Hydro Demolition of 3 Large Concrete Columns in Singapore

When the Main Contractor had Grade 85 concrete not meet the specification, it was essential to remove the material without damaging the re-bar. GOS solution was to mobilize two machines capable of 30,000 psi with high Volume output to remove or demolish the very hard concrete so that the columns could be re-cast with the Correct Grade. The Main Contractor was able to progress with the Project without undue loss of time.
