Material glossary
Gravel
Gravel is loose stone in the size range you'd actually notice — pea-sized up to a few inches. Some of it is rounded from a river, some is angular from a quarry. What you pick depends on whether it needs to stay put or drain.
Every gravel family we track is below. Rounded stone reads soft underfoot and drains hard, angular stone locks tight and stays where you put it. We deliver the ones with a green pill; the rest are here for reference.

How to choose within gravel
Foot traffic
Pea gravel and river rock feel good barefoot but shift underfoot; use a border so they stay where you put them.
Vehicle traffic
Round gravel rolls under tires. Pick angular crushed stone for a driveway; save rounded gravel for garden paths and beds.
Drainage
All of these drain well. Bigger pieces drain faster; smaller pieces pack tighter.
