Installing elevators within existing structures presents unique challenges, but United Drilling makes drilling the hydraulic cylinder hole easy with our unique InsideAir indoor drilling rig. With InsideAir, we bring a full-powered drill rig through a standard 30-inch doorway without disturbing the doorway or the walls.

Our crews have extensive indoor-drilling experience and state of the art technology to drill in any building through any ground—without tearing anything down to get there. And water-tight PVC or Steel liners are available with every hole we drill.
