Dear Mark, I have quite a lot of information if you could you be a little more specific. Is it into rock or soil? What type of grout are you using? At what depth are you grouting? What method are you using, simple packer, TAM, jet grouting On the lab scale, some pretty good experiments were undertaken by the US Corps of Engineers on artificially induced cracks. These are referred to in Houlsby, A. C. Construction and design of cement grouting : a guide to grouting in rock foundations For field measurements of general fluid movement see tracer work by Shapiro AM and Hsieh PA http://wwwrvares.er.usgs.gov/nrp/proj.bib/hsieh.html This can be used to predict grout flow. I am not aware of any field monitored grout tests showing grout flow.
