To have all the sizes needed for dry stone wall construction often multiple grades or sizes will need to be purchased.
How do you calculate the width of a stone wall?
Determine the length of the stone wall in feet. Calculate the wall width. Rock wall width should always be 2/3 of the wall height. Use this formula to calculate the wall width: Y = 2/3X; where X = wall height, Y = wall width; For example, if a rock wall is 3 feet high, the width should be 3 x 2/3 (or .666) = 2 feet.

Why are stones not level?
Stones that are not level will tend to slide causing internal stress in the wall and will eventually cause failure as the wall shifts over time. Many walls are built with quite irregular shaped stone, when this is the case focus on keeping the top of the stones level. That makes it easier to build on top of.
What is dry stone construction?
Dry stone construction is a separate construction technique and profession from masonry. While there is overlap with masonry and other building trades, dry stone wallers have their own vocabulary and terminology. Understanding this terminology will help you when reading the rest of this page.
How do I build a field wall?
Building a new wall begins by preparing a foundation . When building a field wall, remove any topsoil, roots and organic matter from the where the wall will be built, and firmly compact the subsoil. Typically 4-6 inches below ground level is sufficient. Just like for rebuilding, clear space is needed along the wall. There should be sufficient access to have the stone delivered right next to where the wall will be built. If not, you will need to figure out a way to get it there. When stone is delivered in a dump truck it leaves a big pile, sizes are all mixed up, and hearting, if there is any, is at the bottom. It is worth every bit of your time to sort through the pile before you begin building. I find the most efficient method is start on one side of the pile and sort it into rows according to thickness, not overall size. As the pile gets sorted the rows get longer. I set this up so that the rows are parallel to the wall, with the thickest stones closest to the wall.

When a dry stonewall does finally fail, it can be rebuilt using the same stone. Dry stonewalls are usually built ...
How is a dry stone wall held up?
A dry stonewall is fundamentally held up by friction and gravity. The friction between the stones keeps them from sliding apart and the weight of the stones increases the friction. When building a wall, the aim is always to maximize the friction and use gravity to the best advantage. .

How wide should a wall be?
For stability, walls should be at least 20 inches wide at the base. They can taper slightly toward the top, but you’ll want a wall that is at least two rocks wide in most places. This can be accomplished by mixing stones of different sizes or by backfilling with a combination of two-thirds rubble to one-third soil.
How do I build a stone wall?
Start by digging a trench about 4 inches deep and at least 2 feet wide. A straightedged spade will give you a nice, even edge. The first course must be very solid and tightly fit because the weight of the wall will rest on it. Take the time to find rocks that lock into place, without leaving gaps. Randomly lay your largest rocks along the front edge of the trench. Set the first stone, shifting it around until it sits securely without being rocked easily, and then fill with the remaining stones. If you are using rectangular stones, you want the height of adjacent stones to be the same, or of a difference that can be made up with a smaller stone. If the rocks are irregular, then the stones will fit together leaving a triangular gap for the next course to fit into. I find irregular rocks easier to work with than flat ones; with flat rocks you have to be more precise. Find a stone that fits well and then continue for a few more feet. A rule of thumb, passed down from my wall-building teacher’s mentor, is to try a stone seven different ways. If it doesn’t fit by the seventh try, use another stone.
What happens when you use rectangular stones?
If you are using rectangular stones, you want the height of adjacent stones to be the same, or of a difference that can be made up with a smaller stone. If the rocks are irregular, then the stones will fit together leaving a triangular gap for the next course to fit into.
How deep should a capstone be?
It should be about 15 to 18 inches deep, made up of one to three stones. Use soil and good placement to secure the stones, and just as with wall joints, avoid lengthy joints in the capstone. If you want to sit on the wall, choose smooth, flat stones. Or, fill gaps with soil and plant fragrant herbs for cushions.
Why do you put rubble on a wall?
This is an important step because the dirt becomes the mortar for the wall. I also recommend adding rubble (those stones you won’t use on the face of your wall) behind the face course to give greater strength to the wall. Pound the rubble and soil mix until you are satisfied that it is solid.
How high should a dry stacked retaining wall be?
The ideal height for a dry-stacked retaining wall is 18 to 22 inches —so you can sit on it when your gardening chores are done. Even if you don’t plan to sit on your wall, 3 feet is about as high as I would recommend building any dry-stacked wall; higher walls should be engineered for stability.
What happens when you cut and fill a wall?
When you cut and fill, the wall is backed by undisturbed soil, which is more stable than fill. For design reasons, however, you might choose to build a freestanding wall and fill behind it with soil from another site. Or you might do a partial cut and fill, which is somewhere between the two. Walls are built in courses.
What are the different types of stone walls?
Types of Stone Walls 1 Tossed walls are those rambling paddock walls that often make us think of Ireland. Farmers just tossed rocks into fence rows as they worked the fields, building a wall up. 2 Laid walls are more orderly than tossed walls. The stone is placed and secured (without mortar) to make a well-fitted wall. These are the walls throughout the south that are often referred to as “slave walls.” These are also referred to as dried stacked walls. 3 Curved flagstone walls are a popular way to define a patio or backyard kitchen. They also make dynamic looking stone raised beds. 4 Mortared stone walls are ideal as retaining walls because they’re strong enough to hold back the earth. 5 Stacked block walls are made of mortared concrete blocks. They are more formal and create a courtyard effect.

How to give a wall strength?
To give the wall strength, you need to stagger the joints between courses. So the second row of the wall should start with a half stone to offset the alignment of the joints. Using a mason's chisel, mark and score every side of the stone at the point where it will be cut.
How to compact paver base?
Using a hand tamper, compact the base. Measure the distance from the base to the level line to make sure the base stays level. If necessary, pour additional layers of paver base and tamp each one until the surface of the base at the low point of the slope is half the depth of one block, plus 1 inch, from ground level.
How to level a wall?
A level and sturdy wall all depends on the positioning of the first course. A first course that tilts will tilt the block stacked on top of it, and one with gaps will throw off the rest of the joints. If there's any slope to your area, begin to set the stones from the high end of your trench and build up the low areas to avoid having to remove any stone dust.

Why use a cap stone?
Use Cap Stones. Cap stones are necessary for 2 reasons: 1. They help hold the top of the wall together, and. 2. They keep out moisture and eliminate frost damage. 8. Choose the correct face on the stone. Every stone can be laid in a dry stacked wall, you just need to see its face.
