The recommended batter angle for a dry stone wall can vary depending on the specific circumstances of the wall, such as the height and width of the wall, the size and shape of the stones being used, and the terrain and soil conditions of the site.
In general, a batter angle of between 5 and 10 degrees is considered to be appropriate for most dry stone walls. This means that the wall will slope slightly back into the hill or bank it is being built against, creating a stable base and helping to prevent the wall from toppling over.
However, the exact batter angle used for a particular wall may need to be adjusted based on the specific conditions of the site and the materials being used. An experienced dry stone waller will be able to assess these factors and determine the appropriate batter angle for the wall.
I generally use a 6/1 angle. A 6-1 batter for a dry stone wall refers to a slope of 6 inches (or approximately 15 centimeters) in height for every 1 foot (or approximately 30 centimeters) in width of the wall.
A 6-1 batter angle is considered to be a fairly steep slope for a dry stone wall, and may be appropriate for walls that are particularly tall or wide, or are being built in areas with very steep terrain. However, it may not be the best choice for smaller or more typical dry stone walls, as it could make the wall look too steep or unstable.
Ultimately, the appropriate batter angle for a dry stone wall will depend on a variety of factors, including the height and width of the wall, the slope and condition of the site, the types of stones being used, and the intended purpose of the wall. It is best to consult with an experienced dry stone waller to determine the most appropriate batter angle for your specific project.
Dry stone walls are often built at an angle, known as the batter, for several important reasons.
Firstly, a batter angle provides stability to the wall, helping it resist the forces of gravity and preventing it from toppling over. By sloping the wall back into the hill or bank it is being built against, the weight of the wall is distributed more evenly and its center of gravity is lowered. This makes the wall stronger and more resistant to movement or collapse.
Secondly, a batter angle helps to improve drainage and prevent water from accumulating behind the wall. By sloping the wall, any water that does seep through the cracks and gaps in the stones will be directed away from the wall and allowed to drain away more easily.
Finally, a batter angle can also help to improve the appearance of the wall. By sloping the wall, the stones are arranged in a more natural-looking pattern that follows the contours of the land, giving the wall a more organic and aesthetically pleasing appearance.
Overall, building dry stone walls at an angle is a key element of their design and construction, and helps to ensure their longevity, stability, and aesthetic appeal.
