Utility Location and Daylighting in Dallas-Fort Worth, TX

Utility locating typically refers to finding the approximate position of buried utilities using electromagnetic, ground-penetrating radar, or other detection methods. Daylighting takes it a step further by physically exposing the utility so it can be visually confirmed. Locating tells you roughly where a line is; daylighting lets you see it, measure it, and verify its depth and condition. Hydrovac is the preferred method for daylighting because it removes soil without risking damage to the utility.

Yes. Texas law requires that you contact Texas 811 at least two business days before any excavation, including hydrovac work. The 811 process notifies utility owners so they can send locators to mark approximate positions. Our hydrovac daylighting then provides the physical verification of those marks. We can coordinate with your 811 ticket to make sure timing lines up with our scheduled work.

ASCE 38 defines four quality levels for subsurface utility data. Quality Level D is the least reliable, based only on existing records. Quality Level C adds survey-visible surface features. Quality Level B uses geophysical methods like GPR to approximate position. Quality Level A is the highest standard and requires physical exposure of the utility, which is precisely what hydrovac daylighting delivers. If your project specifications or your SUE consultant requires Quality Level A data, hydrovac is the way to get it.

The Blackland Prairie soils across the DFW Metroplex contain high concentrations of expansive clay that swells significantly when wet and shrinks when dry. This seasonal movement can shift buried utilities away from their original installed position, making record drawings unreliable. It also makes mechanical excavation more dangerous because shifted pipes and cables are not where you expect them. Hydrovac cuts through expansive clay safely and exposes utilities regardless of how much soil movement has occurred.

A single utility exposure typically takes 30 minutes to two hours, depending on the depth of the utility, soil conditions, and what kind of overburden is above it. Concrete, asphalt, or heavily compacted clay take longer than loose fill. For projects requiring multiple potholes along a corridor, our crew can usually complete 8 to 15 exposure points in a full work day, depending on spacing and conditions.

Yes. We can work with your team to saw-cut or core through pavement and concrete surfaces, then use hydrovac to excavate the soil beneath. This is common for utility verifications at road crossings, parking lots, and sidewalks. The pavement opening is kept as small as possible, and the hole can be patched after the utility is documented.

Unmarked utilities are more common than most people expect, especially in older areas of Dallas-Fort Worth where records are incomplete. Because hydrovac uses water and vacuum rather than a mechanical bucket, encountering an unmarked line does not result in a strike. When we find an unexpected utility, we stop, document it, and notify your project team and the appropriate utility owner so it can be properly recorded before work continues.

In practice, daylighting and potholing describe very similar work, and the terms are often used interchangeably. If there is a distinction, potholing usually refers to a small, targeted excavation at a specific point to verify a single utility. Daylighting can refer to a broader exposure that opens up a longer section of a utility or exposes multiple lines in a single excavation area. Both use the same hydrovac process. Our team will recommend the right approach based on your project requirements.
