Missile bore is a trenchless technique used for short, direct runs to place conduit beneath obstacles with minimal surface disruption. It works by launching a small projectile (the missile) from one side to the other and pulling in a conduit behind it, making it ideal for crossing under sidewalks, driveways, and roads where the distance is brief and straight. For longer distances under highway corridors, methods designed for extended bores, like HDD, are more appropriate. Vertical drilling through rock involves a different approach suited to hard rock conditions, and underwater crossings require methods that manage water sealing and stability, which missile bore isn’t typically used for.
