It is used to investigate building foundation piles and, with the use of “cross-hole” ultrasonic pulses, allows for precise, high-resolution testing.

An ultrasonic wave is sent from a transmitter to a receiver and automatically transmitted by the device along the entire length of the pile inside the embedded tubes during curing. The speed and energy of the sonic wave are greatly influenced by the quality of the concrete. Therefore, it is possible to analyze the characteristics and obtain a 2D and 3D tomographic representation called a logging survey.

The test can be performed on any type of foundation or concrete structure with two or more boreholes capable of holding water. It can also be applied to piles or submerged structures that, lacking internal access pipes, have been fitted with external ones. Tomographic tests are carried out when the detected defects are critical and require in-depth analysis.

The Crosshole system consists of:
-Portable computer unit
-High-speed data acquisition card
-Crosshole software for data acquisition and analysis
-Descent and ascent tripod with depth measurement
-2 interchangeable probes, one transmitter and one receiver
-Ultrasonic pulse generator to excite the transmitter
-Amplification and cabling systems
-Two 80m cable reels

All these components are connected to each other by cables to form a complete system.
