3 Key Advantages Of Using Ground Penetrating Radar For Construction Surveys

Ground penetrating radar (GPR) is a type of geophysical technique that uses electromagnetic radiation to image the subsurface. It has many applications in construction surveys, including locating buried pipes and utilities, mapping foundations and floors, determining groundwater depth and investigating construction defects.

GPR is often used as an alternative to traditional methods like digging trenches and boreholes or using expensive equipment such as ground-penetrating tomography. GPR can be used in urban areas where digging or boring is not possible because of cost or environmental concerns. It can also detect objects that are buried under concrete slabs or asphalt roads.

Here are three key advantages of using GPR for construction surveys:

1) It Provides Three-Dimensional Images Of The Subsurface Without Requiring Digging Or Boring

Ground penetrating radar is a non-destructive testing method that provides real-time data without harming the surrounding environment or property. Unlike other methods such as drilling or coring which require digging holes in the ground and boring into the earth, GPR does not require any digging or boring to collect data about underground structures or utilities. 

The combination of the powerful transmitter and receiver allows you to obtain accurate information about the material under the surface of the earth. This includes features such as soil type, rock type, voids (i.e., empty spaces), moisture content and many more features that are important for construction surveying.

2) It Does Not Require Heavy Machinery Like Excavators, Bulldozers And Backhoes

Excavators, bulldozers and backhoes are powerful machines that can dig up large sections of land with ease. However, these machines require a lot of maintenance and fuel, which can make them expensive to use.

Ground penetrating radar does not require any heavy machinery during the process. Instead of using excavators or backhoes to clear the ground for surveying purposes, ground penetrating radar uses radio waves to scan the surface for buried objects. The device sends out radio waves that bounce off buried objects and return to the device as an image on a screen. The operator then uses this image to identify any buried objects within the area being surveyed.

3) Ground Penetrating Radar Allows You To Investigate Even Difficult-to-Access Areas

GPR can penetrate through layers of concrete, asphalt and other materials that would otherwise obstruct traditional methods of investigation. This means that it can be used to investigate difficult-to-access areas such as pipes, tunnels and basements without causing damage to them or slowing down progress on-site. It can also detect cracks, voids and other defects in structures that are difficult to see with the naked eye. This makes it ideal for surveying the integrity of buildings and infrastructure before work commences on them.
