Sideau by Agra-Wool International

Whether it’s a wedding background, an immersive event installation, or a striking hotel display, large-scale floral designs demand more than creativity alone. They require a reliable foundation - one that supports every stem, holds sufficient water, and allows designers to work with confidence from the first flower to the last.

That’s where Sideau®, developed by Agra-Wool International, makes all the difference.

Built for Creative Freedom

Made from natural basalt, Sideau® provides the stability and water retention needed for impressive floral creations while helping designers achieve a naturally organic look. Branches, seasonal flowers, and textured materials can be positioned exactly where they belong, allowing floral artists to build installations that feel effortless while remaining structurally secure.

Every florist knows that large installations come with challenges. Heavy stems, long design hours, transportation, and hydration all play a role in the final result.

Sideau® offers dependable support throughout the entire process. Its excellent water-holding capacity keeps flowers hydrated, while its firm yet workable structure makes it easy to create movement and depth without compromising stability.

The result is exactly what designers want: floral pieces that appear natural, abundant, and full of life.

The Story Doesn’t End After the Event

When the wedding or event has come to an end, most floral mechanics have fulfilled their purpose.

Sideau® is different. The leftover pieces still have value.

Rather than treating them as waste, they can begin an entirely new journey. Smaller pieces can be reused as part of a growing medium, providing support for seeds to germinate and for young plants to establish healthy roots. It’s a simple example of how one material can serve multiple purposes before its end of life.

A Circular Approach Rooted in Nature

The sustainability of Sideau® lies not only in its natural origin, but in what happens after its first use.

The material begins as basalt, a volcanic rock formed by nature. It is transformed into a professional floral design medium, supports floral installations of every scale, and then continues its journey as a substrate alternative for plant cultivation. From there, the remaining material can be added to the compost heap, mixed into the soil, and gradually returned to the natural environment.

Instead of becoming the end of the story, every leftover piece becomes the beginning of something new.

Sustainable Choices That Make Sense

Florists are increasingly looking for more than only beautiful designs. Clients ask questions about sustainability, environmental goals, and designers’ own values.

Choosing Sideau® means choosing a floral base that performs exceptionally during the design process while offering opportunities for responsible reuse afterward.

For large-scale floral work, that combination matters. Reliable support, excellent hydration, a naturally organic appearance, and a material that continues to contribute long after the installation has been dismantled.

Designing for Today and for Tomorrow

The most memorable floral installations don’t just leave a lasting impression on guests. They also leave a smaller footprint behind. By thinking about what to do after the event itself, florists can embrace a more circular way of working - one where creativity, craftsmanship, and sustainability go hand in hand because the best floral mechanics don’t stop working when the flowers come down. They begin their next chapter.

FAQ

Who is Sideau®?

Sideau® is perfectly suited for florists and flower arrangers who want to use a fully environmentally friendly base for their creations. Sideau® has the same use characteristics as floral foam. In contrast to floral foam, which is made from oil derivatives and phenol resin, which is plastic, Sideau® is fully natural and made of Earthwool®, a natural product made from basalt, a volcanic igneous rock.

How fast does Sideau® absorb water?

A standard Sideau block can absorb approximately 1.5 liters of water in just 1 second. It’s important not to submerge it longer than that, as over-soaking can cause surface softening. Correct hydration ensures optimal stem support and consistent performance.

What is the consists of Sideau®?

It consists of 97% basalt, a natural volcanic stone, bonded with a plant-based binder derived from sucrose (natural sugar). This means Sideau® is entirely natural and can be composted after use. The minerals in basalt enrich the soil, promoting healthy plant growth. Additionally, Sideau® is pH-neutral and free from harmful chemicals, making it suitable for use in natural cemeteries and recognized as a sustainable solution in many countries.
