Assume that the hole takes 14.25 cu ft of grout [ 405 litres] in this period.
The rate of take continues to decrease, but even so, is still a large quantity of cement.
SUMMARY OF APPLICATION SO FAR - at 1 hour, 15 minutes:
Permeability before grouting is more than 100 lugeons (high)
Water:cement ratio = 0.5:1. Pressure builds up to 10 psi [0.7 bars]
Total cement injected so far
You do not need to decide what to do next because the grout is now as thick as it can be. There are no alternatives to just letting the simulation run on to the end of the grouting.
