Step 1

Dig a Trench
Dig a trench about 12" deep to create a level surface before laying any stone.
Step 2

Lay the Stone
Install a layer of large stones for good stability at the base. No mortar is needed. Stagger the joints as you lay the next level. The top of the wall should be at finished grade to allow runoff.
Step 3
Finish With Crushed Stone
Fill behind the wall with crushed stone.
Note: If you're building a wall higher than 3' tall, be sure to check with your local community to find out if a permit is required.
