Decomposed Granite

If you are looking to make a comfortable walkway in your yard or change the design of your garden, you have probably come to know about decomposed granite. A pathway of decomposed granite gives you an aesthetically handy look. This hardscape material is also very much cost-effective, penetrable, and natural. So, the use of decomposed granite or DG is the best way to avoid the simple dirt and muddiness of your yard. Let’s take a look at what is decomposed granite and how we can use it to make pathways.

What is Decomposed Granite?

Decomposed granite is simply a type of rock that comes from the weathering of granite. Due to weathering, a granite parent rock breaks into pieces of weaker rock and then again into gravel-sized particles. These particles further break into a mixture of silica sand, clay, and silt particles. The mixture of different granite types produces decomposed granite which is more stable and finer than gravel. There are various shades of DG including gray, red, green, and black.

Types of Decomposed Granite:

You can have a variety of decomposed granite with different grades of particle sizes and in more than 30 different colors. Nevertheless, there are three main classifications of DG depending on the form, such as natural, resin-coated, and stabilized.

How to Create a Decomposed Granite Pathway?

There are certain things that you require to create or install a decomposed granite pathway. First of all, if you are building a path or patio, it is better to use stabilized DG. Whereas you have to use the resin-coated DG for driveways and natural DG for garden beds and spreading around trees. For installing a DG pathway, you will also need header boards, a compactor, rake, pattern drawing instruments,            measuring tape, paper, pencil, and a calculator.

Follow these three simple steps to make a decomposed granite pathway-

  1. Try to locate and visualize your path with the help of header boards. Draw a layout and excavate the path down up to 3- 4 inches.
  2. Calculate the required amount of decomposed granite considering the area and depth of your path.
  3. Use header boards to preserve structural integrity.
