You should now have the necessary knowledge to install a Standard unit SRW!

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!
