Petra's mission is to protect life and property by changing the feasibility of undergrounding utilities. We want to make undergrounding possible and affordable in every region and for every community in the world. Petra's tunneling robot bores through the hardest, most abrasive ground conditions on earth. Petra's semi-autonomous non-contact tunneling robot utilizes a non-contact thermal drilling method that minimizes surface disruption while promoting efficient drilling. Powered by machine vision, Petra's tunneling robot microtunnels through the hardest geologies faster and more reliably than conventional methods, and can bore through rock considered too challenging for other tunneling machines. Petra is able to bore through the hardest geologies on earth, enabling customers to underground utilities in difficult geographical regions most at-risk for wildfires and hurricanes.

Above-ground utilities are vulnerable to natural and man-made threats. Petra is transforming grid infrastructure to make undergrounding more accessible for ALL communities. Petra's undergrounding robot bores utility tunnels through the hardest rocks on earth—which are often located in the most fire and wind prone areas—faster and cheaper than conventional methods.

The damage to above-ground grid infrastructure during wildfires and storms can be catastrophic. We need new methods to protect life and property in the face of increasing disasters. Petra provides tunneling construction services for cities, utility companies, government facilities, development projects, and more. Petra has the proprietary technology and geological expertise to overcome any utility undergrounding challenge.
