Lessen the Surface Damage during Your Excavation Project—Here’s How!

Util Locate At Work

When you are managing or working on a construction project, there are a lot of important factors to keep track of, such as budget, time constraints, and crew management. Modern construction sites have the advantage of using new equipment and methods that make work more efficient and less strenuous on your workers.

One common concern on many construction sites is the question of how to minimize surface damage when carrying out necessary work like utility excavation. Other methods of excavation involve imprecise equipment that has to tear through the ground to reach the utilities. This is why vacuum excavation is so important for any modern construction project. 

Our expert team has years of experience with utility potholing and ensures that only the most minimal surface disruption occurs. This creates a more seamless process from potholing to post-excavation work. You will not have to worry about restoring the ground to its original state, which will save you both time and money—precious resources on any construction site!

Keep reading to find out the various ways you can limit the surface damage while excavating your construction site.

Plan Ahead

The way you prepare for excavating your construction site can be the difference between disaster and success. To make sure you collect all the necessary information about your construction site and the terrain, you should do the following:

 

  • Check the maps: before you break ground on your construction site, you should consult approved utility maps, which Util-locate can provide to you alongside our other excavation services. These maps will show the location of subsurface objects such as pipes and cables as well as sewers, gas, and electrical lines, which you will need to avoid striking. 

Referring to utility maps will get your project off on the right foot because you will be better informed and more aware of where to excavate for visual confirmation. Utility maps are a simple way to reduce the amount of earth that needs to be disturbed so there is less surface damage overall.

 

  • Look at the surrounding area: the area around your construction site will inform you about how to proceed and will affect your budget. For instance, you will need to know where the nearest water supply and dumpsite is. A reliable water source is needed for the efficiency of hydro vacuum excavation and the proximity of a dumpsite will reduce the time spent driving unwanted soil away from your construction site.

  • Consider using RADAR first: as with utility maps, RADAR technology is an important part of pre-excavation preparation. Ground Penetrating RADAR (GPR) is a non-intrusive surveying technique, which is used to locate utilities, rebar, conduits, voids, and other features below the surface.

Why is this useful? Because it records subsurface data, which can inform our specialists about how deep your excavation holes will need to be. GPR is completely non-destructive, which means it will not cause any surface damage. 

GPR can be used on all types of surface because it can penetrate through soil, concrete, water, and many other types of terrain. It also detects more than just metallic objects like pipes, it can pick up on the location of other things like fiber-optic cables which are just as important to avoid during excavation.

 

  • Choose a reliable excavation method: the most important thing to do to minimize surface damage is to choose the least invasive excavation method. Most construction sites now opt for hydro vacuum excavation when utility potholing because it is not only the most reliable method, but it is also the safest and most accurate. 

Taken altogether, these features make vacuum excavation the best choice for anyone who wants less surface damage as well as efficient and precise utility locating. 

 

  • Hire a professional team: a team that is highly trained and experienced with vacuum excavation is the only way to make sure the excavation is carried out properly. A professional excavation team will create only the necessary surface disruption, which means you will spend far less time and money resurfacing the construction site after the excavation.

Choose the Least Invasive Methods

As briefly mentioned above, when it comes to utility potholing, the method you choose will affect how much the surface is damaged.

In the past, it was common to excavate by hand or with a backhoe, but both of these methods come with major downsides. Excavating with trowels and shovels is extremely time consuming and labor-intensive. While the initial cost may be cheap, its inefficiency and the number of workers needed to carry out the excavation means that the cost will add up exponentially over time. Backhoes are much more efficient, but the machines used for it are not accurate and utility strikes are much more likely to occur.

Remember: when you strike a utility line, the damage will always need to be repaired. This means even more excavation will be required, in addition to what are usually hefty fines and long delays.

To avoid these issues and unwanted costs, it is always recommended to use hydro vacuum excavation. Not only will you receive visual verification of utility line locations, but it can also be done quickly and safely. When the work is complete, only the small excavation holes will need to be covered over. 

 

Stay Safe

Overall, the safety of your crew is the most important thing. Safety measures and training should always be implemented to ensure that everyone on the construction site can stay safe and injury-free.

Utility strikes can result in the loss of water or energy resources within the local community, which is especially dangerous for buildings such as hospitals. This is why it is so important to choose a method that will keep everyone, including members of the public safe.

When carried out by a professional team, vacuum excavation is proven to be time and cost-efficient, as well as incredibly safe. What is an added bonus is its ability to lessen the surface damage incurred by the excavation process.

5 Things to Expect from Professional Vacuum Excavation

hydro vacuum excavation

When managing a construction site, there’s a good chance that you will need to locate underground utility lines. A big decision to make is which construction method to use to locate these lines. From backhoes to utility potholing, there are a lot of utility locating services out there. 

By far, the most precise method is hydro vacuum excavation. This method is far less invasive than others and uses water pressure to clear away the earth from the utility lines. Not only is this process incredibly accurate, but it is also efficient and cost-effective.

What Can You Expect from Professional Vacuum Excavation?

1 – Efficiency

Time is money, and this is especially true on a construction site. Project timelines have to be met, and potholing utilities can help make this happen.

While some people opt to dig for utility lines by hand because it is a cheap option, it is so time-consuming and labor-intensive that it can actually be more costly in the long run.

Backhoes are another common method used and are certainly efficient. However, the wayward nature of a backhoe can make them difficult to use, which means a utility strike is more likely. When a utility line is struck, it can result in delays while repairs are being carried out.

These are just a few reasons why vacuum excavation is so time-efficient. With a highly-trained team, vacuum excavation takes less time without the risk of a utility line strike or other damage to the construction site. And because less earth is displaced during the process, you can continue other construction work nearby.

2 – Safety

The safety of your workers and the public is of the utmost importance for any construction project. You can expect that our experienced team will keep your construction site safe while carrying out the vacuum excavation.

While you could buy or rent the vacuum excavation equipment, if your team is not adequately trained, it can lead to damage to either the utility lines or the equipment itself. You might also be putting your team at risk, which should never happen.

A utility strike can also cause the surrounding community to lose power. That means important public facilities like hospitals, schools, and police departments won’t be able to function properly. Your construction site will be liable for this disruption and damage, which can mean hefty fines.

Instead of risking it, hire a trained team with years of experience who will quickly and safely excavate your utilities.

3 – Expertise

When you hire a team to carry out hydro vacuum excavation, you can expect them to be highly trained and fully qualified for this work. This is so important when you consider the many risks involved when locating utilities.

The Util-locate team uses a variety of methods and techniques to provide you with the most stress-free and efficient experience. Vacuum excavation is so accurate because it offers visual confirmation of where the utility lines are.

However, before this even happens, you can also take advantage of our utility mapping services. Detailed and accurate maps show everything that might be hiding under the surface: storm drains, gas, water, reclaim, communication, electrical, abandoned, and unknown lines or objects.

Once you have access to a utility map, you can also use Ground Penetration Radar (GPR). GPR uses pulses of energy to provide an impression of where utility lines are located.

Following these techniques, it is still recommended that you carry out vacuum excavation. Visual confirmation will ensure that you know exactly where the utility lines are and removes all risk of accidentally striking a utility line.

4 – Precision 

One of the best things you can expect from vacuum excavation is a precise and thorough service. When potholing for utilities, accuracy is the primary and most important goal. You want to confirm exactly where the utility lines are located, and this is only possible through methods of excavation.

As we’ve already discussed, other forms of excavation like backhoes or manual excavation might reveal where the utilities are, but they can be costly and end up damaging the utility lines in the process.

An experienced team will offer you a variety of utility location services. That means accurate mapping, RADAR technology, and hydro vacuum excavation are made available for your construction project.

Hydro vacuum excavation is especially useful because of how it displaces the excavated earth. Typically the earth will be removed into a special container, making removal and disposal a simple and easy process.

5 – Cost-Efficiency

Of course, it is only natural to want to keep costs down so that your construction project can adhere to the projected budget. Vacuum excavation is a great way to prevent unexpected costs that could arise from a utility strike. 

There is a good chance that if you damage a utility line, you will either be fined by the local authority or have to pay for extensive and pricey repairs. Costs like this aren’t always factored into the budget for smaller construction projects and can cause serious financial burden and stress.

Utility potholing is also very efficient, which means an estimated timeline for the work is usually very accurate. You won’t have to worry about renting the equipment and hiring a team for longer than expected, saving you both time and money. What’s more, you can continue other construction jobs alongside the excavation so that more work gets done.

The Bottom Line

Potholing for utilities has been proven to be the most accurate method of utility locating. When hiring a professional team, you can expect the process to be straightforward and pain-free. The work will be done efficiently, accurately, and safely, which means your construction project will save both time and money by investing in vacuum excavation.

Compared with most excavation methods used on construction sites, vacuum excavation is still a fairly new tool used for easy utility potholing and accurate excavation. Instead of manual tools or unwieldy equipment, vacuum excavators use a hydro or air jet to gently blow pressurized water or air into the ground to clear away earth. This process is more accurate than other methods and there is little risk of damaging utility lines.

Keep reading to better understand how Vacuum excavation works. This article will explain the process, necessary safety measures, and the many benefits of choosing vacuum excavation over manual digging or backhoes.

What is Vacuum Excavation?

In recent years, vacuum excavation has become the go-to option on construction sites for efficient and thorough excavation. Excavation is an important part of most construction projects because it allows you to understand what is going on underneath the earth. That means being aware of all utility lines, like water or gas, as well as any underground structures that might be in place.

Some methods of excavation, like backhoes, are too cumbersome to carefully excavate the land without risking damage to these utility lines. Such damage can be extremely expensive to repair and if the construction site is in an urban area, the damage could affect the surrounding area. This could lead to extensive fines for affecting the community in an adverse way, such as shutting off the power at a hospital or school.

Understanding the full extent of the risks involved in utility potholing should make it obvious why vacuum excavation is such a good option.

Vacuum excavation technology allows a professional team to gently remove earth from the construction site to reveal a completely accurate image of where the utility lines are located without any risk involved. Not only is the process effective, but a well-trained team can excavate the site quickly without sacrificing thoroughness.

Vacuum excavation can handle nearly all types of terrain: clay, dirt, rough and rocky soil are no match for this equipment. Whereas other forms of excavation can struggle to carefully remove rocky terrain, the water or air pressure from vacuum excavators remains an effective and quick option.

While hydro and air jets work in very similar ways, some will opt for air jets because the earth that is excavated can be reused at a later time. This is not possible with the earth that is cleared using water, so it is best to consult with your team before deciding which type of vacuum excavator to use.

Safety Measures

As with all tools and machinery on construction sites, vacuum excavation should only be carried out by a highly trained individual or team.

The most cost-effective option is to hire a vacuum excavation specialist who can complete the work with ease. Renting the equipment and training someone on site is not only more expensive but can also cause delays for the construction project or cause damage to the machinery or construction site.

To prevent these unnecessary expenses, opt for a team like that at Util-Locate who have years of experience and can understand the needs and scope of your project. 

Benefits of Choosing Vacuum Excavation

To better understand the benefits of vacuum excavation, you should consider the downsides of its alternatives: backhoes and hand excavation.

As mentioned above, backhoes are an unwieldy piece of construction machinery, which lack the finesse of a vacuum excavator. While the job might get done quickly, utility lines could be struck or ruptured in the process. We already know that this can result in fines, but you could also have to push back the deadline of the project due to the need for lengthy repairs before construction work can be continued.

Smaller sites have previously relied on excavation being carried out by hand with the use of shovels or trowels. While there is certainly less risk of rupturing a utility line, this method is very time consuming and will result in overworked and exhausted workers.

Due to the amount of time this form of excavation takes, it is not as cost-effective as you might assume. You might save money on equipment, but this is canceled out by how long the process takes and the number of workers it will require.

You might also have heard of RADAR technology, which uses radio waves to locate utility lines. While this might seem like a great option because it limits the need for physical excavation, it is not 100% accurate. This discrepancy in accuracy means utility line ruptures can still occur. If you use RADAR, it should be used alongside a vacuum excavator. Doing so will maximize accuracy while limiting the area you have to excavate.

So, it is easy to see why vacuum excavation for utility locating and potholing is such a good option. Not only will it preserve the integrity of the construction site, but you will save money and time.

To conclude, it is essential for the safety and success of your construction project to choose an excavation method that is both accurate and efficient. Vacuum excavation is proven to be the most accurate method for construction site excavation and a professional team will ensure that the work is carried out according to your team’s needs.

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. See more about potholing excavation.

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.

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 oder 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

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.

utility potholing

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

utility potholing services

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.

utility potholing

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. See more about vacuum digging.

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.
