The Science of Stability: Open vs. Dense Graded Bases for Driveways

The choice between open-graded and dense-graded bases for Lowcountry driveways depends on drainage needs and soil stability. Dense-graded bases, composed of crushed stone and “fines,” offer maximum load-bearing strength for heavy vehicles. Open-graded bases, using larger, uniform stones without fines, provide 30–40% void space for superior drainage—making them the ideal solution for Lowcountry properties with […]
