  • Efficiency

    Leveraging keyhole coring techniques, contractors and municipalities can perform maintenance to underground utilities through small cored-pavement openings rather than traditional, large excavation methods.

    The coring technique is physically less demanding for workers, eliminating the need for jackhammers and backhoes.

    This technique also offers significant cost savings. Faster and more efficient utility repairs minimize surface disruption and reduce the public inconvenience from having roads closed and traffic diverted for long periods of time.

    Today, keyhole coring technologies are approximately 50 percent less costly than traditional excavation repairs and disposal removal.

    The process is permanent, requiring no temporary patching, repaving or revisits. Today, the simple, efficient process is field-proven with more than 100,000 successful core reinstatements and no reported failures in more than 20 years.

    The process is fast. Roads can reopen to traffic just 30 minutes after core is reinstated.

    Coring has a reduced carbon footprint, up to 12 times smaller than traditional excavation and repair methods.

    Using Utilibond™, the specially engineered pavement bonding compound, the reinstated core is permanent and field-proven to be effective for over 10 years.

  • Reinstatement

    In addition to the MTC100 coring attachment, Utilicor provides the market-leading reinstatement material Utilibond™.

    Capable of supporting up to 50,000 lb in just 30 minutes, this specially engineered pavement-bonding compound results in a permanent pavement repair that reduces public inconvenience, requires no additional paving materials and is field-proven to be effective for more than 10 years.

  • Versatility

    Using a construction-grade Ditch Witch mini skid steer with a Ditch Witch MTC100 coring attachment, the keyhole coring process is simple and allows operators to make quick and accurate cuts up to an 18-inch diameter hole, up to 22 inches deep. Vacuum systems are then used to excavate down to the utility for maintenance from the road level, and once complete, the original core is re-inserted after the repair with no patching or repaving required.

    Coring can also be used for potholing—to remove concrete or asphalt—then use a vacuum excavator to visually verify or expose underground utilities to prevent damage. Using coring to pothole is much faster and less intrusive than the traditional process of using a jackhammer or saw.

  • Design

    The MTC100 is equipped with a 20-gallon external water tank and half-inch diameter water hose to help cool the cutter head and an additional auxiliary hose and nozzle provides additional cleaning support and cooling of the cutter as needed.

    The unit is fully welded from 1/4-inch gauge steel, with a quick attachment system to ease use and set up with mini skid steer machines.

    The hydraulic system utilizes quick connect auxiliary hookups. This “plug and play” feature allows operators to be ready to core within minutes.

    The compact machine is easy to maneuver and can accurately work in confined spaces, including sidewalks, where larger truck-mounted machines would not fit.

  • Power

    An integrated control panel displays orbital and feed pressure gauges for insight into machine production. And speed is fully adjustable from zero to 280 rpm for enhanced control and productivity.

    Used in tandem with the mini skid steer, the attachment can cut up to an 18-inch diameter hole, up to 22 inches deep for minimal surface disruption.
