What Should You Do Before Concrete Drilling?

You should always consider the first crucial steps before drilling into concrete, no matter the type of project you are working on, such as building or repairing a new shop or a residential neighborhood.

Concrete drilling is hindered by a lot of extraneous objects, like electrical conduits, steel rebar, and PVC or metal pipes and sewer lines. It’s dangerous to drill into these embedded things if they’re not identified beforehand.

Various methods can be used to determine the exact location and what is happening inside drains in order to keep them clean and clear. It is easy to neglect or forget about wastewater pipes and drains because they are hidden. In spite of this, the infrastructures we use every day play an extremely important role.

To maintain a healthy, hygienic environment, drains must be cleaned regularly. Inspecting drains and sewers has never been easier, thanks to modern closed-circuit television video (CCTV) drain survey technology. A CCTV drainage survey is an effective way to ensure no clogs are present in drains and no internal problems exist.

What is a CCTV Drainage Survey?

CCTV pipe inspection cameras mounted on wheels can be lowered and gain access into sewer line pipes instead of digging them or having engineers manually enter them; high-definition images are then displayed on the CCTV camera systems monitor.

From their mobile units, technicians can remotely identify possible problems with pipes using the CCTV video cameras from the CCTV pipe inspection. In addition to rodent infestations and displaced joints that let pests enter drainage systems, these issues can include fissures on sewer lines, worn sections, collapsed sections, pipe blockages, and hairline cracks.

During the analysis, a full drain survey report is provided, along with video footage of the drain system and recommendations as to how the project may be pursued. Suitable for both commercial and residential properties, CCTV sewer inspection can be performed on drains of all diameters.

What is Used in a CCTV Drain Inspection?

Getting a clear picture of the internal components of your drainage system requires various tools and equipment due to its highly technical nature. Tools and equipment for the exercise are typically provided by a leak technician or plumbing professionals. These tools include:

Waterproof CCTV Cameras
Sonar Units
Pipe Rods
Crawlers

Why Perform a CCTV Drain Inspection?

There are several reasons why pipe inspection and analysis should be performed every few months. In the case of a new home purchase, a CCTV drainage survey is usually required.

Homeowners can perform a CCTV sewer inspection to assess the drain system’s condition prior to purchasing a home. If a home needs to be repaired before it can be deemed habitable, the survey can help to identify those repairs.

The pipe inspection should always be conducted by homebuyers when buying residential properties so that they have a full understanding of what they are getting into.

How Does Surface & Concrete Scanning Work?

Ensuring that the concrete surrounding your construction site is safe is critical before you start your next big construction project. Since you might not be able to see underground utilities or confined areas that may be present as well, you may miss them.

If there are things embedded in the concrete, this can be a potentially hazardous, complicated, and expensive project which may even result in accidents. When you can’t see through it, how can you tell if anything is inside? The solution to this problem lies in concrete scanning.

How Does Surface and Concrete Scanning Work

Before coring or drilling concrete slabs or columns, concrete surface scanning is used to inspect them. To provide quick and accurate concrete inspections, Ground Penetrating Radar (GPR) is used.

In both a safe and noninvasive way, GPR can detect embedded objects in the subsurface, whereas X-ray is less accurate in assessing concrete columns, slabs, and walls. It analyzes the subsurface using transmitted waves and their reflected signals.

Scanners can detect hidden objects such as rebar, electrical conduit, post-tension cables, and voids in concrete. As well as concrete slab measurements and rebar spacing, it can be used for structural integrity reviews. Concrete imaging reading can be used if the material is located and its type is determined by an experienced technician.

When to Use Surface and Concrete Scanning

In order to scan concrete, a survey must be completed first. This is something land surveyors typically conduct when discovering new land, but it is just as useful on contemporary job sites.

A survey will reveal the location of utility lines as well as other features beneath the surface that may be hidden. Identifying all uncovered areas allows specialists in ground-penetrating radar to focus their use of concrete scanners where necessary.

How Does Concrete Scanning Help

Surface and concrete scanning contributes to the welfare of the workforce as well as the efficiency of concrete construction, reinforcing steel, installation of utilities, the control of traffic, as well as the repair of underground utilities. Concrete structures are protected from damage when you identify embedded materials with markings in order to reduce the chance of invasive work in these areas.

In the event of a structural failure due to rebar and post-tension cable damage occurs, you risk endangering the lives of employees on site. Electrocution or death can occur if electrical conduits and services are damaged within concrete.

With scanning concrete integrated into your process, you can work more quickly and efficiently while guiding the project’s development. Before any of your workers begin work on their latest job site, you’ll stay under budget and meet the timetables outlined.

Hire Professionals in Your Next Concrete Scanning Project

It is definitely necessary to plan for GPR on the site if an existing concrete structure or utility features are involved, such as concrete floors. In areas with older construction, it’s particularly common to find unmarked utilities when planning the installation, inspection, or repair of subsurface utilities. With GPR onsite, you can avoid these unpleasant surprises.

3 Different Ways for Concrete Imaging and Scanning

If you’re wondering about the safety of drilling into concrete slabs and other structures, what you need to get peace of mind is concrete scanning and imaging. This is a series of non-destructive tests (NDT) for detecting and measuring flaws or imperfections beneath concrete surfaces.

In the past few decades, numerous imaging and scanning technologies have emerged. Before hiring professionals for surface and concrete scanning solutions, you should first gain a deep understanding of those technologies, and the reason why concrete imaging and scanning are important.

Why is Concrete Scanning Important?

There is always the chance of damaging vital infrastructure while cutting, coring, drilling, or sawing existing concrete slabs. This includes embedded materials like communications and electrical conduits, post tension cables, reinforcing steel, void defections, and refrigerant and plumbing piping.

Skipping out on the scanning process could mean project delays, additional costs, and injuries on the job site. Project managers certainly don’t need any added stress, so scanning and imaging services are always a must before starting a construction project.

3 Methods of Concrete Scanning and Imaging

Now that you know how important scanning and utility locating services are, it’s time to dive in on the various methods and scanning equipment.

1. Ground Penetrating Radar

To scan concrete without causing any damage, ground penetrating radar (GPR) is commonly utilized. To detect subsurface objects, the GPR sends out electromagnetic pulses or radar pulses with a very particular core frequency.

The antenna then picks up the waves that have been reflected from underground layers, revealing the buried objects.

Choose Ground Penetrating Radar if you need to:

Find a safe place to drill, cut, or demolish
Locate objects such as post tension cables, rebar, reinforcing steel, and metallic or non-metallic conduits
Measure concrete cover and thickness
Determine the concrete’s internal condition
Uncover defects or voids in concrete

2. Ultrasonic Tomography

This acoustic method efficiently identifies defects in concrete no matter how complex the concrete slab is. This also helps when assessing the thickness and overall strength of concrete structures. It does it through transmitters that send pulses into test objects.

Any reflected signals indicate the presence of defects or interfaces. Using a receiving transducer, technicians can keep a close eye on emitted impulses and reflected waves.

Choose Ultrasonic Tomography if you need to:

Precisely measure the thickness of concrete up to 3 feet
Detect any cracks or delamination between the Portland Cement Concrete (PCC) layers
Locate steel reinforcement
Determine deterioration, dowel position, and spalling at PCC joints
Learn about material properties like the diagnostics of PCC strengths and asphalt compaction levels

3. Radiography Via X-Ray

X-ray scanning may appear to be outdated technology. Nonetheless, it is dependable in terms of providing a clear picture of what lies beneath. Because X-rays provide less room for interpretation of results—including the status of rebars, corrosion zones, and other faults—they are sometimes even considered more precise compared to GPR.

Unfortunately, this can also emit harmful radiation, and the process is slower overall, with images having to be produced off-site.

Choose Radiography Via X-Ray if you need to:

Identify where rebars are situated.
Evaluate bar diameter and depth below the surface
Search for cracks, foreign materials, and voids
Locate variations in density or the presence or absence of grouting in post-tension construction
Check welds on pipelines
Inspect steelwork production
Determine the level of internal and external corrosion

What is Concrete Scanning and What Can It Find?

Before a renovation or construction project begins, concrete scanning is essential. This is the process of evaluating concrete slabs or columns before core drilling. Typically, technology like Ground Penetrating Radar (GPR) is used to spot buried and embedded objects. However, this method is ideal because it’s completely safe and nondestructive.

If you think that you need surface and concrete scanning solutions, it’s best to learn about the ins and outs of the process first. Let’s start with what exactly happens during a typical inspection of a concrete slab.

What Happens During Concrete Scanning?

During a concrete scan, a professional will deliver high-frequency electromagnetic waves using GPR technology through your concrete floor or wall.

Another specialist will then come in to interpret the data provided by the scanner. From there, they’ll be able to show you what’s hidden underneath your concrete and where it is exactly.

Types of Concrete Structures that Need to be Scanned

Any concrete surface can and should be scanned before any cutting or drilling is done. Some samples of structures that need to be scanned are provided below.

Slab on grade
Roadways
Bridges
Beams
Decks
Pylons
Walls
Balconies
Encasements
Tunnels
Sidewalks
Columns
Floors
Ceilings

Common Objects Found During Concrete Scanning

A proper concrete scan can uncover a large variety of objects in your chosen area. Below are just a few examples:

Metal rebars and other reinforcing steel members
Post-tension cables
Electrical conduits
Piping
Plastic tubing
Water lines

The Importance of Concrete Inspection

Before you do any work on your concrete like drilling, cutting, or repairing, you must first determine where utilities and reinforcements are located. This will save you time since you won’t have to spend hours looking for a secure area where you can start working on.

Investing in concrete scanning can also guarantee that you’ll be able to cut and drill safely without harming your tools or the materials that are hidden underneath the concrete.

Additionally, the process can help ensure and maintain the structural integrity of a structure’s foundation.

Check out even more benefits of concrete scanning services:

Reduces the possibility of damage to utilities, rebar, post-tension cables, pipes, and conduits
Lowers the risk of personal injury
Prevents costly mid-project repairs
Simplifies drilling, cutting, and coring

How Much Does Concrete Scanning Cost?

Important factors to consider when determining the price of a concrete scan are the location, area size, and the complexity of embedded materials. That said, the cost varies widely from case to case.

Don’t let this discourage you though. Just think of the construction delays, additional costs, and other possible headaches that can be put to rest with a carefully planned and scheduled concrete scan.

3 Underground Utility Locating Equipment You Should Know

Utility locating not only requires years of experience, but you also need the right tools or equipment to do it successfully. This is true whether you’re a beginner or a veteran searching for utility locations before you dig.

While you’ll probably hire professional utility locators to unearth buried utilities for you, it’s still worth learning about the tools they commonly use to detect utility lines. That’s why we’ve broken down the three basic types of utility locating equipment below!

To truly understand what happens during utility location, take the time to read about magnetic locators, pipe locators, and cable locators that utility companies use.

1. Magnetic Locators

Locating a single point, such as a rebar corner pin or a water pipe, is the primary function of a magnetic locator. Its name refers to its ability to detect objects in underground facilities that would attract magnets.

A magnetic locator is sensitive enough to find even a single ferrous object like steel property pins, manhole lids, and water or gas valves. However, magnetic locators are not recommended for locating underground utilities; rather, a pipe and cable locator should be used for this purpose.

2. Pipe Locators

During utility location, detecting buried pipelines can be a real headache when you don’t have a pipe locator. This nifty tool locates pipes by emitting an electromagnetic frequency that travels through the earth.

That frequency would then ricochet off of any pipelines or similar materials that might be buried underneath. The device is usually attached to the main water valve or hydrant and is used to trace water lines before digging or excavation begins.

3. Cable Locators

Similar to a pipe locator in terms of function, a cable locator is a utility device used to pinpoint the exact location of underground cables or signal lines before you dig.

To estimate the location of subsurface lines and cables, the device also emits electromagnetic frequencies. Most cable locators can be utilized for both direct-connect or inductive-coupling approaches.

3 Reasons to Call In Utility Potholing Services

Before an excavation or construction project begins, it is necessary to perform potholing for utilities. Professional utility potholing is a non-destructive method of determining the exact placement of all underground utility lines.

This utility location method is usually carried out by excavating carefully-planned areas around and above utility wires using a portable vacuum excavator that removes dirt and debris. During potholing, utility crews may come across gas, water, electrical, and sewage lines.

Small test holes may also be created in the earth for finding underground utilities like sewer pipes and utility lines. Potholing techniques eliminate risk by informing builders of the precise location of utilities before breaking ground.

Why Do You Need Professional Utility Potholing Services?

To give you a better understanding of potholing services and why you need them, we’ve broken down three benefits below.

1. It Helps Prevent Damages in Utility Lines

While digging, there’s a huge possibility that you may damage underground utilities. That will require a lot of labor and money to fix, not to mention the service outages that will inevitably occur in the digging process. You can be proactive and easily prevent service interruptions through utility potholing and utility maps.

2. It is Required in Many States

Many states prohibit the operation of heavy machinery within a certain distance of buried utility lines. Doing so exposes employees to a multitude of dangers. That is why most businesses must hire utility potholing services before the excavation starts.

3. It Ensures the Safety of Your Business Location

Understanding and maintaining your work site begins with potholing. Whether you’re laying new foundations or rerouting existing utilities and underground lines, you must know how things stand with your underground infrastructure.

Most Popular Potholing Technique

There are two popular potholing methods commonly used in the construction industry.

Hydrovac Excavation

Hydro excavation is the preferred method of many due to its accuracy compared to other methods. This potholing process moves the soil carefully using high-pressure water and a hose. The excavated material is then dumped into a debris tank.

Additionally, hydro vac excavation is advantageous because it uses water, which serves as a non-conductor. This becomes all the more critical when considering the safety of crew members while working with live electrical wires.

Vacuum Excavation

Another method of potholing is vacuum excavation, also known as air excavation. This technique uses a portable and pressurized device that utilizes air to extract soil via high-speed suction. Once the dirt is removed, it is either dried out or stored in a holding tank until it may be reused later.

An excavator’s fuel tank capacity can be anywhere from 100 to 1,200 gallons. Some potholing professionals believe this is the most secure means of excavating near utilities since they use low-pressure air.

Need Reliable Potholing Services For Your Construction Projects?

In every construction project, safety comes first. That’s why before you even think about digging or potholing utilities, you should reach out to Util-Locate first!

Through game-changing technology and years of proven expertise, you won’t be disappointed by our utility potholing services.
