When grouting in karst terrain (relatively deep depth to bedrock, say 50-ft plus) for the purposes of mititgation
of sinkhole development, what is the most rational methodology for determining maximum grouting pressures and
preventing hydrofracture in clayey soils....assuming no groundwater?
Also, is cap grouting at the bedrock interface the best approach, or should pressure grouting start at rock
and continue to near surface.
