Structural Elements

The modern footbridge is synonymous with sustainability in urban planning. Around the world, from London to Seoul, ambitious footbridge designs showcase the best of sustainable architecture. For those who prize creativity in their projects, Ductal® is an ideal tool: lightweight and slender for elegant designs, yet sustainable and durable so as not to compromise on practicality for beauty.

 

Footbridges

A footbridge’s simple function gets you from A to B, but there are many ways of doing so. If you are looking to design a footbridge that can mark a city, Ductal® offers the ability to create fine, intricate shapes, with all the ease of working with precast concrete. Our range of colors and finishes will ensure you get the look you desire.

The very high compressive strength of our UHPC combined with prestressed solutions allows longer spans without supports. From design to construction and beyond, the benefits are many: we can promise you a technologically advanced solution and the relative ease in design and construction that comes from working with pre-cast concrete forms. The proof? Our world-leading span over height ratio for concrete bridges achieved with the MuCEM footbridge in Marseille, France.

Architectonic structures

Ductal®’s strength and durability, combined with the controlled manufacturing environment of a precast plant, bring the sculpturesque forms of innovator's dreams to life with unique architectonic structural elements. If you are looking to bring something different to your project, and you value aesthetic ingenuity, Ductal® is just the right material.

The principle reason Ductal® is so durable against adverse conditions and aggressive chemical agents is that it has a remarkable impervious pore structure. Its cementitious matrix has this impermeable quality due to the denseness of its particle packing and the fact that what nanometer-sized pores do exist are unconnected. As a result, from columns and beams to roofs and canopies, there is no end to the possible structural applications of Ductal®.
