What is decomposed granite gravel

Compared to loose DG, stabilized DG is more expensive, but it's still less money than pavers, decorative concrete and natural stone. Once spread and compacted, DG with a stabilizer will look similar to loose DG, with the top layer appearing loose and organic. However, stabilized decomposed granite will be less susceptible to erosion.

As a result, it has a longer life span and requires less maintenance than loose DG. Many landscaping companies will deliver DG with a stabilizer already mixed in. Decomposed Granite with Resin - This is the most costly type of decomposed granite. Resin is added to the DG, creating a surface similar to asphalt. Sometimes called poly pavement, DG with resin is the strongest and most durable DG option, making it great for driveways and high traffic areas.

The look will not be as natural as loose or stabilized DG, but it will be much more durable. Pavements made with DG and resin will not erode or be tracked away. One downside to selecting the resin option is that the drainage is nowhere near as good as loose or stabilized DG. Laying Decomposed Granite Laying decomposed granite is a fairly quick process. First, the area where the DG paving will be laid will be excavated.

Then, a weed barrier, such as landscaping fabric, should be laid down and landscape edging should be installed around the perimeter. Next, the DG will be placed and compacted. At this point, your patio, walkway or driveway is ready to be used. Decomposed granite is a versatile and robust material that can be used in everything from the trails and Erin Hills Golf Course to the Downtown East Commons at the U.

Bank Stadium. You may require a product that offers more stability and durability. Your pathway might need to be able to withstand heavier traffic, or your ballyard may need the moisture-retaining properties of an organic binder to minimize dust and mud.

Kafka offers several crushed granite mixes that have been engineered to support high traffic areas, such as our stabilized and wax polymer pathway mixtures. Whatever the reason, crushed granite can be stabilized with natural binders such as Organic-Lock and Stabilizer Solutions. These binders help create a durable surface that resists the erosive powers of weather or heavy traffic—all while maintaining the natural aesthetic you may have been going for in the first place.

This means stabilized decomposed granite is an excellent alternative to obtrusive or less-natural looking asphalt or concrete pathways, driveways, etc.

For the highest level of erosion resistance and durability, the Kafka Granite wax polymer pathway mixtures is an optimal solution. This hearty mixture can withstand intense erosion and be laid on the steepest of hills, due to its completely sealed, impermeable surface. However, this surface yet retains a natural aesthetic and can be easily maintained and manicured over time, unlike traditional hardscape materials.

Decomposed granite can be purchased in a variety of ways. It is usually easier for smaller-scaled operations to source our aggregate mixtures from a member of our expansive dealer network. With dealers spread out all over the Midwest, finding a Kafka Granite supplier near your next project is easy. When it comes to large-scale projects, we most commonly assist contractors, architects, and designers by providing direct quotes for their architecturally specified projects.

With a versatile portfolio comprising standard, stabilized, and wax polymer pathway mixes, we can help any project find its ideal pathway mixture. But the short answer to the question is that the price of this material can vary greatly, due to the variety of DG available. Factors like size, color, market price, shipping, and whether or not the aggregate needs to be stabilized will affect the ultimate price of the product. Before you begin your search for the right material, hone in on the key features that you will need, such as color and the amount of traffic or weather the product will need to withstand.

Ask yourself the following questions:. A sieve analysis is used to guarantee that every shipment of product contains the right proportions of stone sizes. If you choose a product that does not meet specifications or other quality standards , you run the risk of installing a low-quality product.

There are several ways in which decomposed granite can contribute to your LEED certification efforts. Striving to build a green, eco-friendly project will benefit the environment for years to come. This is an ideal stabilizer because it requires little to no maintenance, does not fail over time, and has excellent erosion control.

It is also permeable, allowing water to easily pass through; since it does not contain any oils, resins, polymers, or enzymes, it will not cause water pollution. Decomposed granite always has a sieve analysis associated with it. The sieve analysis is the percentage of sizes of the aggregate particles. The sieve analysis of DG that creates the best GraniteCrete installations is below. As one can see, these ranges vary without affecting the integrity of the final installation.

Decomposed granite that falls within the ranges noted above are found throughout California. Ask the supplier to provide a sieve analysis of the decomposed granite they provide.

Please take the time to find a decomposed granite that meets our specifications. We are happy to review it to ensure an acceptable DG is used. An example of decomposed granite. During compaction, the fines will rise to the top. The mixture will be difficult to work. As a result, surface imperfections will be tricky to remove and creating an acceptable finish will be difficult.

Reduced final permeability. Larger stone creates voids in the final installation; these voids allow water to pass through to the ground below. Linden Park: The Metamorphosis of a Space.
