Decomposed Granite Driveways!

Decomposed granite gravel is a versatile organic material prevalent in the construction of garden paths, horse and hiking trails, and decomposed granite driveways. The granite decomposed in many natural hiking areas is an essential part of the ecosystem.

This reddish-brown material begins as mineral rich granite rock and is either already decomposed crushed granite, or decomposes naturally for use in multiple applications. The common places you’ll find decomposed granite are landscaping and gardening beds, where it is used to keep the soil from drying out, underneath hand laid flagstone patios or pavers, and in the driveways and stables of ranches, as well as covering the ground of a dog kennel.  Decomposed granite paths are very common in these types of settings as well.

Using decomposed granite is an inexpensive way to provide a level, mud-free surface to walk or drive on. It is easier to install than concrete and can be done by one or two people in a day. Learning how to install decomposed granite on a driveway is a simple process.

The key to making the laying of your driveway go quickly is proper preparation of the surface. Removing large rocks and smoothing out the dirt area will ensure the decomposed granite installation can turn out level and smooth. For a hard surface driveway, use stabilized decomposed granite, and consider have a professional install it.

For use in a driveway, estimate the amount of decomposed granite for the space and plan on making it three to five inches thick. The added thickness is compacted down with a roller after the initial installation, and is further compacted with daily use. Too much material will simply create additional messes, however, so roll over the first layer or two to better gauge the amount needed.

A driveway or decomposed granite patio is an excellent choice for arid climates as it provides a dry, even path to walk on as well as protection for plant and tree roots. However, for a heavily used driveway or decomposed granite walkway, the material will have to be maintained with frequent sweeping and raking. To achieve a surface with less mess and more hardness, install a layer of stabilized decomposed granite. Mixed with concrete, the stabilized version of this material will set hard, and last longer than its counterpart.

Comparing the decomposed granite cost to other materials like sand, or quarter minus gravel, the crushed granite material comes out at the top, but not by much. The average cost is between three and four dollars a yard, but the additional money spent is worth the warm look and better performing decomposed granite.
