The first Drainage Pipe made specifically for yard Drainage, crawl space, interior basement de-watering, and exterior basement waterproofing. Baughman High Octane needs 1″-2″ aggregate to get the most out of its industry-leading 17 plus square inches of inlet per linear ft. The inlets are so large sediments wash through the pipe instead of plugging the pipe allowing for an open French drain that is not fully wrapped and contained. Baughman High Octane takes in water faster than any other Drainage pipe on the planet. The industry leader is performance and reliability the Baughman High Octane is 2nd to none!
