  • Composite manhole cover with embedded detection
    Patent number: 11525235
    Abstract: A composite manhole cover includes a body made of a polymer that has a mass of magnetic material embedded there within. The mass of magnetic material is detectable by a metal detector and, therefore, the composite manhole is locatable by the metal detector when the composite manhole cover is obscured by a material such as pavement, dirt, sand, grass/sod, etc.
