Wisconsin Utility Exposure’s hydrovac keyhole core and restore services provide an efficient alternative to traditional construction on hard surfaces. Core Drilling is a minimally destructive, cost-effective way to expose infrastructure under hard surfaces such as paved roadways, highways, and sidewalks.
Construction and repair projects in areas with already crowded infrastructure are always tricky, and paved surfaces are no different. Not only is there the need to avoid damaging existing underground utilities, crews also need to minimize and repair surface damage as efficiently as possible.
Each project begins with a precision-drilled core that is tunneled through the surface of the pavement or cement to the ground. Once this core “plug” is removed, our hydrovac experts can safely expose the utilities below, negating the risk of ruptured lines and damaged infrastructure during excavation.
Once the utility locating process is completed, it is backfilled and restored using a DOT-approved epoxy that minimizes the appearance of surface damage. In fact, after a properly executed core and restore project, it is typically hard to tell that any work was done on the surface at all.
