Northtown's Non-Detectable Underground Warning Tape consists of a 4mil overall thickness of polyethylene film formulated to resist degradation due to acid and alkaline soils. The lettering on all non-detectable indicator tape is a minimum of 1" unless otherwise specified. All non-detectable warning tape is APWA color coded and permanently printed. Non-Detectable tape is used for accurately locating and preventing damage to valuable underground utility installations. Properly installed, this tape helps avoid catastrophically inaccurate digging when locating utilities such as electrical lines, gas pipes and communication cables.
