Application

Description

The repair/strengthening or regeneration/reinforcement solution consists of creating/casting, from the inside and in contact with the existing metal culvert, a resistant structure capable of carrying/supporting on its own the permanent loads (weight of the backfill) as well as the traffic overloads applied on the culvert.

Using the innovative process developed by the Ductal® and Freyssinet teams, a thin layer of Ductal® Shotcrete ( 7.5cm in average thickness) was applied/sprayed enough to strengthen the existing structure without requiring extensive preparatory works.

Challenge

Description

Reinforcement has been put in place over the entire culvert in order to be able to stop the concrete application quickly depending on the production of the day, but also to offer more visual cues to workers and thus avoid excess thickness/rebound.
