Decomposed granite (DG)is a relatively inexpensive, casual paving material which can be used for many different kinds of hardscapes. I say "relatively" inexpensive because there are different applications. As these various installation processes get a bit more involved, the costs increase. However, in its most simple form, it really is one of the less costly paving options.

DG can have a sandy consistency, or the granules can be a bit larger. Its longevity depends on they type of DG used.

There are three types of installations methods.

Loose Decomposed Granite

Loose DG is where the material is used alone. Although it is the least expensive, it is not considered permanent, as it will have to be added to occasionally. This is due to the fact that it can erode and it is not a firm material. Picture a sandy walk which is slightly compacted and that is what loose DG is similar too.

When using this type of application, I would strongly recommend using an edging to hold the DG in place. This can be a steel edging, or something more intricate (and expensive) such as a brick border. The edging, as mentioned, keeps the material in place and from spreading onto adjacent areas, such as lawn.

When using this type of decomposed granite along with steel edging, the cost should be similar to that of concrete.

DG With Stabilizers

In this application, the material is mixed with stabilizers so that a more firm and harder packed substance is created. It will last for about seven to ten years. It is more expensive, but then again, it is important to weigh how important a longer lasting paving material is in the specific area.

DG With Resin

A resin is mixed with the DG. This is the hardest and most firm application. It may or may not have a loose finish on the top layer. There is no problem with erosion and it is the longest lasting of the three types.

DG with stabilizers and with resin can be mixed by your contractor at the project or it can be shipped to the site pre-mixed. The latter is more costly; shipping costs can be quite high.

Areas To Use Decomposed Granite

This material can be used for any hardscape projects where a more casual or rustic look is desired. There are even different color choices. Consider the following:

• Residential Walkways

• Garden Paths

• Woodland Paths/Walking Trails

• Driveways
