Materials
- 42 retaining wall blocks (16 x 6 x 8 inches)
- 4 bags of pea gravel or river pebbles (40 lbs each)
- 1 steel fire ring (36 inches diameter)
- 3 bags of sand or base gravel (50 lbs each)
- Shovel, level, and tamping tool
Instructions
- Mark a 5-foot-wide circle in your yard and dig 4 inches deep to remove grass and roots.
- Add a layer of sand or base gravel to the bottom, about 2 inches thick, and tamp it level for stability.
- Place the first ring of blocks in a tight circle, ensuring they sit evenly. This will form your foundation.
- Add a second ring of blocks on top, staggering the seams for better strength.
- Create the outer decorative ring by placing a wider circle of blocks around the fire pit, leaving a small gap in between for drainage and aesthetics.
- Fill the space between the two rings with pea gravel or river stones to prevent weeds and create a polished finish.
Notes
Use heat-resistant adhesive between the block layers for extra durability. The pebbled ring not only looks beautiful but also protects your lawn from heat and sparks.
