Fieldstone/Boulder Retaining Wall
Pros of Fieldstone/Boulder
Cons of Boulders
Because boulders are generally quite big, you will need a larger yard space to build a boulder retaining wall. You also will not be able to build these walls too high.
The first thing you’ll need to do is determine where you want to place your wall. Using wooden stakes, place them every 8 feet to reach the desired length, and tie a string around each one and connecting them at the height you want. Make sure to use a line level to ensure the string is level. Next use a shovel or excavator to carve out the dirt wall the boulders will lay against. Make sure the wall slants inwards gradually.
Next you’ll want to place landscape fabric along the dirt wall and on the ground where you are laying your boulders.
Now start laying down the second layer, being sure that the boulders you use fit the contour of the row below, and that they are touching the back of the wall. If you’re wanting to add some variation to the look of your wall, you can turn rocks sideways and lay them down vertically. They may take up 2 rows but if done properly they can look really good. Each row after this can be done in the same way.
Now that you’ve done all the layers you can fill all the big gaps with smaller rocks. If you’re looking to add some landscape rock at the top then lay down the landscape fabric before hand. If not, then you’ll want to cut the fabric where the wall ends and seal the edges of the fabric with flame.
