Building A Retaining Wall

As Bayside Pavers (https://baysidepavers.com), we’re excited to guide you through the process of building your own retaining wall system. A DIY retaining wall project can transform your outdoor space, adding both functionality and beauty to your property. This comprehensive guide will educate you on what retaining walls are, their benefits, and the detailed steps to construct one yourself, ensuring a professional outcome that enhances your landscape.

What Are Retaining Wall Systems?

Retaining walls are sturdy structures designed to hold soil in place and prevent erosion, particularly on properties with slopes, hills, or uneven terrain. These systems are essential for stabilizing landscapes, managing water runoff, and creating usable outdoor spaces. By installing a retaining wall, you can protect your yard from soil displacement, reduce the risk of structural damage, and enhance the overall aesthetic of your property. Retaining walls can vary in height, from a few feet for small garden beds to taller structures at the base of steep inclines, providing both safety and visual appeal.

Benefits of Installing a Retaining Wall

Building a retaining wall offers numerous advantages beyond erosion control:

  • Property Protection: Retaining walls stabilize soil, preventing landslides or erosion that could damage your lawn, plants, or home foundation.
  • Increased Property Value: A well-designed retaining wall is considered a valuable investment by realtors and appraisers, potentially boosting your home’s market value or supporting a home equity loan.
  • Enhanced Aesthetics: Retaining walls can be customized to complement your landscape, creating defined spaces like garden beds, seating areas, or pathways.
  • Functional Spaces: Use retaining walls to level sloped areas, making them ideal for patios, walkways, or pool surrounds, or to add privacy to your yard.
  • Water Management: By slowing rainwater runoff, retaining walls help prevent flooding and soil erosion, preserving your landscape design.

Planning Your DIY Retaining Wall

Before starting your project, careful planning is crucial to ensure a safe and durable retaining wall. Follow these steps to prepare:

1. Assess Your Property

Evaluate your yard to determine where a retaining wall is needed. Look for areas with slopes, hills, or erosion issues. Consider the wall’s purpose—whether it’s to level a space for a garden, create a pathway, or secure a steep incline. Measure the area to estimate the wall’s height and length, keeping in mind that walls over 4 feet tall typically require professional engineering for safety.

2. Check Local Regulations

Contact your local building authority to verify zoning laws, permits, or restrictions for retaining walls. Some areas require permits for walls above a certain height (often 3–4 feet) or near property lines. You may also need to check for underground utilities by calling 811 before digging.

3. Choose the Right Materials

Select materials that match your aesthetic preferences and functional needs. Common options include:

  • Concrete Blocks: Durable, versatile, and available in various shapes, textures, and colors. Ideal for straight or curved walls.
  • Natural Stone: Offers a timeless, organic look but may be harder to stack uniformly.
  • Brick: Provides a classic appearance, best for smaller, decorative walls.
  • Timber: Cost-effective but less durable, suitable for low walls in less demanding environments.Consider the wall’s shape—curved walls require flexible blocks, while straight walls need tightly fitting materials. At Bayside Pavers, we offer a wide range of high-quality paver blocks designed for easy installation and lasting performance.
4. Gather Tools and Materials

You’ll need the following for your DIY project:

  • Tools: Shovel, level, tamper, mason’s string, stakes, tape measure, rubber mallet, wheelbarrow, safety gear (gloves, goggles).
  • Materials: Retaining wall blocks, gravel, sand, landscape fabric, drainage pipe, adhesive (for taller walls), backfill material.
  • Optional: Geogrid reinforcement for walls over 3 feet tall.

Step-by-Step Guide to Building a Retaining Wall

Follow these detailed steps to construct a sturdy and attractive retaining wall:Step 1: Mark and Excavate the Area

  • Use stakes and mason’s string to outline the wall’s path, ensuring it’s straight or smoothly curved as desired.
  • Dig a trench along the marked line, about 6–8 inches deep and twice the width of your blocks (typically 12–16 inches). The trench should be level to provide a stable foundation.
  • Remove any grass, roots, or debris from the trench.
Step 2: Create a Solid Base
  • Fill the trench with 4–6 inches of crushed gravel or base material. Spread it evenly and use a tamper to compact it firmly. A solid base prevents settling and ensures long-term stability.
  • Check the base with a level, adjusting as needed to ensure it’s flat and even.
Step 3: Lay the First Course
  • Place the first row of retaining wall blocks in the trench, ensuring they’re level side-to-side and front-to-back. Use a rubber mallet to tap blocks into place.
  • For curved walls, select blocks designed for flexibility, and follow the manufacturer’s guidelines for alignment.
  • If your blocks have a lip or interlocking system (common in Bayside Pavers’ products), ensure they lock securely with the base material.
Step 4: Install Drainage
  • Behind the first course, lay a perforated drainage pipe along the length of the wall, sloping slightly to direct water away from the structure.
  • Cover the pipe with a layer of gravel (about 6 inches) to promote drainage and prevent soil clogging.
  • Place landscape fabric over the gravel to keep soil from mixing with the drainage material.
Step 5: Build Additional Courses
  • Stack the next row of blocks, staggering the joints (like a brick pattern) for stability. Ensure each block is level and secure.
  • For taller walls, apply construction adhesive between courses to enhance strength, following the adhesive manufacturer’s instructions.
  • If building a wall over 3 feet, incorporate geogrid reinforcement every 2–3 courses. Lay the geogrid fabric over the blocks, extend it back into the soil, and cover with backfill before adding the next course.
Step 6: Backfill and Compact
  • Fill the space behind the wall with gravel or soil, compacting it in 6-inch layers to prevent settling. Ensure the drainage pipe remains functional.
  • For aesthetic walls, add topsoil for planting or mulch for a finished look.
Step 7: Finish the Wall
  • Cap the wall with finishing blocks or capstones for a polished appearance. Secure capstones with adhesive.
  • Inspect the wall for levelness and stability, making adjustments as needed.
  • Clean the blocks with a brush to remove dirt or debris.
Maintenance Tips for Your Retaining Wall

To keep your retaining wall looking great and functioning properly:

  • Regularly check for signs of erosion or shifting, especially after heavy rain.
  • Clear debris from the drainage system to prevent clogs.
  • Inspect for cracks or loose blocks, repairing them promptly with adhesive or replacement blocks.
  • If plants are incorporated, maintain them to avoid root damage to the wall.

  1. Trench: Dig a 6-inch-wide, 12-inch-deep trench alongside the retaining wall, sloping slightly (1% grade) toward the street.
  2. Line with Fabric: Place landscape fabric in the trench to prevent soil clogging the drain.
  3. Add Gravel: Spread 2 inches of drainage gravel in the trench bottom.
  4. Install Pipe: Lay a 4-inch perforated PVC pipe, ensuring perforations face downward. Connect to a solid PVC pipe at the street end for discharge.
  5. Cover and Backfill: Surround the pipe with gravel, wrap the fabric over the top, and backfill with soil or gravel to integrate with the retaining wall.

Goal Note: The French drain ensures water is efficiently channeled away from the house, preventing pooling near the foundation.

6. Installing the Car-Grade Drain

A car-grade channel drain at the garage door prevents water from entering the garage.

  1. Trench: Excavate a narrow trench (4–6 inches wide) across the driveway where it meets the garage door, ensuring a slight slope toward the street or French drain.
  2. Install Drain: Place a heavy-duty channel drain (rated for vehicle traffic) in the trench, leveling it with the surrounding surface. Connect to the French drain or a separate drainage pipe leading to the street.
  3. Secure: Backfill with concrete or gravel around the drain to lock it in place, ensuring it’s flush with the future paver surface.
7. Laying the Bedding Sand
  1. Spread 1 inch of concrete sand over the compacted subbase.
  2. Screed the sand using a straight board to create a smooth, even surface.
  3. Check the slope again to ensure water will flow toward the street.
8. Installing Belgard Avalon Slate Bella Pavers
  1. Start Laying Pavers: Begin at the garage door or a fixed edge, laying Avalon Slate Bella pavers in your chosen pattern (e.g., herringbone or running bond for strength). Ensure tight joints (1/8 inch or less).
  2. Cut Pavers: Use a masonry saw to cut pavers for edges or around the car-grade drain.
  3. Check Alignment: Use a string line to keep rows straight and a level to ensure flatness.
9. Adding the Belgard Graphite Border
  1. Place Border Pavers: Install Graphite pavers along the driveway’s perimeter, adjacent to the retaining wall and other edges. Cut as needed for a precise fit.
  2. Secure: Use concrete adhesive for border pavers along the retaining wall to prevent movement.
10. Compacting and Finishing
  1. Compact Pavers: Run a plate compactor over the pavers to set them into the sand.
  2. Add Joint Sand: Sweep polymeric joint sand into the gaps between pavers. Mist lightly with water to activate the sand’s binding properties.

From start to finish, my experience with Bayside Pavers was excellent. They provided a clear estimate, worked within my budget, and delivered on time. The new walkway looks fantastic and has added so much value to my home.

I recently had my driveway paved by Bayside Pavers, and I couldn't be happier with the results. The team was professional, efficient, and the quality of work was outstanding. I highly recommend them to anyone looking for paving services.
