An Ultra-High Performance Material

Architecture Presentation

Building better cities

Defining UHPC“Materials with a cement matrix & characteristic compressive strength in excess of 20,000 psi, possibly attaining

36,000 psi -- containing fibers in order to achieve ductile behavior under tension.”

- SETRA (French Society of civil Engineers)

The Living Wall

Ductal® is a revolutionary, ultra

high performance composite

material that provides strength,

ductility, durability and aesthetics.

This unique combination of superior

properties facilitates the ability to

create innovative designs with new

shapes that are thinner, lighter and

more graceful.
