We specialize in directional boring, a less-invasive way to install pipe. Both cost-efficient and fast, HDD boring is trenchless and can be used to install pipe beneath waterways, roads, buildings, and congested areas. Its minimal-impact application makes it a great option for environmentally sensitive areas or any area where other methods are too costly or insufficient. Some common applications for HDD drilling include power conduit installation, telecommunication conduit installation, driveway sleeves, and more.

We’re trusted throughout the Mid-Willamette Valley as a provider of underground utility construction and site work, ranging from sanitary and storm sewer installation to waterline, gas, and communication line installation; vactor excavation; sewer line locating and scoping; pipe bursting; and HDD drilling.

When regular excavation isn’t possible, AUi has the vactor excavation equipment necessary to determine the accurate depth and profiles of existing utilities, locate utilities for drill shots, and find existing utility infrastructure for our clients. Vacuum Excavation can be used when regular excavation isn’t possible, such as for critical tree root excavation, utility location, and in tight spaces.

As one of the few companies in the area with the ability to perform exterior sewer replacements and repairs through the convenient process of pipe bursting, AUi can correct cracked, broken, or collapsed pipes; root infestations; and groundwater infiltration. With this method, we can fully rehabilitate and upsize segments of failing infrastructure and minimize costly surface restorations in a timely and less-invasive manner.
