How Our Services Support Each Other

Our team, at Trinity, offers a variety of technical, pipe, and excavation services. It’s one of the many ways we provide a full service to our clients. One may assume that these services are disconnected from each other, but each of Trinity’s services can support each other in different ways. Let’s talk about it.

Utility locating is one of our core services, helping locate all types of underground utilities. Ground penetrating radar, electromagnetic locators, split boxes and other tools might give you the horizontal position of underground utilities, but determining locations of utilities in congested areas may become tricky. That’s where vacuum excavation comes into play. With hydro or air excavation, you can determine the exact locations of utilities, uncovering overlapping utilities without damaging them, helping to turn Quality Level B utility data into Quality Level A utility data. These two services fall together under the larger umbrella defined as “subsurface utility engineering”, consisting of full utility investigations that correlate with existing utility data.

Concrete scanning and core drilling are also two services that support each other. With core drilling, you’re directly drilling into a wall or floor for a rounded hole. This provides a core that can be used for further concrete analysis. However, you don’t want to core directly into rebar or reinforcement under the surface. Concrete scanning can be used to determine if you’re drilling into something that would cause damage to the overall structure.

Video pipe inspection, hydro jetting, and cured-in-place pipe lining are completely different services, but together they can support a larger pipe rehabilitation project. Pipe rehabilitation would start with a baseline video pipe inspection, determining any blockages and damages. Blockages may prevent the video pipe crawler from examining the pipe for the full length of pipe. In this case, hydro jetting can be used to clear out the pipe for further investigations. A post-jetting inspection can provide a better look at any damages that may exist. It may be determined that a pipe can easily be repaired with pipe lining, preventing a full pipe replacement and additional excavation. In this case, our team can reline the pipe using cured-in-place pipe lining. Together, this provides a full rehabilitation of the existing pipe.

Okay, those are the more obvious ways our services support each other. Let’s look at how video pipe inspection and utility locating can also go hand-in-hand. In some cases, sewers may have abandoned laterals, resulting from construction built over existing construction. Damaging a lateral, even an abandoned one, can result in damage to a larger pipe structure and lead to potential inflow and infiltration issues. Locating these laterals may seem a bit trickier, but tools such as electromagnetic locators and ground penetrating radar can locate a lateral launch crawler. A lateral launch crawler is a specialized video pipe inspection crawler that has a camera attached to a cable that can be “launched” to inspect inside lateral pipes. By tracing the crawler, you can detect any laterals that have been abandoned. Video pipe inspections can also determine if cross bores exist, pushing one utility directly through an existing pipe. Knowing these utility conflicts exist can lead to further investigations of existing utilities.
