DIY Retaining Wall Installation Tips for Greensboro Homeowners

Embarking on a DIY retaining wall project can be a rewarding challenge. With the right preparation and materials, creating a functional and aesthetically pleasing retaining wall is achievable for ambitious homeowners. Southern Outdoor Living is here to guide you through the process, ensuring your project in Greensboro, NC, is a success.

Step 1: Preparation and Planning

Preparation cannot be overstressed. A well-prepared base is crucial to prevent potential wall failure. For walls over 4 feet, consult with a professional engineer and check local building codes, as they may require professional designs and geogrid reinforcement.

Step 2: Material Selection

Choose durable, easy-to-install materials like Versa-Lok wall blocks and pins. After determining the size and layout, calculate the number of blocks needed and gather your materials.

Step 3: Site Preparation

Excavate the site to a depth that allows for a base and positions the first block layer slightly below ground level. Aim for a base depth that’s about 1/10 of the wall’s height. Lay down a 6-inch layer of compacted gravel or crushed stone, topped with a thin layer of sand for a level base.

Step 4: Laying the First Course

Place the first layer of blocks on the sand, ensuring each is level in all directions. Start at a corner or use a string line for straight sections to maintain alignment.

Step 5: Backfilling and Drainage

Backfill the area in front and behind the first block layer with soil, compacting it to grade level. Add a 12-inch layer of drainage material behind the wall, ensuring it’s well-compacted.

Step 6: Building Up

Continue stacking blocks, setting each layer back by ¾ inch using two pins per block for alignment and stability. Add drainage material and compact after each layer.

Step 7: Cap Installation

Finish the wall with cap blocks for a polished look, using adhesive to secure them in place. Adjust the overhang to your preference.
