Regularly check the alignment and level of your DIY stone retaining wall as you build. Use a level and string line to ensure the wall remains straight and true. Correct any deviations promptly to maintain the wall’s structural integrity.
Adding Geotextile Fabric
Purpose of Geotextile Fabric
Geotextile fabric plays a crucial role in preventing soil erosion and maintaining the wall’s stability. It acts as a barrier between the soil and the stones, allowing water to pass through while keeping the soil in place. This fabric enhances the wall’s durability and longevity.
Installing the Fabric
Install the geotextile fabric behind the retaining wall as you build. Lay the fabric along the wall’s backside, ensuring it extends the entire height of the wall. Secure the fabric with pins or staples to keep it in place during construction.
Layering the Wall
Integrate the geotextile fabric with the stone layers as you build the wall. Ensure each layer of stones is supported by the fabric, enhancing stability and preventing soil movement. Proper layering ensures a seamless and secure installation.
Finishing Touches
Capping the Wall
Capping the wall adds a polished look and provides a protective top layer. Choose capstones that complement the wall’s design and securely place them on the top course. Use mortar to fix the capstones in place, ensuring they are level and aligned.
Backfilling and Tamping
After capping the wall, complete the backfilling process. Add soil behind the wall, layering it with gravel for proper drainage. Compact the soil and gravel to eliminate air pockets and enhance stability. Proper backfilling ensures the wall’s durability.
Inspecting and Adjusting
Perform a final inspection of your DIY stone retaining wall to ensure it meets all standards. Check for alignment, stability, and any potential issues. Make necessary adjustments to ensure the wall is secure and aesthetically pleasing.
