What is a cross hole sonic logging test?

Cross Hole Sonic Logging (CSL) is a non-destructive testing method used to assess the homogeneity of concrete in large diameter piles and diaphragm walls. It helps detect potential anomalies such as voids or inclusions that could compromise the structural integrity. This testing is crucial for ensuring the safety and longevity of foundational elements in construction projects.

How does Cross Hole Sonic Logging testing work?

CSL testing involves placing a pair of transceivers in water-filled access tubes installed within the concrete structure. One probe transmits a high-frequency signal that passes through the concrete and is received by the other probe. This process is repeated across different tubes to capture comprehensive scans of the structure. The collected data, including signal strength and travel time, is analysed to identify any anomalies in the concrete.

What are the key benefits of using Cross Hole Sonic Logging testing?

CSL testing offers several benefits, including enhanced safety by identifying potential structural issues early, improved quality assurance by verifying the consistency of concrete, and cost savings through early detection of defects. It also supports sustainability by reducing the need for extensive repairs and material wastage.

How does SOCOTEC ensure the reliability of Cross Hole Sonic Logging testing?

SOCOTEC uses equipment conforming to ASTM D6760 standards and is UKAS accredited (Cert.Nr. 0001), ensuring high accuracy and reliability in testing. Our team of experts, strategically located across the UK, provides swift and efficient service, delivering comprehensive reports that help clients make informed decisions.

Can Cross Hole Sonic Logging testing be performed on all types of concrete structures?

CSL testing is particularly effective for cast-in-place structures where steel reservation tubes have been installed within the reinforcement cage before the concrete pour. It is commonly used for large diameter piles and diaphragm walls, providing a detailed assessment of concrete quality throughout the structure.

What is the significance of the data obtained from Cross Hole Sonic Logging testing?

The data obtained from CSL testing includes signal strength and travel time, which helps determine the concrete's homogeneity and detect any defects. This information is crucial for assessing the structural integrity and safety of the foundation, allowing for timely interventions if necessary.
