What’s included
What we install
What can you build with decomposed granite and river rock?
Decomposed granite makes firm, walkable paths, patios, seating areas and stabilized driveways. River rock makes planting beds, borders, dry creek beds and drainage channels that move water. Most Las Cruces yards use both: DG where people walk and river rock where water flows.
DG paths and walkways
Natural-looking paths that pack firm, drain well and cost far less than pavers or concrete.
DG patios and seating areas
Level gathering spaces for chairs, benches and fire pits, often edged with steel or pavers.
Stabilized DG driveways and parking pads
Deeper, binder-treated DG that holds up to cars and resists washing out.
River rock dry creeks
Channels lined with cobble and boulders that carry monsoon runoff and look like part of the landscape.
River rock beds and borders
Rounded rock around plants, foundations and downspouts, where it resists splash and erosion.
Boulders and accents
Hand-placed boulders to anchor beds, hold slopes and add height to flat yards.

Your options
Should you use natural DG, stabilized DG or river rock?
Use natural DG for low-traffic paths and patios, stabilized DG for driveways, busy paths and gentle slopes where dust and washouts are a problem, and river rock for beds, borders and dry creeks. River rock stands up to runoff best but is loose underfoot.

Myth vs. fact
“DG is just dirt.”
Fact: installed right, DG is a graded, compacted surface you can walk, sit and set furniture on, for a fraction of the cost of pavers.
Myth vs. fact
“River rock stops weeds by itself.”
Fact: weeds still grow in the gaps. Weed barrier, enough depth and a pre-emergent in late winter make the difference.
How it works
How is decomposed granite installed?
We lay out the area, remove weeds and soil, grade a slight slope for drainage, set edging on every side, then spread DG in layers, wetting and compacting each one. For river rock we lay weed barrier first and place rock by size, largest where water runs.

Done right
How do you make decomposed granite last in Las Cruces?
DG lasts when it sits on a compacted base, goes in 3 to 4 inches deep for paths and 4 to 6 for driveways, is wetted and compacted in layers, has edging on every side and a slight slope to drain, and uses stabilizer where traffic or runoff is heavy.

Where river rock works best
Local know-how
What should you know about DG and rock in the desert?
In Las Cruces, loose DG fines can blow in spring wind, heavy monsoon storms wash DG off slopes, and very light DG reflects heat and glare. Stabilized DG near doors, river rock where water flows and warmer tan colors solve all three problems.
Wind and dust
Loose DG fines can blow in spring wind. Stabilized DG and a good compaction keep dust down near patios and doors.
Monsoon runoff
Heavy storms wash DG off slopes. We use river rock where water flows and stabilized DG where it can’t be avoided.
Heat and glare
Light DG reflects heat and glare. Warmer tan and brown tones stay more comfortable around patios.
Caliche
Caliche can make a firm base but blocks drainage. We grade so water leaves the surface instead of sitting on it.
Tracking indoors
DG sticks to shoes when wet. A paver or flagstone landing at doors cuts down on tracking.
Water-wise
DG and rock need no water, fitting City watering rules and xeriscape designs.
