With the proper tools available on-site, first excavate existing site materials and compact foundation soils. Then, create the leveling pad by installing and compacting 6 inches of crushed road-base aggregate, and ensure it's level front to back and side to side. Next, place the base course—which becomes your embedment—and ensure that it's perfectly level front to back and side to side. Add subsequent courses, and place and compact drainage aggregate and backfill every 6 inches while including any geogrid. Finally, add cap units and final landscaping to finish the SRW !
