With both safety and project longevity at the forefront of our process, we are notorious for over engineering our driveways to avoid settlement and tire rutting. Beginning with excavation we dig a minimum of 15" from top of grade and extend the base 16" on all sides. Then we run a diesel packer with the ability to compact up to 24 inches at a time over the sub-grade, the base materials and our bedding material to maximize particle lockup. 

Our base materials are set on top of a non-woven and permeable geo-textile to separate our base and the sub-grade. Then we typically add 11" of 3/4" crushed angular stone which is fully permeable and comes at 98% Proctor Compaction Rating, followed by our 1" bedding layer of High Performance Bedding (HPB - 1/8") Stone also fully permeable. These base materials will not degrade overtime and with proper compaction practices will stand the test of time. We also use a fiber reinforced concrete edge restraint to both lock in the interlock border as well as the bedding layer to ensure no base material are pushed out due to vehicle weight. 

Not all interlock is created equal. We always advise using interlock that is a minimum of 3-3/8" in thickness and is driveway rated. Or if you would like porcelain we always advise poring a concrete base for the porcelain to create a strong and durable driveway.
