Ductal® UHPC Shotcrete: the global response to your specific issues
The result of research by LafargeHocim R&D teams and Freyssinet, this new Ductal® Shotcrete solution represents a technological break in the field of UHPCs. It is the only one on the market that can be applied directly to vertical walls or vaults by spraying.
An application facilitated for exceptional durability
In the reinforcement of metal culvert, the application of Ductal® shotcrete does not require any extensive preparatory work besides a quick cleaning of the works by simple sandblasting. The time periods of your work sites are drastically reduced, which allows you to limit the time when works are closed.
Applied by spraying directly onto metal walls, thin layers of Ductal® Shotcrete (less than 6 centimeters), provide a rapid and durable regeneration and reinforcement of the infrastructure. This solution has the advantage of not altering the characteristics of works while ensuring that they are returned to new, almost identical, condition.
Due to its qualities of durability, its resistance to damage from chemicals and weather and from collisions and abrasion, it guarantees effective and long-lasting renovations.
Finally, renovation with Ductal® Shotcrete prevents waste. On a duct with a diameter of 2.5 meters, a 60 mm layer is sufficient (versus 15 to 30 cm for sprayed or poured concrete). Therefore, the geometry of the culvert is completely protected and the reduction of their diameter is extremely low, less than 2% for a nozzle with a 2.5 m diameter.
