Decorative & Structural Hardscapes Built to Last
A professionally designed retaining wall does more than hold back soil, it creates structure, improves drainage, and adds visual interest to your outdoor space. At Paragon Hardscapes, we specialize in retaining wall design and installation in Knoxville, TN and surrounding East Tennessee communities, creating durable hardscapes that blend structural performance with timeless design.
Whether your property needs erosion control, slope stabilization, or terraced outdoor living areas, our retaining wall systems are engineered to perform in Tennessee’s climate while enhancing the beauty of your landscape. Properly built retaining walls can transform steep or unusable yards into functional outdoor spaces such as patios, fire features, gardens, and entertaining areas.
Retaining Wall Design & Engineering
Proper retaining wall installation requires more than stacking blocks. Structural retaining walls must be engineered to manage soil pressure, water drainage, and long-term stability. Our process includes:
Professional Site Evaluation
We evaluate slope conditions, soil composition, and drainage patterns to determine the best retaining wall system for your property.
Custom Hardscape Design
For larger outdoor living projects, we create detailed conceptual designs that may include patios, driveways, lighting, and other integrated hardscape elements.
Engineering & Structural Planning
Retaining walls may require structural engineering to ensure they perform correctly over time—especially for taller walls or complex hillside installations.
Typical Retaining Wall Estimates
Because of the need for additional site preparation prior to installation, typical costs for retaining walls are between $50 and $75 per sq. ft. (including height and depth). Typical project ranges are shown below for your consideration.

What is the difference between a decorative and structural retaining wall?
A decorative wall is primarily aesthetic and handles minimal soil pressure. A structural retaining wall is engineered to hold back significant amounts of soil and must account for drainage, soil pressure, and long-term stability.

What causes retaining walls to fail?
The most common causes are poor drainage, inadequate base preparation, and walls that were not engineered for the soil load behind them. All three are addressed in every Paragon Hardscapes installation.

Can a retaining wall create usable space in my yard?
Yes. Terracing a sloped yard with retaining walls is one of the most effective ways to create flat, functional outdoor space for patios, kitchens, fire features, and gardens.
