Warning Mat
Warning Mat is a protective underground safety tape or mesh installed above buried cables or pipelines to provide a visible warning during future excavation. It helps prevent accidental damage to electrical, telecom, gas, or water lines. A warning mat is typically made from HDPE or polypropylene mesh in bright colors with printed caution text. It is laid 300–450 mm above the buried utility line to alert workers before they reach the actual cable or pipe.
