The Damages (10 April 2015)
Removing of Loose concrete and installation of chipping aggregates for Grouting. Chipping Concrete will help to reduce the heat pressure of the grout during the grouting period. 10-15 MPa pressure will be used to grout the defected area (14 April 2015)
It was found out that the degree of damages was extended not visible to the eyes due to small opening. It was decided to hack the area again about 200-300mm and 250mm deep
The extent of the damages was determined and installation of appropriate amount of chipping aggregate or granite aggregate was installed. 1 inlet and two outlet of the pressure grout will be installed in the formworks to ensure the grout will travel all the void spaces and leave no air bubbles to ensure all grouting will be completed (17 April 2015)
My next post will be the grouting itself. on 21 April 2015
