Cross Hole Sonic Logging (CSL) pipes na special tubes dem put inside deep foundation element dem—mainly bored piles, diaphragm walls, and secant piles—to carry out non-destructive integrity testing for structural concrete. Dem fabricate dese tubes from high-strength plastic or steel, and dem use am for acoustic pathway for sonic probes to transmit and receive ultrasonic wave dem through di full depth of di foundation. Dis way engineers fit detect problem dem like concrete segregation, void dem, crack dem, necking, and contamination wey fit compromise bearing capacity or load transfer ability. Normally dese pipes get 50–60 mm outer diameter with wall thickness of 3–5 mm—size sotey dem stay rigid when concrete pour but small sotey dem no cause stress concentration inside di pile structure.
