A66 Salzbachtal Bridge, Germany
The A66 Salzbachtal Bridge, located in Wiesbaden, Hesse, is a 304-meter-long, four-lane motorway bridge on the A66. Originally constructed in the mid-20th century, the bridge has been subject to wear and tear due to increasing traffic loads and aging infrastructure.
Foundation piles are fundamental to the stability and longevity of bridge structures. Ensuring their integrity is crucial to preventing potential structural failures. dextra played a pivotal role by supplying approximately 10,000 linear meters of Sonitec CSL (Cross Sonic Logging) tubes.
Sonic tubes are essential components in the CSL testing method, which is widely regarded as one of the most reliable techniques for assessing deep foundation integrity. Sonitec, designed for easy installation within the reinforcement cage, facilitates accurate cross-hole sonic logging, allowing engineers to precisely detect and locate defects within the piles.
