We are pleased to announce that we now provide GPR services to our clients.
GPR (Ground Penetrating Radar) is the general term applied to techniques which employ radio waves, typically in the 1 to 1000 MHz frequency range, to map structures and features buried in the ground (or in man-made structures). Ground Penetrating Radar works by emitting a pulse into the ground and recording the echoes that result from subsurface objects. Essentially, with our Noggin unit, we'll be able to interpret the data to identify underground pipes, cables, voids, geo-physical issues in the sub-surface, frankly we could possibly interpret forensic investigations.
We have two units, Noggin for large outdoor surveys for sub-surface work & Conquest for concrete assessment,
Noggin, has various uses for sub-surface detection, some of these areas that we can use the Noggin are, Sub-surface Engineering, Concrete & Pavement, Geo-technical Environment, Archaeology & Cemeteries, Forensics & Military, Mining & quarrying as well as Agriculture & Forestry. At, HTG we mostly will be using the unit for Sub-Surface Engineering along with concrete & pavement however the wide usage of this system can allow for greater applications.
With the Conquest we can easily identify rebars, pipes, and conduits within concrete up to 24" thick (concrete build up will ultimately determine depth of penetration) This system can be used to identify where not to drill or dig within concrete, it has many other uses. When cutting and coring for renovation and repair, avoiding reinforcing bars, post-tension cables and embedded conduits is a priority. GPR can sense both metallic and non-metallic features making it a versatile imaging tool. Construction records for many buildings are not readily available and construction often differs from design resulting in GPR being the only way to confirm what is there.

Thanks for helping me understand that the pulse emitted by the GPR would be recording echoes which would mean that there are subsurface objects. I can imagine how helpful concrete scanning would be essential before anyone starts cutting the material and getting a construction project started. It will be for everyone's safety and convenience, especially when they have to avoid areas where there are utility lines under.
