Frequently Asked Questions
How deep should decomposed granite be?
For pathways, use 2-3 inches of DG over a compacted subgrade. For patios and driveways, use 3-4 inches. For decorative ground cover, 2 inches is sufficient.
What is stabilized decomposed granite?
Stabilized DG has a natural resin binder mixed in that, when compacted and watered, creates a firm, erosion-resistant surface. It is more durable than loose DG and suitable for higher-traffic areas.
How much does decomposed granite cost?
Bulk DG costs $30-$70 per ton depending on color and region. Stabilized DG costs more due to the binder additive, typically $50-$100 per ton including stabilizer.
