Injection Start - Checking the reaction time of KÖSTER Injection Gel G4
Injection and checking the pump settings
Visible signs of material distribution were observed on cracks over 15 m away from the injection points
The low viscosity of the material allowed a thorough distribution of the material in the joint and the horizontal cracks in the slab
Overview of injection site
With a second KÖSTER Acrylic Gel Pump, the injection rate was increased and the outflows were closed faster
Overview of injection site using two pumps
Removed packers and sealed drill holes
Joint injection finished and set up for new drill holes
To address the damaged area on the side of the slab, additional drill holes (46 mm) had to be made for further injection
The injection through the newly placed packers was essential for reaching the damaged area
After approx. 50 min injection time, the acrylic gel KÖSTER Injection Gel G4, had already sealed parts of the cracks
Shortly after, the complete section was successfully sealed
