Similarly one may ask, how do you dry stack flagstone walls?

Stagger the stones like brickwork to make the wall more stable. Keep the straight edge of the rocks at the front of the wall, unless you want a rustic, natural look. Use a stone hammer to shape any pieces that need some help. Place pretty, large, flat rocks on top of the all as capstones.

One may also ask, do I need a footer for a retaining wall? A concrete footing serves as the foundation of many construction projects. If you plan to use brick, cinder block or stone that will include the use of mortar, then a concrete footing is recommended. If you are building a segmental retaining wall, then you will not need a footing.

Secondly, do you need landscape fabric behind retaining wall?

Whether the wall is made from stones, bricks or wood, it is important to provide a barrier between the building blocks and the soil. Landscape fabric is thin and sturdy and is a simple way to preserve a retaining wall's construction.

Should you glue retaining wall blocks?

Seasonal movement can be substantial. At 6 blocks tall, I would not recommend masonry adhesive. Adhesive is fine for caps or just a couple of courses, but six interlocking courses should have mortar and possibly vertical re-bar if you want it to last more than a season or two.
