TOP 5 Things to Consider When Building a Retaining Wall

Retaining walls are more than just functional—they're foundational. Whether you're tackling a sloped yard, preventing erosion, or adding aesthetic structure to your landscape, a retaining wall must be built with careful planning and the right materials. Poorly constructed walls can shift, crack, or even collapse over time, leading to costly repairs and safety hazards.

Here are five essential things to consider before building a retaining wall on your property:

🧱 1. Purpose and Function

Before anything else, determine the main purpose of your retaining wall. Are you:

  • Holding back soil on a slope?

  • Preventing erosion or managing runoff?

  • Creating level areas for planting or patios?

  • Adding visual interest or defining space?

Understanding the wall's function will help determine its height, material, drainage needs, and whether you’ll require professional engineering.

💧 2. Soil Conditions and Drainage

Water and soil pressure are the biggest threats to retaining walls. If the drainage system isn’t properly designed, water buildup behind the wall can lead to failure. Every well-built wall should include:

  • Gravel backfill

  • Drain pipes or weep holes

  • Filter fabric to prevent soil clogging

Also consider your soil type—clay soils retain water and need extra drainage support, while sandy soils drain quickly but may require stabilization.

📏 3. Wall Height and Permits

In many areas—including San Diego County—retaining walls over 3 to 4 feet high may require permits and engineering plans. Taller walls often need:

  • Geogrid reinforcement

  • Engineered drawings

  • Deeper foundations or stepped designs

Always check with your local municipality before starting construction.

🧩 4. Material Selection

Choosing the right material is both a structural and aesthetic decision. Popular options include:

  • CMU block – Great for structural and plastered finishes

  • Segmental retaining wall blocks (SRWs) – Interlocking and stackable

  • Natural stone – Adds organic beauty, best for short walls or facades

  • Poured concrete – Clean, modern, and strong

The material should complement your home’s design, landscape style, and long-term durability needs.

👷‍♂️ 5. Professional Installation

Retaining walls are not basic DIY projects—especially when soil retention or height is involved. Hiring a licensed, experienced contractor ensures your wall:

  • Meets code

  • Has proper drainage and reinforcement

  • Lasts for decades
