Project Cornerstone's mission is to educate the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone) through hands-on learning in Science, Technology, Engineering and Mathematics (STEM). Construction aggregates are used to build roads, houses, schools and all other infrastructure; they are the cornerstone of our communities.
