Decomposed granite quantity for paths, patios, and xeriscape areas, with or without stabilizer.
With these inputs:
| Result | Value |
|---|---|
| Decomposed granite needed | 2.28 tons |
| Volume | 1.63 yd³ |
| Area | 160 sq ft |
| Estimated total | $133 – $236 |
| Area | 160 sq ft |
| Finished depth | 3 in compacted |
| DG volume | 1.63 yd³ |
| DG weight | 2.28 tons |
| DG cost | $91 – $194 |
| Surface type | Stabilized |
| Stabilizer binder | 27 lb (1 × 50 lb bags) |
| Binder cost | $42 |
| Edging (perimeter) | 88 linear ft |
Mix the binder into the DG dry, spread it, then water and compact in 1.5-inch lifts. Stabilized DG sheds water and resists tracking far better than loose DG, at roughly 25% more cost.
Decomposed granite compacts into a firm, natural surface, which makes it the go-to for garden paths and dry-climate landscaping. This calculator sizes both loose and stabilized DG, and adds the stabilizer binder quantity when you need a surface that holds up to traffic.
Two inches for decorative beds, three inches for walking paths, and four inches for patios or areas that see light vehicle traffic. Always compact in lifts rather than all at once.
DG mixed with a binder — usually a psyllium or acrylic-based stabilizer at roughly 12 pounds per ton — that locks the fines together into a firm, water-shedding surface that resists tracking.
Bulk DG runs $40 to $85 per ton delivered. Stabilizer binder adds roughly $40 per 50 lb bag, and a typical path needs about one bag per ton of DG.
