Purpose-Built for Underground Water Infrastructure.
TrenchMark detectable warning tape combines APWA-standard color coding with Armor-protected RF electronic markers — giving excavators a visual warning at the trench face and a locatable signal from the surface.
Four models. One integrated system.
Each TM-2000 Series model is pre-configured for its utility type — correct color, correct warning language, correct RF frequency.
