Is crusher run good for drainage?

 · Although it is made from the same type of stone as the other two types, it is crushed into a powder. When used by itself stone dust forms a hard surface that is water resistant. Because of its ability to form a strong, non-porous surface, stone dust is often used in between the stones or bricks in patios and walkways.

Porous Pavement

This porous surface replaces traditional pavement, allowing parking lot, driveway, and roadway runoff to infiltrate directly into the soil and receive water quality treatment. All permeable paving systems consist of a durable, load-bearing, pervious surface overlying a stone bed that stores rainwater before it infiltrates into the underlying soil.
