An Overview Of Ground Penetrating Radar

Initially developed to help map geological features, today ground penetrating radar (GPR) is useful for a range of different civil engineering survey applications. Other common terms for GPR include ground radar, sub-surface radar, surface-penetrating radar, ground-probing radar, or impulse radar. A GPR survey is a uniquely non-invasive, non-destructive tool for exploring subsurface features. Civil engineers prize ground penetrating radar as a highly flexible NDT survey technique.

Ground penetrating radar is suitable for use on many kinds of surface and subsurface materials, including soil, masonry, concrete, and asphalt.

Applications For Ground Penetrating Radar

Companies offers a range of different ground penetrating survey services. The ones listed here are particularly common in the construction industry:

* Construction Detail Survey: GPR can make general construction arrangements clear, showing the thickness of layers, changes in materials, and the location of structural steel.

* Concrete Mapping Survey: Ground penetrating radar can be used on almost any sort of concrete construction: floors, decks, slabs, walls, tunnels, balconies, and more. GPR offers greater depth and more accuracy than most other survey methods, easily locating and mapping rebar, conduits, and tendons.

* Floor Slab Survey: This rapid survey delivers actionable details of slab construction, such as overall thickness and reinforcement distribution. GPR is also capable of detecting and mapping under-slab voids. This can be vitally useful in identifying trouble spots in heavily-trafficked slabs (e.g. warehouse floors) before they fail.

* Chimney Flue Location Survey: GPR is a non-intrusive tool for mapping out chimney flues in existing construction. Results can be delivered as CAD drawings, marked up on-site, or both.

* Embedded Steel Location: A radar survey can find embedded steel within masonry construction. The non-intrusive nature of a radar survey makes this particularly well-suited to investigating historical and listed buildings.

* Road/Runway/Pavement Survey: GPR is easily capable of identifying the thickness of various paving layers, detecting sub-pavement voids, and spotting points where layers are beginning to de-bond.

* Utility Survey: Ground penetrating radar is the only tool that can reliably and non-intrusively identify both metallic and non-metallic utilities under the surface. GPR works to identify water, gas, sewer, electric, telephone, and fiberoptic utilities.

* Buried Object Location: GPR surveys are useful in searching for buried objects of all sorts. They can help locate underground storage tanks (UST), contribute to forensic investigations, and find gravesites.

* Hazardous Waste: Once buried storage tanks, pipes, or drums have been located, ground radar can in some cases be used to detect leakage or contamination.

* Foundation Investigation Survey: Ground penetrating radar provides comprehensive data on footings and foundations. It can be used to locate, map, and investigate the condition of all such subsurface work.
