T&A Survey’s TISA 2D Borehole Radar is a simple, safe and clear way to acquire data of the subsurface. The TISA 2D tool can be used in various shallow and deep underground applications where traditional surface ground penetrating radar (GPR) cannot penetrate and is beyond its range. Dense urban environments, for example, present different challenges than open unobstructed areas where GPR is most often used. What if the buried object is under a concrete slab or under a building?
Only one borehole
What makes TISA 2D unique is its reflection mode, where both antennas are located in a single tool inside the same borehole. The transmitted pulses are reflected by a nearby object and detected by the receiver antenna. The depth of the antenna system and the measured pulse two-way travel time defines the 2D position of the detected object. The TISAMap software allows for an efficient and state of the art processing, interpretation and display of all your recorded borehole data.
Projects
The TISA 2D tool has been successfully used in a wide range of projects from sinkhole detection, locating concrete walls to the detection of unexploded ordnance (UXO). TISA 2D is most often used in Europe in identifying and aiding in the recovery of WWII aerial bombs. UXO detection might be limited in your country, but it does demonstrate the tool’s ability to find metal objects like underground storage tanks (UST) or buried steel drums.
