rockery)

Natural stone retaining walls, also called rockery walls, use basalt, granite, river rock, and other Pacific Northwest stone to create stunning walls that blend with the landscape. Stone retaining walls offer unmatched durability (50-100+ years), superior drainage, and a natural, premium appearance.

Concrete Block Retaining Walls

Concrete block retaining walls provide excellent structural support at a cost-effective price point. Modern concrete blocks come in a selection of colors, textures, and styles, allowing for attractive retaining wall landscaping designs. Block retaining walls are suitable for taller walls and heavy-duty applications.

Poured Concrete Retaining Walls

Poured concrete retaining walls offer maximum strength and versatility. These solid concrete retaining walls can be shaped to fit any space and are often the best choice for commercial properties or areas requiring significant structural support. We can finish concrete walls with textures and color to complement your landscape design.

Retaining Wall Drainage Solutions

Retaining walls fail without proper drainage, especially in Seattle’s wet climate. We integrate French drains, weep holes, and gravel backfill, as needed, into retaining wall installations to prevent water buildup behind your wall. Whether you choose stone, block, or concrete retaining walls, our drainage systems protect your investment by directing water away from the structure. The result is a wall that stands strong for decades without bowing, cracking, or settling from hydrostatic pressure.

Retaining Wall FAQs

Do I need a permit for a retaining wall in Seattle?

In Seattle, retaining walls over 4 feet in height typically require a building permit and engineered plans. Walls in critical areas, near property lines, or supporting structures may have additional requirements. As experienced retaining wall contractors, we can help navigate the permit process.

What’s the difference between a rockery wall and a block retaining wall?

Rockery (stone) retaining walls use natural stone for a timeless, organic appearance and exceptional durability. Block retaining walls use manufactured concrete blocks that offer consistent sizing, faster installation, and lower costs. Stone walls typically last 50-100+ years, while quality block walls last 30-50 years.

How long does retaining wall installation take?

Most residential retaining wall projects take 1-4 weeks, depending on wall height, length, site access, and complexity. Small garden retaining walls may be completed in 3-5 days, while large terraced systems can take several weeks. We provide detailed timelines during the design consultation.

What type of retaining wall is best for my property?

The best retaining wall depends on: wall height needed, soil conditions, drainage requirements, budget, and aesthetic goals. Stone retaining walls excel for natural beauty and longevity. Concrete block retaining walls offer versatility and cost-effectiveness. Poured concrete retaining walls provide maximum strength for challenging sites. We will assess your property and recommend the optimal solution.

Can you repair or replace an existing failing retaining wall?

Yes! We provide retaining wall repair and replacement services. Signs you need repair include leaning, cracking, bulging, drainage issues, or separation from soil. Our team assesses the damage and recommends whether repair or full replacement is the most cost-effective solution.

Do retaining walls need maintenance?

Well-constructed retaining walls require minimal maintenance. We recommend annual inspections for drainage function, checking for settling or movement, and ensuring proper water flow. Stone retaining walls may develop beneficial moss and patina over time. Periodic cleaning and minor repairs extend the life of any retaining wall system.

Will a retaining wall increase my property value?

Yes! Professional retaining wall installation typically increases property value by creating usable space, improving drainage and erosion control, and enhancing curb appeal. Stone retaining walls, in particular, can increase property value when well-designed and properly installed.
