In November 2009, CF + rehabilitated a 1500mm diameter prestressed concrete pipe on de la Cathedral Street over a length of approximately 60 meters.
This master watermain had weaknesses that needed to be corrected earlier than later.
The location of the pipe did not allow for trench replacement due to the presence of many public utilities.
By installing a CFRP (Carbon Fiber Reinforced Polymer) reinforcement, it has been possible to put back this watermain into service in record time. It took a little less than 15 days to complete this work.
