Near Field Processes (NF-PRO) - Experimental Setup

The laboratory programme consists of long-term, controlled saturation/desaturation experiments with the two granite cores. The experimental setup allows continuous recording of the TDR reflectograms and changes in the weight of the granite cores.

The experiments will be carried out under controlled temperature and relative humidity conditions of the air around the cores. Two experiments run in parallel:

  1. long-term controlled saturation and desaturation test on the matrix core, and

  2. controlled saturation and desaturation test followed by a tracer test on the shear zone core.

The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
