Can Ground Penetrating Radar See Through Concrete

Gpr can have applications in a variety of media including rock soil ice fresh.

Can ground penetrating radar see through concrete.

There is inherent risk of striking rebar electrical and communications conduits and post tension cables during cutting coring or drilling process. Canwest will be on your site within hours of your call to quickly scan large sections of concrete. It is less effective on some very electrically conductive media such as saltwater and most clays. Our ground radar technology creates a detailed three dimensional image that makes job planning a snap.

Ground penetrating radar is a geophysical method that uses radar pulses to image the subsurface. 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. 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 is very portable and is easily moved over each site with just one operator.

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. Gpr scanning technology is faster and safer than radiography x rays which uses radiation for concrete scanning. However for a clients specific survey area and survey goals these kinds of answers are often not satisfying and can be misleading. It is a non intrusive method of surveying the sub surface to investigate underground utilities such as concrete asphalt metals pipes cables or masonry.

Ground penetrating radar can be used on rock soil ice fresh water pavements and structures concrete or otherwise. This nondestructive method uses electromagnetic radiation in the microwave band of the radio spectrum and detects the reflected signals from subsurface structures. Also concrete is conductive when it is fresh but becomes non conductive as it cures. It can even detect the rebar in the concrete for engineering purposes.

Gpr can detect through concrete even if it is reinforced. Although radar can easily see conductive materials such as metal and salt water it cannot see through them. Radar is the only remote sensing technology that can detect both conductive and non conductive materials. 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.
