HEMCO Crosshole Sonic Logging (CSL) tubes provide an accurate, cost effective and non-destructive means of investigating the integrity of concrete in drilled cast-in-situ piles. Specially designed rubber gasket at the joint ensures proper sealing and quick installation.

Salient Features

1) No welding required at jobsites
2) Quick installation within rebar cage
3) Each tube is pressure tested in factory against leakage

Main Objectives of CSL Testing

CSL testing can provide valuable feedback regarding following possible defects in cast-in-situ piles:

• Honeycombing during the concreting operation
• Washout of cement due to groundwater flow
• Cracks in pile shaft due to shrinkage, thermal stresses or defects in concrete
• Inclusion of foreign material (e.g. soil) during the concreting operation
• Necking of the pile due to collapse of sidewall during withdrawal of the temporary casing

The CSL tubes are installed within the steel cage at the time of fabrication of the cage. At the time of lapping of steel cages, the lightweight CSL tubes can easily be press-fitted together thanks to the specially designed joint as shown in the adjacent sketch.
