How stabilized DG differs from loose DG, the binders sold for it, one manufacturer’s install specs step by step, and what to expect in the High Desert.

The binder is usually a plant-based powder, a liquid polymer or a resin. How well it lasts depends mostly on the base under it, the blend, the water and the compaction.
Loose DG erodes, needs topping off and tracks indoors (Landscaping Network). Stabilizing it is the usual fix for paths and patios. This page is part of our landscape rock and decomposed granite guide; for DG basics and colors, start with the decomposed granite guide.
Plain DG packs down when you compact it, but nothing holds the particles together. Water and feet move them, so the surface ruts, puddles soften it, and fines wash to the low end of the path.
Stabilized DG adds a binder that locks the fines together once it is wet and compacted. The result is still DG to look at, with the same color and texture, but it walks more like a firm surface. It is not pavement. Some loose material always sits on top, and the binder only works if the base under it is solid and water drains away.
Stabilizer Solutions, a Phoenix manufacturer, says its binder works with DG, crushed stone and limestone (Stabilizer Solutions). That means “stabilized DG” can also be stabilized crushed stone in a different color.
Suppliers sell three main kinds of binder for DG (Low Desert Rock Supply, Kafka Granite). Each product has its own mix rate and install steps.
| Binder type | What it is | What to know |
|---|---|---|
| Organic powder | Plant-based powder mixed dry into the DG. One maker’s product is crushed seed hulls (Stabilizer Solutions). | Activated by water, then rolled. The install steps below are for this type. |
| Liquid polymer | A liquid binder mixed or applied with the DG | Follow the polymer maker’s guide; steps differ from powder. |
| Resin (epoxy or similar) | Resin that binds DG into a hard surface | Closest to an asphalt-like finish (Landscaping Network). |
Our sources for binder types are supplier guides, so we have kept this to what each type is. Ask the binder maker for its data sheet before you pick one.
Source for every step: Stabilizer Solutions. The same guide gives coverage of about 65 sq ft per ton at 3 inches deep. You can check order sizes with our landscape rock and DG calculator, and see how stabilized DG fits into a full path build in our DG pathway how-to.
The same Stabilizer Solutions numbers in one table, for checking a bid or a plan (Stabilizer Solutions):
| Item | Manufacturer spec |
|---|---|
| Base | 3 inches state DOT crushed road base, pre-soaked, compacted to 95% |
| Binder rate | 12 lb per ton (planting areas), up to 15 lb per ton (heavier use) |
| Mixing | Mechanical, pre-mixed dry; not bucket blended |
| Finished depth | 3 inches light traffic, 4 inches high traffic |
| Lifts | Over 3 inches goes in lifts; 4 inches as two 2 inch lifts |
| Water | 25 to 45 gallons per ton, through the full depth |
| Compaction | Wait 6 to 48 hours; 3 to 4 passes, 1,000 lb roller or 1 to 5 ton double drum, to 85%; no vibratory plate |
| Weather | Not in rain, not below 40°F and falling |
| Coverage | About 65 sq ft per ton at 3 inches |
The US Access Board says floor and ground surfaces on an accessible route must be firm, stable and slip resistant (US Access Board). A well-built stabilized DG surface is firmer than loose DG.
That does not make stabilized DG compliant by itself. Whether a path meets accessibility rules depends on how it is built: the base, the compaction, the slope, edging and upkeep. If a path has to meet those rules, for a business or a public space, have it designed and checked for that purpose.
We could not find a solid source for a number of years, so we will not give one. What the manufacturer does describe is the first year. Expect 1/16 to 1/4 inch of loose material on top. That is normal. If it builds past 1/4 inch, redistribute it, wet the surface about 1 inch deep and roll it again (Stabilizer Solutions).
The rest of the upkeep comes down to water. The guide says no water should stand on or next to the surface, and to watch where roof downspouts empty (Stabilizer Solutions). Keep sprinklers from spraying it every day, and fix low spots early, before they spread.
Stabilized DG tends to do better than loose DG here. It still needs a plan for a few things.
Monarch installs stabilized DG paths as part of rockscape work. See our Apple Valley rockscape and Riverside rockscape pages.
It is DG blended with a binder, usually a plant-based powder, a liquid polymer or a resin. After it is soaked and rolled, the binder holds the fines together so the surface is firmer and resists erosion better than loose DG.
The Stabilizer Solutions guide calls for 3 inches after compaction for light traffic and 4 inches for high traffic, over a 3 inch compacted road base. Other binders may have different specs, so check the product guide.
Not with the Stabilizer Solutions product. Its guide says to use a roller and not a vibratory plate, because vibration separates the aggregate. It calls for 3 to 4 passes with a 1,000 pound roller or a 1 to 5 ton double drum roller.
Not by itself. The US Access Board requires accessible route surfaces to be firm, stable and slip resistant. Stabilized DG can help meet that, but compliance depends on the whole install, including base, compaction, slope and upkeep.
Some loose material is normal. The manufacturer expects 1/16 to 1/4 inch on top in the first year. If it gets thicker than 1/4 inch, redistribute it, wet the surface about an inch deep and roll it again.
We checked every number on this page against the public sources below. If a rule or date changes, the agency page is the final word.
A stabilized path is only as good as its base, grading and compaction. Monarch builds rockscapes and DG paths with the drainage to match. Get a free estimate and we will tell you whether stabilized DG fits your yard and your traffic.
