NEED A MAIN WATER LINE OR SEWER REPAIR?

Directional Drilling

Directional drilling is most commonly used for installation or repair of underground pipe, conduit or communication cable in areas where traditional open-cut trenching and excavation is difficult to achieve. Used with many different types of pipe or conduit materials including PVC, ductile iron, steel, polypropylene and polyethylene, as long as the pipe has the thickness and material strength to withstand the stress, it can be utilized. The amount of ground surface needed for directional drilling is minimal, since with the exception of the entry and exit sites of the drill bit, almost all drilling is done underground.

Trenchless Sewer & Water Line Repair

The beauty of trenchless sewer and water line repair is that doesn’t require digging up lawn or walkways. With a variety of advanced techniques at our disposal, we can ensure your yard stays intact while we repair your pipes.

Sewer Pipelining

When it comes to sewer pipeline repair, one popular technology we employ is pipelining. This method involves inserting a new pipe inside the old, compromised one. It’s cost-effective, efficient, very effective ansd minimally intrusive.

Underground Power Line Work

Underground power lines increase the natural outdoor aesthetics of your property, and have been proven to be just as effective as the above-ground alternative. When installed using trenchless technology, landscaping, parking lots or other outdoor areas of your property aren’t disturbed or destroyed. The experienced pros at Master Bore will leave your property looking the same as when we first arrived!

Signs That Underground Utility Repair May Be Needed

Though you may not yet be experiencing a serious or disruptive incident related to your water pipes or sewer, call us if you see any of the signs of trouble below. You could save tens of thousands of dollars by heading off major damage and repair.



  • Corrosion in the soil around underground piping: Concentration of corrosive materials in the soil in city environments is usually much higher than in rural areas. Over time, corrosive soil conditions can eat at piping until it becomes brittle enough to break.

  • Changes in water pressure: If your main water line has been weakened from corrosion over time, changes in water temperature inside the line can cause pressure changes that can cause line failure. This can also occur when fire hydrants are opened and closed improperly.

  • Interruption of underground utility service due to construction work: When contractors or homeowners aren’t careful where they dig, it’s possible to unintentionally damage or break water pipes. Immediate attention is then required!

  • Aging water pipes: Piping becomes brittle and breaks more easily as it ages, especially if made of cast iron which doesn’t flex with changing water pressure.
