The first step in constructing a sandstone wall is to lay the foundation. Dig a trench that is slightly larger than the wall. Apply a thin layer of mortar. This will fill in any cracks in the foundation and provide a smooth surface for the building blocks. Using a level, make sure that the level line is between 300 and 400 millimeters above the footing. Once the foundation is in place, start setting the stones in order. It is important to choose stones that are large and stable. Avoid round back stones as these will be harder to build on. Also, choose stones that are free-draining and flat.
If you want your wall to be sturdy, you will need to heart the stones. This adds many points of contact between the stones, which keeps them from moving independently. When placing the stones, be sure to use large stones nearest the wall and smaller ones farther away. You should also sort the stones into big, medium, and small sizes to maximize the strength of the wall.
Next, you must compact the gravel and level it. Then, place the stones evenly on top of the gravel. Use your builders level and a tape measure to make sure that the stones are level. Ensure that the stones are flat, and that they overlap the joints between the stones below them.
Using different shapes is another way to add variety to the wall. It is important to keep in mind that different types of stones are different from each other, so be sure to keep this in mind when selecting the stones. Stones that are difficult to work with should be used sparingly throughout the wall so that the overall structure of the wall doesn't break down. Another way to improve the wall is to break the stones into small pieces, which will make them easier to use.
When building dry stone walls, it is important to keep in mind the importance of the batter. This adds strength, stability, and efficiency to the building. The batter is the ratio of run to rise in a wall, and it can range from 1:6 to 1:10. If you don't have this factor, you'll have a wall that looks poorly, and is not structurally sound.
Stone wall building can be challenging, but it's not difficult. Stones of any shape and style can be used. However, don't opt for flat stone, as it takes longer to build. Choose a stone that is smaller, as this will give the wall a more refined look. The process of building a stone wall requires a lot of physical work, and it will take anywhere from two to seven days. It is important to observe the landscape before starting work, and pay attention to the natural runoff of water.
