Can Ground Penetrating Radar See Through Concrete

Ground penetrating radar is a geophysical method that uses radar pulses to image the subsurface.

Can ground penetrating radar see through concrete.

Also concrete is conductive when it is fresh but becomes non conductive as it cures. For a general question like how deep can you see with ground penetrating radar gpr the answer is usually a range such as 2 to 10 feet or up to 18 inches. During our concrete imaging and scanning surveys we harness the same ground penetrating radar gpr technology used to conduct our utility locating surveys the only difference being that we replace the mid frequency 400 mhz antenna and large survey cart with a higher frequency antenna and small handcart. Although radar can easily see conductive materials such as metal and salt water it cannot see through them.

It is a non intrusive method of surveying the sub surface to investigate underground utilities such as concrete asphalt metals pipes cables or masonry. This means there is an inherent risk of striking rebar electrical and communications conduits and post tension cables during the cutting coring or drilling process. Gpr can have applications in a variety of media including rock soil ice fresh. Concrete scanning with ground penetrating radar technology with new build construction and renovation projects the likelihood of needing to cut or core a concrete slab is high.

Canwest will be on your site within hours of your call to quickly scan large sections of concrete. However for a clients specific survey area and survey goals these kinds of answers are often not satisfying and can be misleading. Ground penetrating radar gpr uses a high frequency radio signal that is transmitted into the ground and reflected signals are returned to the receiver and stored on digital media. The computer measures the time taken for a pulse to travel to and from the target which indicates its depth and location.

Radar is the only remote sensing technology that can detect both conductive and non conductive materials. There is inherent risk of striking rebar electrical and communications conduits and post tension cables during cutting coring or drilling process. It is less effective on some very electrically conductive media such as saltwater and most clays. Concrete scanning with ground penetrating radar with new build construction and renovation projects the likelihood of needing to cut or core a concrete slab is high.

It can even detect the rebar in the concrete for engineering purposes. Is ground penetrating radar portable. Gpr can detect through concrete even if it is reinforced. Ground penetrating radar can be used on rock soil ice fresh water pavements and structures concrete or otherwise.

Gpr is very portable and is easily moved over each site with just one operator.
