Sprayable membrane for water incomes treatment

publié le 3 novembre 2010

Water incomes of a twenty meters long section in the Col de Rousset tunnel have been treated by sprayed membrane Masterseal ® 345. The testing program was organized by the CETU in collaboration with the District Assembly of the Drôme (Conseil Général 26), the sprayed membrane supplier, BASF Construction Chemicals and the company Colas Rails, specialized in tunnel repairs. A video describes the steps of this repair technique and retraces the main lessons drawn from this experiment.
