The tunnel construction will ensure adequate treatment of wastewater from the urban centres of Soria and Los Rábanos, thus avoiding environmental damage to the receiving environment.
The HK tunnel boring machine drilled the 5-kilometre-long emissary tunnel with very different types of soil, from sand with a lot of water to clay, passing through different areas of very difficult faults and which needed very special treatment to be able to advance properly.
The technical service and assistance of TNL18 has been essential for the correct progress of the TBM.
For soil treatment, using the foaming agents ACTISOYL 100, ACTISOYL CC and the polymers ACTI+ WW and ACTI+ ABS.
For tail sealing, ACTISEAL PS1, ACTISEAL FF and ACTISEAL 18 mastics were used.
For main bearing protection, ACTISEAL MB mastic and GR4520 Ep2 grease were used.
