There are several myths surrounding the use of GPR devices for various purposes. Such myths can hamper proper use of GPR equipment during critical investigations such as locating underground conduits or concrete slab rebar. As such, we will be looking at few of these myths and try to debunk them.
Up to what depth can a GPR system detect underground utilities? This is a question that many people have when locating underground conduits when concrete reinforcement is the aim they want to accomplish.
But this question does not have a simple and straight answer. The scan’s scanning depth quality depends on several factors, which we will be exploring in the following sections. Let us delve into the details.

During construction it oftentimes necessary to do work on pre-existing concrete. Cutting, drilling, and coring are some procedures done to concrete walls and slabs. The concrete may contain post-tension cables, conduits, rebar, among other things. If these are hit during cutting, drilling, or coring it can result in significant damage. So, in the following sections we will look at:
- How to Reduce or Eliminate Risks while Invasive Work is Being Done
- Why Skipping Concrete scanning is the Wrong Thing to Do
How to Reduce or Eliminate Risks while Invasive Work Being Done
Concrete scanning is the right way of eliminating or reducing risks that exist when any type of invasive work is done on existing concrete reinforcement. Scanning helps to trace elements that are hidden under the surface and prevents technicians from hitting them.

It is a fact that if something gets overheated the chances of it breaking down or malfunctioning increases dramatically. For this reason, using thermography is quickly becoming a necessity for ensuring appliances and other equipment perform as expected without unnecessary breakdowns. It is worth mentioning here that all the objects with a temperature higher than -273OC tend to emit infrared radiation.
The purpose of thermal imaging equipment is to capture this infrared radiation and turn into an image that is clearly visible. In addition to this, thermal imaging cameras instantly measure temperatures and convert available images into an understandable electronic format so that the available data can be further processed.

GPR is very well known for its conduit detection effectiveness and for its utility in concrete scanning in Montreal and Ottawa. Here are the answers to frequently searched for questions about Ground Penetrating Radar (GPR):
How far can GPR go into the ground?
Well, it all depends on the kind of application you want to do with it. If you want to use it for concrete scanning, it is about 10 feet into the ground. For areas with clay and grass, it is only a few feet. Finally, for sandy soils, the GPR can go down to 30 feet underground. Of course, it all depends on the site conditions and if need be a larger antenna is used to allow better penetration.

Ground Penetrating Radar is a technique used for locating or confirming the presence of utilities buried underground. Some of the utilities detected by this technique include underground water and sewer pipes, optical and electrical cables, shallow unexploded ordnance, and wood among others. As a technology, GPR has helped immensely to save underground utilities that could have been damaged during construction projects. This has led to faster completion of projects, minimal public disruption due to damaged utilities, and proper planning and execution of projects.
It is a relatively new technology, and as such, its adoption is still slow outside civil engineering applications. However, the future is very bright for the technology as awareness about its importance increases, and more and more industries and government departments are adopting it as a tool to aid in their planning. Read below for an overview of what we can expect about GPR in the coming years.

Concrete scanning with GPR has been used for a very long time now, longer than we think. Nowadays, it has become an indispensable tool for workers in construction as it is capable of conduct detection, making it safer by avoiding pipes or other important components in the ground.
It has been noticed that more and more companies specialize in concrete scanning in Montreal as they see it as the future of underground scanning. In time it will improve and become revolutionary, more than it already has. However some important questions to be asked include how this technology came to be? And what can you really do with a GPR?

The global pandemic has had a real negative effect on the construction sector in the world. Some companies have stopped construction and others are now doing little work. Until the situation changes, it will remain that way. For the companies that are still working a lot of problems are looming. Among them are the safety and health of their workers. But other things have to be considered. How does this virus impact construction right now?

If there is a need to cut into concrete then it is necessary to identify electrical lines and metal targets before it is carried out. If the location for cables, rebars, and conduits are not marked before cutting, and digging, drilling, trenching, or coring is carried out then it can easily result in mishaps and cost overruns. In the following sections let us look at how GPR used for concrete scanning in Montreal can help you save on cost.
How can GPR help avoid mishaps and save on cost?
At the time of concrete drilling or cutting if buried or embedded obstructions get hit then it can have disastrous results. It can cause project delays, increase expenditure, and result in worker hazards. In addition, if a rebar that is helping to strengthen the beam structure is cut, this may result in damage and failure of the structure. Moreover, if electrical conduits are cut then it can cause serious injuries as well as result in the shut down at job sites.

There are different types of instruments which are used for concrete scanning with their respective features and benefits. Our aim here is to look into different instruments that are used for this purpose.
Instruments Used for Concrete Scanning
Ground Penetrating Radar
If concrete scanning is the goal then concrete scanning with ground penetrating radar (GPR) in Quebec provides the best result. GPR is commonly used before tasks such as cutting or drilling, scanning of concrete structures for spacing and cover, as well as diameter estimation. GPR can also be utilized to locate buried tanks, metal as well as non-metal underground utilities, and other types of buried objects (metal and non-metal).
