Avoid Excavation Hazards and Utility Strikes, Call the Potholing Experts

It is well known that construction sites are inherently dangerous and there are a lot of risks that go along with excavating earth. Although it is tempting to choose the cheapest or least time-consuming option to get the job done, such choices can lead to expensive disasters down the line. Utility potholing uses vacuum excavation technology in order to carefully and efficiently locate all underground utility lines without damaging them.

Utility potholing is an excellent option for most construction projects and will likely save you and your crew both time and money. Using a professional team will ensure that your construction site is excavated properly and as quickly as possible. While potholing is an investment, it will ensure that you avoid extensive damage and expensive repairs or fines.

Keep reading to learn how vacuum excavation can help your construction project run smoothly without the risk of utility strikes.

Other Tools Don’t Cut It

When you compare potholing to the other tools available, it becomes quickly obvious that professional potholing is the best choice.

Those with smaller construction sites often think that excavating the land by hand is the best option because it is so inexpensive. However, digging with hand tools like shovels and trowels requires grueling physical labor. Depending on the site, it can also take many days to complete. The contractor might want the work completed by a certain deadline and it just isn’t possible to know exactly how long excavating by hand will take.

While hand tools might not cause damage to utility lines, it isn’t recommended that you use this time-intensive and exhausting method.

Meanwhile, you might also consider renting a backhoe because they are generally considered an affordable and efficient method. However, it is incredibly difficult to use finesse with a backhoe, which means there is a much greater chance of striking a utility line. This is a fine option if you are certain there are no live utility lines under the land but should be avoided otherwise.

If you do opt for a backhoe, remember to employ an experienced spotter who will help guide the equipment and avoid utility lines. Even so, the risk to utility lines is far greater than it would be with vacuum excavation.

How Potholing Works

Potholing works to carefully excavate a construction site through the use of air or water pressure.

Air or water is gently, but firmly, push through the earth so that the locations of utility lines can be discovered without physically touching them. Even better, the use of an air jet allows the earth to be stored and reused at a later time in the construction process. While this cannot be done with a hydro jet, both are great options for keeping your construction site safe.

Potholing is an effective method that involves clearing the earth away from utility lines. It is also time-efficient and cost-effective. When used properly, vacuum excavation is the best method available for any construction project.

Safety Precautions

As with any construction equipment or machinery, safety measures must be taken to ensure the well-being of your crew.

You will still need to plan ahead of time to fully understand how to vacuum excavate the property. For instance, you should call all relevant third parties who have knowledge of the construction site. These third parties may have information concerning utility lines, which will assist you during the excavation.

It is always safer to choose a professional, experienced team. These professionals understand the delicate excavation process and will be much faster and more skilled than an untrained worker.

A professional team will also understand the importance of inspecting the area beforehand. This involves creating a small hole through which the professional can explore the underground area. RADAR or digital technology doesn’t compare to visual verification of what is underground. Damage to underground utilities can result in unexpected expenses from repairs or fines.

Usually, these fines occur if the damage disrupts access to utilities for those living and working in the surrounding area. It is important to respect the local community and do everything possible to ensure the construction is safe and takes necessary precautions.

When in Doubt, Seek Help

If you are in doubt about how to excavate your construction site, it is advised that you choose potholing. Vacuum excavation is an advanced technique that, when carried out by an expert, is both safe and efficient.

By opting for potholing, you avoid the risk of striking a utility line, which could severely impact the overall success of the construction project.

Not only will a professional team be able to understand the needs of your project, but they will carry out the work without putting workers’ health and well-being at risk, as well as protecting the land itself.

Never Just Dig Holes Again! Let the Pros Pothole Your Utilities 

utility potholing

When you are planning to carry out excavation work for a construction project, utility potholing is an absolute necessity.

If you aren’t already familiar with utility potholing, it’s a construction method that allows a crew to investigate underground and find any potential water or sewer lines. Professional utility potholing companies have specialized equipment that isn’t affordable to rent for a short term job. Typically, companies use a hydro or air jet, which gently vacuum excavates the site so that underground pipes are easily located.

You might think that using RADAR technology or ordinary hand tools would be as effective, but these techniques are in fact far less accurate. Making a mistake and damaging underground utilities on a construction site can lead to expensive, extensive, and time-consuming repairs. Utility potholing prevents these steep costs and will give you peace of mind throughout the process.

The Problem with Traditional Tools

Even if it is a small scale construction project, excavating by hand with a shovel or trowel is labor-intensive and exhausting. Hand tools are arguably useful for getting into small spaces and are certainly affordable. However, costs can pile up depending on how long the excavation drags on. Added to this, the individual and company you contracted the work might be on a tight schedule and not want to wait for the work to be done by hand.

Hand tools can also make the work more difficult depending on the terrain. Clay, rough terrain, or especially rocky land can cause all sorts of issues and delays.

Another option many people consider using are backhoes, but it’s important to remember that they should only be relied on when you aren’t worried about what’s under the construction site. So if you’re okay with tearing up an existing site, backhoes might work out fine because the job can be completed quickly.

Just bear in mind that utilities will be at risk when a backhoe is used. A spotter on the ground can only do so much and mistakes can happen in even the most careful construction zones.

Why Choose Utilities Potholing?

As mentioned before, when done by a professional, utility potholing is an accurate and effective tool to locate underground utility lines. Here are a few of its benefits:

Minimizes damage

The tools used are gentle enough to clear away earth without damaging the lines you are trying to locate. When compared with other tools, it’s the most accurate way to find the location of water or sewage lines.

There are two types of potholing: air and hydro excavation. Both are very effective techniques and surprisingly cost-effective despite the investment in machinery.

Air or pneumatic excavation uses compressed air to displace soil and unearth the utilities that lie beneath. One benefit of using air excavation is that the soil can be reused at a later point to fill in any holes that were left behind by the excavation.

On the other hand, hydro excavation uses pressurized water to remove the soil by turning it into wet slurry and vacuuming it away. Unlike in air excavation, the wet soil can no longer be reused to refill the hole later on. Nevertheless, hydro excavation is still the most used method of utility potholing today.

Reduces surface damage

Another type of damage you might not have considered is surface damage. With air or hydro excavation, the actual construction site will remain relatively untouched until the real work begins. 

With traditional tools, large amounts of earth and removed from the site and relocated, which is neither time nor space-efficient.

Increases safety

A final benefit is how safe utility potholing is. When a water line is severely damaged, workers can get injured and anyone living or operating a business in the surrounding area can be seriously affected.

Causing that sort of damage cannot be taken lightly because you could be held liable for the costs and inconveniences experienced by anyone affected. So not only will you have to pay to repair the damaged lines, which is expensive in itself, but you could have to manage lawsuits and fines as well.

Tips for Professional Utility Potholing

While utility potholing is generally a far safer and quicker process than other excavation methods, there are still some precautions and techniques that should be used by professionals to ensure the process runs safely and smoothly.

Extensive planning: Before any excavation takes place, you should plan ahead. That means contacting third-parties about any cabling that might be underground. You should aim to be as precise as possible to avoid expensive damage to cables. Damaging infrastructure below the ground is one of the easiest ways to incur delays and extra expenses.

Safety is a priority: It might seem unnecessary to hire a private excavation company, but professionals are trained and highly skilled individuals. Hydro and air excavation require this level of skill and leaving it up to a professional will avoid mistakes and mishaps. Professionals are also accustomed to working on complex sites and will keep the machinery away from any overhead wires, which someone less experienced might forget about.

The Bottom Line

Vacuum excavation for utilities is one of the most sophisticated methods for exposing underground utilities. It’s safer and more effective than most alternatives, and it can be far more affordable in the long run. While it is a large upfront investment in a professional team and equipment, this investment ensures that you avoid serious damage to the construction site and hefty expenses down the line.

If you want a safer and more efficient experience on your construction project, choose a professional team to pothole your utilities.

Hiring Vacuum Excavation Experts Prevents Accidents

When planning your next home improvement or repair project, make sure to proceed with caution. This is especially true if your project involves digging. The first step to any project of this magnitude is having a proper utility locate service performed. While it may add a few days to your project’s timeline, having utility potholing completed in your yard can save you from dangerous outcomes.

What Went Wrong in Southern California  

Recently, Southern California was devastated by an accidental gas explosion: fifteen people were injured, and a Southern California Gas Company worker lost his life. Sadly, the ruptured gas line could have been avoided had the local contractor used a utility locating service. 

The contractor not only violated state law but put others at risk. Most likely, the contractor didn’t think locating utilities was essential for the work he was doing. It’s far too common for contractors, handymen, and homeowners to either be overconfident in their abilities or to underestimate the task at hand. However, one must always consider the dangers of their projects and determine whether or not the are truly qualified.

Accidents involving utilities do not always result in death. Some accidents result in damaged property, physical injuries, or high costs. In some cases, calling the local utility company might suffice. 

In other situations, it’s best to hire a private utility locating company. These private companies often have more autonomy on your property and can identify all of your utility lines in one visit.

Experts Always Do a Utility Pothole Inspection

Potholing is a process that confirms underground utilities and obstructions. As the first part of investigating what’s underground, utility potholing starts with a small, exploratory hole along the planned route of new construction or repairs. While some contractors rely on digital locating devices to find pipes, utility lines, and other obstructions, there are times when actually seeing what’s underground is essential.

Digging without first locating underground utilities runs the risk of hitting the gas, power lines, communications, water, and sewer lines. While nicking one of these utilities might seem harmless, it can result in significant issues: 

  • Service disruption
  • Costly repairs
  • Acute injuries
  • Death

Did you know? Accidentally cutting an underground fiber optics line could stop internet services from working throughout your neighborhood, and you could be held liable for the loss of that service.

What Methods Do Excavation Experts Use?

In the past, manually removing dirt was the only method used to locate and protect utility lines. There are still times when hand tools are preferred. Modern techniques include vacuum excavation. The best method depends on your project and what gets the job done.

Hand Tools

While labor-intensive, using a shovel, pickax, or another hand tool to pothole is perfect for small spaces where precision is necessary. Hand tools are also the cheapest pieces of equipment used to dig. On the flip side, hand tools require a great deal of time and effort, especially when dealing with harder ground surfaces. Shovels are unlikely to damage underground pipes but can slice through cable or communication wires.


When precision isn’t necessary, backhoes are incredible options. The work is much less labor-intensive and can be completed rather quickly. When a new development is excavating for new foundations, backhoes are the easiest and best option. The biggest downside of using a backhoe exists when utilities are present. 

Even the most skilled backhoe operator runs the risk of hitting and damaging subterranean lines. This is why most backhoe operators use a spotter to help keep a closer eye on where they are digging. Backhoes also don’t fit into many spaces, especially once houses or other structures are in place.

Vacuum Excavation

Simply knowing where a utility line isn’t always enough. Many projects need to work around existing utility lines. Digging up an entire utility line can take a long time, cost a lot of money, and require quite a bit of workforce. Also, you must consider how digging can destroy your yard. 

Vacuum excavation is a method used to locate underground utilities without the same mess as manually digging. The process involves using water or air to break up soil before suctioning up the broken ground into a storage tank. Vacuum excavation contractors can eliminate nearly all risk of damaging underground utilities at a lower cost and higher level of precision. In some cases, the soil can even be reused cutting down on landscaping costs.

There are two main methods of vacuum excavation:

  • Air Excavation:

Air excavation uses compressed air to loosen and break up the soil. Since the primary element of this process is air, the earth is still used to fill in holes later on.

  • Hydro Excavation:

Instead of air, hydro excavation uses high-pressure water to loosen and break apart dirt. This technique is also extremely precise, although faster than air-based methods. Since the primary element is water, the soil is no longer fit to be used again.

Both air and hydro excavation allow you to pothole quickly, easily, and safely. At the same time, however, the vacuum excavation process is not something anyone can do. Besides the hefty investment in equipment, operating a vacuum excavation system requires a great deal of skill and experience. 

Unfortunately, your utility company or other public “call before you dig” service most likely won’t use vacuum excavation methods. Hiring a private potholing company may seem like an extra expense, but it can certainly save you money in the long run.

Which Method is Best?

The nature of the job at hand will ultimately determine which method is best. The key is that underground utilities are safely located and protected to keep major accidents from becoming commonplace. 

Most homeowners won’t be able to decide on their own which method is best. Using a reputable utility locating company is the best way to ensure your project or repair is done without the risk of a significant accident.

Vacuum Excavation VS. Traditional Excavation Techniques

If you are planning a home improvement project that involves digging into the ground, you’ll need to start by having all underground utility lines found. Even small projects like adding landscaping or installing a new mailbox require the use of a potholing company. These companies use a variety of techniques to locate and protect utilities. From backhoes to hand tools, and vacuum excavation, here is what you need to know about the type of methods.


Backhoes are most often used when precision isn’t as important. For example, when a new development is digging up the foundation for new homes. It involves much less intensive work than other methods and can be completed rather quickly. When used for potholing, backhoe operators rely on a spotter who helps keep an eye on the ground. 

The downside to using a backhoe is that there is an additional risk when utilities are present. Even a skilled operator runs the risk of hitting and damaging the very line they were trying to locate. Due to their size, backhoes might not fit into many spaces, especially once houses are in place.

Hand Tools

Using a shovel or other hand tool to pothole is the most labor-intensive for the individual. Because the equipment needs are small, operators can get into almost any space. Outside of the necessary working hours required to dig, hand tools are also the lowest priced option. 

The major downside to using a shovel is the labor involved. Digging, especially on rough terrain, can be tough work and take a long time. While hand tools are relatively safe for locating utilities, caution is still required. A shovel probably won’t do any damage to an underground pipe, but it can sever fiber optics or other wires.

Vacuum Excavation

Utility locating is the first part of the investigation process. You need to know where utilities are before continuing. Then, using vacuum excavation, you can verify the utilities by potholing, or exposing them for visual identification. 

Vacuum excavation is a process where water or air is used to break up soil before sucking it up into a storage tank. This process eliminates nearly all risk of damaging underground utilities. It offers a lower cost, outside of the initial equipment investment, and a higher level of precision.

  1. Air Excavation: By using compressed air, this method loosens the soil to be stored in the tank. Since it’s only using air, the ground can easily be reused to fill in the holes later on.
  2. Hydro Excavation: Instead of air, this method uses pressurized water to loosen dirt. This technique is extremely precise and much faster than air-based methods. It does not, however, allow the same soil to be reused.

Which Method is Right for You?

Ultimately, the method used is going to be determined by the nature of the job. It may not be easy to decide on your own; using a reputable utility locating company is vital. You might be tempted to try a digital meter or to call your utility company. 

Unfortunately, utility companies often won’t come on to private property. When they do mark underground obstructions, it’s typically with spray paint. A digital meter is also useful to simply mark the surface. Many jobs require seeing the actual obstacle and not just relying on a rough estimate of where it is. Using a private utility locating service will ensure your job is done safely and without the delay and cost associated with damaging utilities. 

Utility Potholing & Vacuum Excavation for Your Underground Work

The value of precision in any construction project is hard to overstate. If the technology age has taught us anything, it is the value of miniaturization, precise tolerances, and optimizing the process of building a solid foundation for future improvement.

The high-tech environment comes with its share of challenges, however. Beneath our feet is a maze of electrical connections, gas lines, sewer, and water lines and data cables. It seems every building has its own collection of interfaces to city and county facilities. Things are only going to get more complex as time goes on. Construction crews, contractors, and even utility workers can’t afford to make mistakes when it comes to surveying a site for repairs, new construction, or simple maintenance checks.

The solution is to find a company with the experience and the tools to make vacuum excavation and utility potholing simple, quick and effective.

Keeping It Simple

Vacuum excavation services relies on what would seem to be the simplest of principles. Dirt and debris are mixed with water, liquified, and extracted with a high-powered vacuum. It is what regulators call a “non-destructive” process. This new and effective means of removing dirt and rocks from around sensitive underground facilities is now required by some states when crews are digging near safe zones.

Once the underground work is complete, the dirt is replaced by merely reversing the pressure. In the interim, the liquified material is stored in a tank on site. As an added bonus, since the material is already liquified, when it is replaced it “sets” very much like cement. There is often little evidence any digging ever took place.

Safety First

Imagine you are building on a site with pre-installed utilities. You have a backhoe in operation. This means digging at the site without sufficient information or worse, outdated information about what kinds of utility lines are present and where they are located. The backhoe blade strikes a gas line. There is a spark.

This is the kind of situation vacuum excavation, and potholing is meant to prevent. It is necessary to know the precise whereabouts of utility lines. It is also vital to understand the nature of those lines and what they might present in terms of hazards. Safety is always of utmost concern at a job site. The crews are at risk, and so is utility service to the surrounding neighborhoods and region.

Digging precisely and with the right tools and process allows you to know with specificity before you engage in large-scale digging or construction. Making the wrong decision or being in too big a hurry carries with it risks no construction crew should have to face.

The Right Team

It is in every stakeholder’s best interest to have experts in their field doing the work they were trained to do. This is why you need an experienced and knowledgeable team at your construction site to find the utility lines before your crew accidentally damages them. It is better and safer for everyone involved, and in the long run, it will save you time and money.

Vacuum Excavation: Achieve Less Surface Damage

Surveying a construction site is not only a necessity; it is an accepted and recommended practice for several reasons. Among the most urgent is the safety of the construction workers, along with the integrity of the structure and works built at the location. Also high on the priority list is keeping the grounds intact and free from unnecessary damage or navigational hazards.

Excavation is one of the most expensive things a construction company can do. Moving tons of earth from one place to the next is a non-trivial undertaking. What’s more, leaving deep holes, trenches, and other impassable obstacles behind can be a major safety hazard to say nothing of their effect on future building. The good news is there has been a better way to do things available to contractors for some time. It’s called vacuum excavation. If you haven’t taken advantage of it yet, you will be quite surprised at what it can help you accomplish.

What is Potholing?

Suppose you need to dig at a construction site to determine if there are any hidden underground hazards, pipes, electrical lines or other obstacles. What is the better option?

  1. Breaking out the shovels and pickaxes and hoping you don’t break something as you descend into the darkness


  1. Using a high-tech method that allows you to simply remove dirt and rocks and then replace them later

Potholing for Utilities is the second and best method.  It is being used more and more by construction companies and contractors to help locate facilities that might otherwise be damaged if not located beforehand.

Time Savings

Key to any construction project is the ability to save time and expense, both for the contractor and the client. When it comes to safety and the regulatory requirements of checking before digging, anything that increases the efficiency of the process is going to be an obvious priority. This is one of the reasons vacuum excavation services has become so popular so quickly.

The equipment itself is self-contained and operates on the simple principle it is possible to remove mud with a sufficiently strong vacuum and then replace it by reversing the pressure. Since no blades or bits are hitting the ground or anything underneath it, the potential for damage is practically non-existent. Further, once the earth is replaced, the process of drying causes it to set very much like cement, leaving almost no evidence any digging.

Practical Efficiency

Since in some states digging near a marked safe zone is prohibited by regulation, air and hydro excavators have become the go-to tools. These processes are considered “non-destructive” and are therefore recommended to avoid expensive accidents, not to mention the possibility of interrupting local utilities like electricity or water service.

When the possibility of hitting a gas line is taken into consideration, what might once have been a good recommendation becomes a necessity. Vacuum excavation is the correct choice in most construction contracting, and it is a safe choice when it comes to preserving utilities and underground lines.
