Petra is designing and building a new type of underground drilling and boring system. Their Swifty robot is semi-autonomous and utilizes a non-contact thermal drilling method that can uniquely bore microtunnels below 60 inches in diameter through hard rock, meaning it’s now possible to bore utility tunnels through previously impenetrable geologies. Swiftly will enable customers to rapidly bury critical utilities for a fraction of the cost of legacy techniques—which includes: construction services, tunnel development, and ongoing maintenance.
