Retaining walls are a fantastic way to manage sloped landscapes, prevent soil erosion, and add attractive structural elements to your yard. If you’re considering building one, use high-quality retaining wall blocks from Southwest Stone Supply in Columbia, Missouri, and Osage Beach to ensure a sturdy and long-lasting result. Follow this step-by-step guide to build a retaining wall that will stand the test of time.

Step 1: Plan Your Retaining Wall

Proper planning is crucial. Consider the following:

  • Wall Height: Walls over 4 feet may require professional installation.
  • Location: Identify the best spot while considering drainage and soil type.
  • Materials: Southwest Stone Supply offers various retaining wall blocks for sale to match your landscape design.

Pro Tip: Check with local authorities for any required permits before starting.

Step 2: Prepare the Site

  1. Mark the Layout: Use stakes and string to outline the wall.
  2. Excavate the Base: Dig a trench about 6-8 inches deep and twice the width of the blocks.
  3. Level the Base: Fill the trench with 4-6 inches of crushed stone and compact it with a hand tamper.

Key Insight: A solid, level base ensures the wall’s stability and longevity.

Step 3: Lay the First Course

  • Position the first row of blocks directly on the compacted base.
  • Ensure each block is level from side to side and front to back.
  • Use a rubber mallet to make slight adjustments.

Tip: Take your time with this step; any mistakes here will affect the entire wall.

Step 4: Build and Backfill

  1. Stagger the Joints: Stack subsequent rows in a staggered pattern for strength.
  2. Backfill: After each course, backfill with gravel behind the wall for drainage.
  3. Compact: Use a hand tamper to compact the gravel.

Drainage Matters: Proper drainage prevents water pressure buildup, which can cause wall failure. This is of paramount importance!

Step 5: Cap and Finish

Design Tip: Southwest Stone Supply offers capstone options that enhance your wall’s aesthetic appeal.
