Test Dig: Presco Underground Non-Detectable Warning Tape

We wanted to know exactly how other marker tapes on the market performed, so we tested them ourselves. The analysis of Presco Underground Non-Detectable Warning Tape (Part # PRESCO B6104Y5) consisted of six digs, two of each at 90, 45 & 180-degree angles of approach using a standard 30” bucket. The tape was installed about 1’ below grade, covered, and mechanically compacted under the weight of the track hoe. Digs were performed in an effort to maximize the visibility of the marker tape. Each dig was stopped once visible indication of marker tape was confirmed by the equipment operator/spotter or when it was determined the tape was struck and no visible indication was provided.
