GPR Surveys: Learning About this Technology and its Benefits

 New to the term GPR? It might appear as a jargon at first. Until and unless one’s associated with pipe inspection, repair and renovation, it’s hard to figure out the true sense of the term. You must be wondering what made this term the highlight of this blog today. It’s the upside to this technology that inspired us to pen down an entire write-up. If you are here, you shall soon recognise the advances in technology, the depth and greatness of which has led to the evolvement of innovative techniques like the GPR surveys.

An alternative to the conventional system of locating buried utilities, GPR is an improvement over the common drawbacks experienced with its traditional counterpart. It arrives as a boon to the providers of underground pipe repair and renovation services. Let’s check how by starting from a formal introduction to its advantages and applications.

What is GPR?

It’s an acronym depicting Ground Penetration Radar and a geophysical method of investigating utilities like pipes, cables, concrete, metals etc below the ground level. The outcome is an archive of images derived from the interception of radio waves to capture whatever’s lying under the ground.

How does it operate?

Electromagnetic energy is the heart of GPR surveys. With the help of a transmitter, it reaches into the soil and bounces back as echoes after hitting the subsurface objects. The receiving antenna catches them and translates them into images of utilities buried under the ground surface.



What Items does GPR Detect?

The technique is flawless in detecting materials. A wide range of items from metals, PVC, plastic to natural materials and concrete is easily recognisable from a distance with this subsurface tool. This is exactly where it enjoys an upside over the traditional electromagnetic induction utility. While the latter fails to locate plastic conduits and sanitary sewers, GPR does it in the wink of an eye. Not quite literally but supports the detection of both metallic and non-metallic objects in a non-invasive manner.

Advantages of this Technology over the Traditional One

Apart from being cost-effective and non-destructive, the survey enjoys a list of advantages. Let’s check them out to know it better.

ü  Since it’s a non-destructive method that hardly requires excavation to collect information, it’s safe for all project sites and public spaces.

ü  Besides metal and non-metal objects, it detects void and even irregularities.

ü  Conducting it requires little to no hassles as no ground disturbance, digging or excavation is necessary.

ü  It provides in-depth information about the target, including thickness and dimensions.

ü  Collected data can be of immediate use or for future projects.

ü  It’s very much affordable as against the conventional methods.

ü  Its coverage is huge.

ü  Scanning of only one side is enough for data generation.

ü  Efficient in detecting septic tanks and storage tanks as much as leach fields.

Whom to Approach?

Maybe it’s for concrete inspection or utility mapping or for identification of natural obstacles to analyse the risk that convinced you into considering GPR. Who do you think nails the job in Ireland? Though there are plenty to name, very few have the experience to conduct the survey flawlessly. USA Ltd is one of them, having 25 years of experience in this field. From piloting the pollution survey to manning the mainline survey, it specialises in the pipe and drains inspection, repair and renovation like none. Equipped with GPR tools and technique, the experts can simplify your job and help you achieve your targets.

Postscript:

Ground inspection techniques have indeed improved over the years. GPR is just an exemplary case underpinning the fact. Agree?

How Top Hat Sewer Lateral Repair Works

Image
  When it comes to drainage systems and water main maintenance, this is the moment of “top hat” technologies. Today, the top hat techniques and technologies apply for a broad range of jobs including sewer upgrading, replacement, and cleaning. This is not only on-trend but crucial for improved efficiency and needs of the hour. The same goes for sewer lateral connection repairs. If you are at the far end of appointing a drainage services provider in Ireland, here’s an overview of the working process. What Is Top Hat Sewer Lateral Repair   In order to seal the connection between the pipe and the sewer or lateral drain and make it leak-proof, a liner is used. The Top Hat liner looks exactly like a top hat, which is made of resin-impregnated, fiberglass laminate, and the shape makes it perfect to wrap the pipeline and   fit within the lateral service connection. For lateral drain repairing projects, Top Hat lining is often combined with CIPP Lining, but it can be used a...

Understanding Underground Pollution Survey - Procedures, Parameters And Trends

Image
  From Industrial Units to Residential pipelines, all these structures are prone to get cross-connected to surface water drainage systems, resulting in the confluence of foul water and wastewater with that of outfall streams that may be natural water bodies or river and ultimately the oceans. With an end-to-end Pollution Survey, it is probable to inspect the contamination level and possible to take valid steps for Waste Water Treatment Compliance. Here is an overview of how pollution surveys work for Wastewater Treatment purposes, what are the parameters and current trends. Common Parameters For Underground Pollution Survey     So What Really Is Considered As Underground Pollution? It is denoted by the wide range of harmful substances including chemicals, household and untreated wastes, agricultural wastewater etc that travel through underground pipelines and enter the Groundwater. In Ireland, at least 20% of the drinking water supply is sourced from Groundwater....

Underground Surveying & Manhole Benching – The Key To Drain Blocking

Image
Did you know that drainage inspections are an essential part of maintaining sewer systems? Well, the ideal way to maintain a healthy drainage system is through prevention. And, undertaking a professional drain survey can help prevent sewer problems from worsening. Using specialist underground surveying is, therefore, important to examine and inspect your drains. Manholes are an indispensable part of drains, giving clear access points to the underground pipes and allowing surveys to be carried out above the ground to inspect the condition of pipes. Sewer surveys are used for assessing the situation of a drainage system through the utilisation of a closed-circuit television camera. Once they gain access to your drains, the engineer will insert a CCTV camera inside to capture real-time drain inspection footage. After assessing the footage, they can produce a drain camera survey report with recommendations. Here’s an insight into all you need to know about manhole bench and drain surveys....
