Crushed Stone Under Concrete: Why It's Needed

Crushed stone under concrete provides a level surface for you to lay your foundation on. If you pour concrete directly over the ground, it could erode away over time, and this would cause your slab to sink. The solid foundation that the crushed stone provides will offer the support the concrete needs.
