If you are imagining decomposed granite as huge pieces of granite boulders then you are mistaken. Decomposed granite is actually gravel material derived from granite of course. Therefore, for it to actually become the gravel material it is granite boulders must have been exposed to agents of weathering for millions of years. With the passage of time the gravel is eventually formed, providing a good source of construction material. This granite can be used for a variety of purposes, some of which will be revealed in this article.



There are different types of decomposed granite out there. There is: decomposed granite with resin and stabilizers and loose granite. Loose granite is the cheapest and it is sold in a raw form that hardly contains an additives. On the other hand, decomposed granite with stabilizers is firmer and has a really loose surface. As for decomposed granite with resin, it is more compact when complete. All these types serve different purposes and of course their prices differ.



The very first thing you must know about this gravel is that it has a very coarse and rough texture, unlike smooth soils like loam and clay. Because of this inherent inner structure, it can be effectively used as filler material for foundations. When you use this material for the construction of your foundation you will be really impressed to note how well it can also drain out water. In addition to being a wonderful filler material it is also good at draining soils underlying a foundation, thereby preventing the collapse of such a structure.



You can also use this type of granite for pathways, walkways and patios. When making a decomposed granite path, you must make sure that you get rid of all the debris on the site. You must also make sure you at least clear away the site for the pathway to allow for 3-4 inches of granite. When you are done with this, you must then proceed to lay out your granite and push it into the ground with a roller. The main reason why this granite is perfect for pathways is its low water retention. Since it does not absorb any water, it is good to use in the rainy season in areas where you normally experience puddles of water.



Apart from this, you can also use this granite on hiking and biking trails. Decomposed granite creates good friction and helps to reduce the occurrence of accidents.
