Address the most challenging structural and durability challenges with high-strength, ductile and self-compacting solutions. Whether precast or poured in-situ, these can meet the most demanding requirements – regardless of complexity.

 

Our Ductal® Infrastructure solution is specifically engineered to fundamentally enhance the performance of new and existing structures.

Superior performances in compressive, tensile and flexural strengths, combined with high abrasion resistance, crack control, and high impermeability makes it perfect for strengthening, waterproofing and protecting structures, extending their service life while reducing maintenance costs.

01. What it is

 

The material’s high mechanical properties combined with exceptional ductility allows for the construction of lightweight yet enduring prefabricated bridges, strengthening bridge decks and repairing vertical structures that display the best in innovative techniques and durability requirements – along with endless possibilities for improved aesthetics.

The high prefabrication potential of Ductal® accommodates projects at different scales, reducing the size and complexity of structural connections and rebar detailing. This allows for a better exploitation of mechanical resistances, even in the context of existing traditional concrete construction.

02. Optimization

 

Whether cast in place or precast, Ductal®’s flexural and durability advantages offer a great potential to explore for rehabilitation projects, and provide a reliable, durable solution to extend the lifespan of structures such as bridges, piers, girders, and joints.

Its fluid, self-consolidating consistency makes it ideal for casting in congested areas, without the need for vibration. Typical design strength can be reached in a short amount of time.

Its innate strength allows for the creation of thinner structural elements, and just about any new shape or geometry imaginable can be brought to life.

03. Implementation

 

Thanks to this combination of form and function, Ductal® infrastructure satisfies necessary requirements of the technical specifications while providing a cost-efficient solution for projects.

Ductal® ultra-high performance concrete marks a clear departure from conventional and high- strength concretes both in terms of its mechanical properties and behaviour, providing long-term durability and protection even in the most aggressive of environments.

04. Benefits

 
  • Closure Pour Connections (i.e. Joint fill)
  • Link slabs and expansion joint headers
  • Beam end and bearing encasements
  • Column and pile jacketing
  • Protection of hydraulic and marine structures
  • Slender precast elements

05. Applications

Discover our projects

 

Pulaski Skyway

A structure that symbolizes US bridge engineering of the 1930s, the Pulaski Skyway, which links Newark to Jersey City has been partially closed as it undergoes a considerable rehabilitation - the largest in its history. The project was a perfect opportunity for the Federal Highway Administration (FHWA) and the New Jersey Department of Transportation (NJDOT) to take full advantage of the technical benefits offered by Ductal® Infrastructure joint fill over the 5.5km long bridge from Newark Airport to the Holland Tunnel.

 

Mauves sur Loire bridge

The rehabilitation of Mauves-sur-Loire bridge consists in substituting the existing deck (3,500 m²) made of brick vaults with a thin deck made of thin precast UHPFRC slabs. The main objective of the project is to upgrade this historic landmark by increasing its bearing capacity and allowing the addition of cantilevered footbridges.

 

Dominie Creek

Dominie Creek bridge lies on ancestral territory where Caltrans and Tolowa Dee-ni’ Nation worked together to replace the old dilapidated box culvert structure. The finished bridge has an emblem of spawning salmon at each abutment barrier wall which was inspired by the locations salmon and trout spawning.

 

Grafstal road bridge

The concrete of the abutments and central pillars of the Grafstal road bridge (municipality of Lindau) above the A1 motorway showed damage due to chloride infiltration.
