Building Mountain Boulder Retaining Walls

What to do when neighbor’s weeds are infringing on your property.

Build a mountain boulder wall. It prevents them from skipping over that hard surface. No, really. It’s about the soil and holding the mountain in place. Some use RR ties or timbers to build retaining walls and that’s ok too.  There’s always a place and time for big mountain boulders. Boulder walls can take a ton of pressure since they’re found in the mountainous region of Western North Carolina and are plentiful.

Creating a Firm Foundation for Mountain Boulder Retaining Walls

In building a mountain boulder wall, the slope and grade have to be considered and the maneuverability to get the machinery into the space to lay the boulders and stack. If mountain boulder walls are an option for the area, grading may be preliminary to the job as well as cleaning the surface of the terrain. Our forestry mulching equipment along with excavators and a skid loader can carve out and grade and clear the specific area. Footers for the mountain boulder walls are dug. The mountain boulders are divided out between the small, medium and large. The bank is blanketed with a heavy landscape fabric to prevent erosion and sediment from running off. The wall is then carefully constructed using a fine assortment of harvested creek stone with moss and lichen laden boulders of a mixed size and variety. The wall is started by choosing the larger, flatter stone to establish the first base course. The jagged and imperfect side is left face down to act as an anchor in the soil. The second course is ready and the flat layer is positioned upward continuing with each course.

Mountain boulders are moved with the CAT skid loader and a mini excavator with a thumb that carefully handles each stone in stacking. Attention is given to not scratch and scar the mountain boulders or knock the moss and lichen off. This preserves the aesthetic look of the stone and its embellishment to appear as though it’s always been in place. As the boulders are stacked, the stones are placed like a jigsaw puzzle pieces and layered tightly so the joints are minimal. As the wall goes up, graduated sizes of mountain boulders and rock are placed strategically. Once the wall is completed, the gaps are filled in with smaller boulders and rock. As the layers are being placed, stone and soil backfill is being packed behind the boulders. Finally, a level top course is set and the finishing touches to the rest of the area are performed such as plantings or mulch and edging.

If you’re perched on a hillside and getting too much soil running over to your side of the mountain, it might be time for a mountain boulder retaining wall. Give us a call and we can give you the details.
