Useful questions

Before requesting Class II Road Base

Are price and availability confirmed?

No. This page starts a sourcing conversation. Rio must confirm the variant, quantity, price, availability, and timing before an order.

How do I calculate a useful quantity?

Will the material match the photo?

Do not assume it will. Review the image-truth label, caption, and any credit. Natural materials and current lots can vary; request a current-lot check or sample when appearance is decisive.
