Cold Weather Digging with Hydro Excavation

daylighting winter months hydrovac services

It is difficult to name disadvantages related to hydro excavation, other than the costs perhaps, which are higher than the costs associated with traditional digging. However, the provided daylighting Denver area benefits are unmatchable.

Just think, for example, about all the mess you typically encounter on a regular excavation site… Or the problems and consequences arising from damaging underground utilities… Or the downtime during the cold season, when the ground is frozen, and excavation projects are on hold…

All these problems and concerns will disappear with hydro excavation. And yes, it is possible to use it for digging even in frozen ground! Traditionally, people used to thaw the soil, using coal and wood. But besides being expensive and potentially dangerous to the environment (fire hazards), this method only works in a reasonably low temperature range). With hydro excavation, things are different. No more extra work is needed to soften the soil, because a hydrovac truck is equipped with water heating systems; hot water will dig easily through frozen earth and ground frost, and you will reduce not just the time and effort required for your project, but also labor and material costs. This digging method is not only convenient, but also 100% eco-friendly.



When to Use Hydro Excavation

when to use hydro excavation services diggingHydro excavation by Hydrodig in Denver is a digging technique that can definitely make jobs faster, safer and considerably more efficient. This way, a company can cast a wider net for project opportunities, even when it does not have the manpower, because hydro excavation replaces manpower axs well as a lot of support vehicles.

Nowadays, hydro excavation is the most effective and the safest type of excavation and it can be used for various types of digging projects:


You will feel the benefits of hydro excavation especially when you have to perform large scale digging; a hydro truck will make things incredibly easy, allowing you to safely open up the ground in no time.

Remote Digging

Sometimes a digging project encounters obstacles, i.e. places that are hard to reach, digging in frozen ground etc. Using hydro excavation ensures precision handling and high psi, which will allow you to be able to move through anything.


This operation requires a lot of precision, and a hydro truck will do it better than a few shovels and hard hats any day!

Debris removal

Any digging project involves large amounts of debris. With a hydro truck, you will not have to worry about disposing it ensure a safe working site; it will be broken down into smaller parts, and disposed safely and quickly.



How to Choose the Right Hydrovac Company for Your Project

why choose us hydrovac services

Hydrovac, also known as hydro excavation, is the technology used for digging trenches and for moving soil in a safe and efficient way, even in areas that are dangerous or impossible to excavate in because of the existent of underground utilities or for other reasons. There are many companies that offer Dallas hydrovac services – here are some factors to have in mind when hiring one of them for your project:

  • Safety policies – one of the most important features of hydrovac technology is safety, but the operator who handles the powerful hydrovac machine also needs to follow very strict protocols. When you interview a hydrovac company, ask to be shown relevant documents to see how safely the company works;
  • Rates – not all hydrovac companies work for the same rates, so it is a good idea to contact at least three of them to request cost estimates. Evaluate the estimates not only in terms of the total price – consider work quality as well;
  • Experience and reputation – look for a company that has completed several projects of the type that you need hydrovac for and that uses state-of-the-art machinery and check the company’s reputation for reliability, accuracy, punctuality and honesty as well – these qualities are just as important as high-performance machines.

How Does a Hydrovac Truck Work?

how hydrovac does utility digging servicesHydrovac excavation is currently the most efficient and most environment-friendly excavation method, suitable for digging narrow, deep trenches and utility digging as well as for moving earth on large areas and the method is also very energy- and time-efficient. Hydrovac is also considered to be the safest digging method currently available, suitable for excavating in areas that might have unmapped utility lines under the surface and might be risky and dangerous to dig with conventional excavators. Here is how it works:

  • The principle – hydrovac excavation uses pressurized water to move and to break down the soil in the excavation area and powerful vacuum to extract the resulting slurry and to transport it to a large container for depositing. The extracted material is then either redistributed over the land surrounding the extraction area or removed from premises to be safely dumped elsewhere;
  • The equipment – the hydrovac procedure is performed with a special truck that has a part for generating the pressurized water, another one for generating the vacuum and that includes a special container that the vacuum hose is connected to for depositing the slurry;
  • Performance – hydrovac machines significantly shorten the excavation time, being able to perform digging that would take days in a matter of hours.

How Does Hydro Excavation Work

know how excavation works hydro technologyHydro excavation is a technique that becomes more popular by the day, due to its significant advantages: it is safe for the workers, the underground utilities and the environment, as well as very efficient.

Unlike traditional excavation, hydro excavation is nondestructive, very precise and keeps the work site clean of debris, which ensures more convenience and better safety.

A hydro excavator is a large industrial truck with incorporated technology based on pressurized water and vacuum. It can break any type of soil, including frozen soil and can dig up through permafrost as well, because the water can be heated. The vacuum is used for sucking up debris and transferring it to the truck, until being disposed at the designated area.

The water hose and vacuum work together to dig precise holes, trenches, uncover underground utilities etc. It is a fast and reliable method, as well as elegant, at least compared to the highly invasive traditional digging solutions.

It is more expensive than traditional digging, but considering all the advantages it provides, hydro excavation reduces significantly time and labor costs, not to mention that it minimizes accidents on the job site, which otherwise would generate downtime and financial losses.  Look locally for more information


Hydro Excavation vs Air Excavation

Hydro and air excavations are generically known as vacuum excavation. This type of excavation is safe, minimally invasive, but highly effective and has a wide range of applications: construction projects, locating underground utilities, drilling etc. But which version is better: air or hydro vacuum excavation?

When it comes to the operating principle, both techniques involve breaking the soil and sucking it up into the tank to clean the area. The difference is in the way the soil is broke. Hydro excavation uses high pressure water, while air excavation uses pressurized air. Both methods are safe for underground utilities, the environment in general and for the workers, but in certain circumstances, one of the methods can have better results than the other.

There are different opinions on this question, but specialists generally agree on the following aspects:

  • Digging near underground electrical wires is safer with air excavation, because air is not a conductor.
  • There are also areas where water may cause chemical reactions; in this case, air excavation is better once again.
  • Hydro excavation, on the other hand, moves more material faster and can break even rocky and frozen soil, as well as permafrost.
  • When it comes to site impact, both excavation options are safe, but water excavation is better when blasting sand could cause damage in the immediate area.  Check out hydrovac services at

Is Hydro Excavation Safe for the Environment

One of the very efficient and popular digging methods nowadays, especially when it comes to underground infrastructure, is hydro excavation. Hydro excavation is synonym with safe digging, because it will not damage underground utilities. Besides, it is also very efficient and precise.

A professional Dallas Hydrovac services team can handle any digging project you need.

But there is another advantage that you may not know about: this technique is environmentally-friendly, mainly because uses no toxic substances and the digging equipment does not damage plant or tree roots. Unlike heavy oil-based machinery, this process simply uses water under pressure and that is why it is used successfully in construction and landscaping projects. The fact that it prevents the destruction of underground utilities ensures that no harmful substances will leak into the soil and have negative effects on the environments in the long run.

Experienced hydro excavation teams take all the measures to ensure the best environmental practices and ensure that you will have nothing to worry about in the long run.

Hydro excavation can make any digging process clean, safe  and elegant, so once you try it, you will probably never need a traditional digging service again.



What Is a Vacuum Truck

excavation hydrovac digging pipelines

Vacuum trucks (vacuum tankers) are those large industrial trucks, equipped with tanks, pumps and hoses for suction. They are used by cities or businesses for sewer and septic system maintenance, but also for hydro-excavation and other drilling and debris cleaning jobs. They can handle cleaning large-scale liquid and sludge, so they provide a vital service to industries and cities that require environmental cleanup, waste management or storage tank upkeep.

A hydrovac truck is designed to last and work similarly to a shop vac. A pump removes air and creates a vacuum inside the tank, while the pressure will be equalized inside by opening shutoff valves, which will allow the truck to suck up liquids.

Vacuum trucks are essential in environmental disasters that involve hazardous waste that may enter local waterways or contaminating the environment in other ways. They are also used for particular rescue missions, when pits or trenches collapse on workers, and the soil must be quickly removed from the accident site.

In other words, these big machines can handle really messy jobs, of any size, and they handle them very efficiently and safely for everyone. If your company needs a vacuum tanker, there are cleaning contractors that you can hire.


What Is Potholing for and Why Do You Need It?

Potholing is not discussed often enough, but it is in fact a process that can be extremely useful both in residential and commercial building projects. Whether you want to have a new house built, or you’re planning to have a large new office building erected in the middle of your city’s downtown area, potholing will be extremely helpful in determining and avoiding the location of underground utility lines that may be running underneath your property.


The process is simple: you call 811, and if the utility experts are unable to determine where the utility lines actually go, rather than giving you the all clear and risking that your digging and building practices might damage them, they will use potholing as a process to gain visual confirmation of the presence of the utility lines in question.


The actual procedure involves drilling a small hole with the use of a non-invasive digging or drilling process – such as hydro excavation – and using that hole to get a visual of any underground pipes or wires that might be present there. If the location of the utility lines doesn’t match up with what you have on your property’s maps and blueprints, then additional potholing and vacuum excavation services evaluations might be required to remap the utility line network before you get permission to commence your construction activities.

How Can You Really Decide Between Air and Hydro Excavation?

Water Excavation Vs AirAccording to some, air and hydro excavation are equally good when it comes to drilling holes and digging trenches that will be used as part of a future  construction project. However, many water excavation experts actually affirm that hydro excavation is superior, for a number of reasons.


First of all, hydro excavation involves a greater amount of pressure and weight that can break through harder surfaces. As a result, it is typically better when dealing with hardened or cold surfaces that require a more “full force” approach.


Hydro excavation is also cleaner and more efficient. Many consider it to be faster, and the risk of damaging certain utility lines is also lower due to the less explosive interaction between high pressure water and your soil. This also means that fragile tree roots will be better protected when you use a hydro excavation method, as opposed to air excavation.


Although the question of whether hydro excavation is actually a better process than air excavation, this issue is far from being resolved, and the fact remains that in some particular cases, air excavation is actually preferred. To determine whether your construction needs will entail hydro or air excavation, consider calling your local excavation professionals and asking them to evaluate your property to give you a final answer.
