Walkways commonly use 2-3 inches over a compacted base; patios may need 3-4 inches depending on soil.

What does stabilized DG mean?

Tips & notes

Assumptions that most often change the final quantity in the field—so you order with clearer eyes.

Use stabilized DG where foot traffic, slopes, or erosion are concerns.

Compact in thin lifts and mist lightly between passes.

Crown paths slightly so water sheds instead of ponding.

Plan edging to keep the fine aggregate contained.
