"Project Cornerstone is an Award Winning Organization"

Construction aggregates are the second most consumed commodity in the world
- second only to water.

Examples of construction aggregates are sand, gravel, and crushed stone.

Project Cornerstone is a grassroots organization dedicated to educating the public about the importance of local construction aggregate resources through hands-on learning in Science, Technology, Engineering and Mathematics (STEM).
