Concrete Repair Works of Spalling/ Defective Concrete at Beams and Slabs at Building

Our company also carries out routine maintenance works including concrete repair works for defective walls, slabs and beams at different kind of building.

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.
