Research, development
and innovation
We design solutions to create new effects tailored to each space.
Our designs model the architecture of the cities and special spaces
We apply the constant improvement of our systems, cultivating the innovation and knowledge acquired thanks to more than 90 years’ experience in the world of ornamental fountains and illumination.
The innovation processes we carry out at OTB’s testing bench allow us to create value with our products and processes, and improve the existing ones, thus achieving a clear competitive advantage.
It was in 1925 that engineer Carlos Buigas began to create the first ornamental fountains and water, light and sound shows, which began our research, development and innovation process, always at the forefront of this field.
Since then and to date, our company has been developing specific systems and equipment to offer our clients unlimited possibilities in ornamental fountains and illumination, which guarantee great durability, a low level of maintenance and a unique sensory experience.
