    Keyhole Technology

    Keyhole technology involves a rotary cutting unit, or core drill, that safely and accurately cores up to 18-inch diameter hole through asphalt, asphalt-concrete and reinforced concrete road systems, and sidewalks to enable crews to vacuum excavate and view subsurface activity or to repair underground plant from the road surface using long-handled tools. The Landshark unit incorporates a Utilicore unit attached to a Bobcat for ease of use on busy streets with minimal disruption. Cores are reinstated using a bonding agent that sets up quickly for traffic flow resumption.
