TDR does not work in highly granular materials and a gypsum block is only
appropriate if there is a high clay content or the materials are expected to
get very dry (>100kPa)

It sounds like you have a quarry rubble - if this is so then  most useful
device would be a granular matrix sensor such as the 'Watermark'.

Sorry, I don't know a UK supplier.
