Concrete Repair at Beams and Slabs at Container Terminals

Our company was appointed by the terminal operator as a term contractor to carry out routine maintenance works including concrete repair works for defective slabs and beams.

The concrete repair works in this project included erection of temporary working platform under the quay structure, breaking out of defective/spalling concrete, cleaning of corroded rebars, augmenting rebars and spraying of repair mortar.

In this project, spraying of repair mortar was selected as the method of concrete reinstatement as spraying repair mortar at large areas of repair could offer rapid progress and lower cost.

After completing the concrete repair works, a series of tests, including pull off test to check the bond strength between the repair mortar and the substrate, would be conducted to ensure the works complied with the requirements specified in the specification.
