Why Retaining Walls Matter

If your property has slopes or elevation changes, retaining walls solve multiple problems. They prevent soil erosion, create usable flat areas, protect structures from sliding soil, and add visual appeal to your landscaping. Properly built retaining walls are engineered to handle the pressure of the soil behind them and last for decades.

Without proper retaining structures, sloped areas can wash away during rain, damage foundations, and make parts of your property unusable. Retaining walls turn problem slopes into functional terraced areas where you can build patios, plant gardens, or create more yard space.

Common Uses for Retaining Walls

  • Terracing sloped yards: Create multiple level areas for lawns, gardens, or seating areas.
  • Driveway support: Hold back soil along the sides of driveways on slopes.
  • Foundation protection: Prevent soil from sliding against basement walls or foundations.
  • Erosion control: Stop hillsides from washing away during storms.
  • Decorative landscaping: Add structure and visual interest to flat properties with raised planters or garden beds.

Types of Retaining Walls We Build

Different situations call for different retaining wall designs. We'll help you choose the right type for your property and budget.

Concrete Block Walls

Concrete masonry units (CMUs) are the most common and cost-effective option for retaining walls up to 4-6 feet tall. These interlocking blocks are strong, durable, and available in different colors and textures. They're installed on a compacted gravel base with proper drainage behind them.

Poured Concrete Walls

For taller walls or heavy-duty applications, poured concrete provides maximum strength. We build forms, install rebar reinforcement, and pour solid concrete walls that can handle significant soil pressure. These are often used for foundation support and large commercial projects.

Segmental Block Walls

Decorative segmental blocks create attractive walls with varied colors and textures. These work well for garden walls, planters, and decorative landscaping features. They're installed dry (without mortar) and rely on their weight and interlocking design for stability.

Mortared Stone or Brick Walls

For a traditional look, we build mortared walls using natural stone or brick. These require more labor but create a timeless appearance that complements historic or upscale properties.

What Makes a Retaining Wall Last

A retaining wall is only as good as what's behind it and under it. Poor drainage or inadequate base preparation causes even well-built walls to fail. Here's what we do to ensure your wall stays put.

Engineering and Design

For walls over 4 feet tall or walls supporting structures, we work with engineers to create proper designs. This ensures the wall has adequate thickness, reinforcement, and footing to handle the soil loads.

Foundation and Base

We excavate below grade and install a compacted gravel base. This provides a stable foundation that won't settle. For taller walls, we pour concrete footings to anchor the wall securely.

Drainage System

Water pressure behind a retaining wall can cause failure. We install drainage pipe behind the wall and use gravel backfill to allow water to drain away instead of building up pressure. This is one of the most critical steps that DIY builders often skip.

Reinforcement and Anchoring

Depending on wall height and soil conditions, we add rebar, geogrid reinforcement, or tiebacks to anchor the wall into the soil behind it. This prevents the wall from tipping or sliding forward over time.

Other Concrete Masonry Services

In addition to retaining walls, we handle other concrete masonry work for residential and commercial properties.

Outdoor Fireplaces and Fire Pits

We build custom masonry fireplaces and fire pits for your patio or backyard. These create gathering spaces and extend your outdoor living season.

Planters and Garden Walls

Low masonry walls define garden beds, create raised planters, and add structure to landscaping. We build walls that are both functional and attractive.

Steps and Transitions

When you have elevation changes, masonry steps provide safe, attractive transitions between levels. We integrate steps into retaining walls or build standalone stairways.
