Dec 11, 2017 · Utility potholing is used to locate known utilities below surface level by excavating holes. Workers start with a simple pothole of around 8 to 12 inches in diameter and use a vacuum excavator to dig straight down until the utility is found.

Utility potholing is also sometimes called utility daylighting, hydro-excavation, or air-excavation. The technique involves digging a series of non-intrusive, non-destructive test holes to garner as much information as possible about the layout of various utilities on or around a property.

By definition, potholing is a construction method that is done to expose utility lines that are usually located underground. According to Trenchlesspedia, potholing “confirms the location of utility lines on site and any other existing structures that may be within the defined construction area.” ( 1 )

Feb 19, 2020 · The purpose of potholing is to gain onsite confirmation of the location of utilities and any other existing structures that are in the proposed construction zone. During the potholing process, exploratory holes are drilled from the surface to required depths to …

May 28, 2017 · Potholing is an investigative construction method whereby the location of underground utilities is exposed. Potholing involves the drilling of exploratory holes, the depth of which spans from ground level to the required extent of the investigation.

Dec 1, 2024 · Our guide will explain everything you need to know about this topic and how it can help during your next underground construction project. What Is Utility Potholing? Utility potholing is a technique used to locate buried utilities. This can include: More! Small holes are created on the surface so that each utility line can be visually identified.

Potholing offers numerous benefits for construction projects involving underground infrastructure. It helps to accurately locate the exact location of underground utility lines, fiber optics, and other subsurface features, reducing the risk of damage during the excavation process.

Utility potholing, also known as hydro-excavation or air-excavation, requires the creation of a test hole to reveal subsurface utilities. While hydro-excavation relies on high-water pressure to break through the earth, whereas air excavation utilizes air pressure.

Construction crews can use potholing techniques to locate and identify underground utilities with great precision, reducing the risk of accidental damage during excavation. This helps prevent costly repairs, service disruptions, and potential safety hazards.

Apr 13, 2023 · Utility potholing is a method used by excavation and construction teams to safely identify and expose underground utilities. It is a process which requires skill and expertise to accurately locate and identify utilities and prevent damage to them.
