Expert Verdict Reviewed by the SuperArbor Pro Desk

Bottom Drain is best specified as the drainage layer behind retaining and foundation walls where water must be captured and routed away from the structure. Because it is modular, layout flexibility is good around penetrations and corners. For blindside and backfilled wall applications, coordinate it with the applicable AVM System 590 detail drawings and pair with bentonite sealant and granule details at terminations.

Below-grade drainage work involves excavation; shore or slope trenches as required and follow local building codes and OSHA excavation safety practices.
