The story of Kwantz

Kwantz Atelier 73

Kwantz was founded in 2016 by Jeroen Dils, as a spin-off from Ghent University. After years of specialised research on ultra-High Performance Concrete (UHPC), he realised his dream of marketing this material as a high-quality concrete for interior applications. After all, the concrete he developed is a fusion of technology and beauty, since these concrete slabs can be manufactured without fibers and/or reinforcement. This means that concrete is now also accessible as a material for kitchens and bathrooms.

Sister Steffi strengthened the team in 2019, where she is responsible for marketing. As a Belgian family business, Kwantz is committed to a sustainable concrete production. Moreover, Kwantz uses mainly components from Belgian soil and no synthetic products are added.

In the same year, Kwantz starts its next chapter together with the Willy Naessens group. Now they are ready to develop a full-fledged concrete production facility in Wortegem-Petegem.

Our mission

We create your stone

We are passionate about creation.
Our concrete differentiates itself technically by its extreme strength, which allows us to make thin slabs. A sleek design is what we stand for.

We want to create concrete that above all is beautiful. Composed of mineral components and plastic-free. The result? A natural stone with smooth tones and subtle shades of concrete.

We strive for constant improvement
Daring, curious and very eager.

Kwantz wants to offer sustainable concrete slabs for interior use. That's why we continuously adjust our concrete composition, so we can produce more and more ecologically, now and in the future. 

For our concrete production, we only use naturally available materials such as clay, limestone and quartz, mostly from Belgium. 

Furthermore, we consciously choose not to add plastics to our concrete.

The concrete that Kwantz produces gets its extreme strength from the low water content, among other things. This way the consumption of fresh water is minimised.

The waste streams generated during the concrete production are limited and recovered as much as possible
