Rue 38 got all dressed up to the 9’s with the setup of the first liners.

In our first episode, both the preparatory work and the routing of the liners were ongoing.

In-field training, still provided by Cyrille MAUFAY, continued in December with the laying of the first stretches of close-fit lining.

Rue 38 (a top priority in the programme prepared by Redal) was therefore transformed for a few days into a trenchless works demonstration area.

The aim of the first drive was to rehabilitate a 30m, 300-diameter stretch between too shallow manholes. Every stage of the protocol was followed:

• cleaning of the stretch,
• checking of its condition via video inspection,
• insertion of the liner,
• UV polymerisation,
• waterproofness test.

The aim was also to limit disruption to locals at all times.

To date and in this very specific context (narrow street, complex routing of equipment, pandemic, etc.), the team 100%-autonomously carried out 30+ drives covering a total distance of approx. 780m!

N.B. This close-fit lining worksite, which fully fits in to the International Department’s Growth & Diversification Plan, is practically a first in the country…

After the next episode, called “SADE in Stark Trek mode”, you’ll understand why…

Congratulations to the teams!
