•Modestly compact the sidewall area backfillmaterial by simply walking down the sides of thechambers. Sidewall compaction is important tobeginthestabilizationprocessofthesoil,tosupportthe chamber sidewalls, and help prevent fine sandmigration into thechamber louvers.Thisproceduremaybeaccomplishedanytimeduringtheinstallationorcoveringprocess.

•All ARC chambers are H-10 load rated. Wherevehicular loading is anticipated during installation ofthesystemorconstructionofthefacility,H-10loading(16,000 lbs/axle) is achieved by backfilling with aminimumof12"ofproperlycompactedcover.•Do not drive heavy equipment over a system comprisedofnon-compactedcovermaterialwithout first bridging the excavation. Use lightweight or trackedequipmenttopushthesoilontothesystemto theproperheightsetforthbylocalandstatecodes.

Innovation in product, process and technology.

That’s ADS and Hancor.

Beginning with single wall corrugated polyethylene pipe, ADS and Hancor have

continually introduced drainage products that have set the industry standard –

bringing to market a remarkable alternative to concrete and steel pipe. Our

commitment to being the best means that we continue to refine the structural

design of our pipe and redefine the limits of its application in the structural

design community.
