Innovation, progress and sustainability require an awareness of the past, a present in harmony with needs and a vision for the future. We rely on modern technologies and sustainable cooperation with nature.
Ideas and solutions emerge when the focus is on transparent communication and an open exchange. This applies both to our team and to the collaboration between us and our customers.

Environment
We focus on the construction of natural pools and prefer chemical-free water treatment. We use the Living Pool technology from Biotop to ensure natural water purification. This technology reduces the need for chemical additives and offers an environmentally friendly alternative to conventional chlorine pools or pools with salt electrolysis.
We attach great importance to the proper separation of waste on all our construction sites. By consistently separating and recycling waste, we minimize the environmental impact and promote the recycling of materials. To this end, we provide a waste disposal system on every major construction site.
We have been operating a solar system with a capacity of 250 kWh on the roof of our building since 2024. This measure supports our sustainability goals and promotes the use of renewable energies.

Quality & Development
To ensure that our operational processes are optimized and meet international standards, we have opted for ISO certification. This ensures our commitment to outstanding quality and environmental responsibility.

ISO 14001:2015 is a globally recognized standard for environmental management systems that focuses on minimizing environmental impacts and improving environmental performance. To this end, we have implemented an environmental management system designed to identify, monitor, control and continuously improve environmental impacts. In doing so, we focus on using resources efficiently and developing sustainably. With ISO 9001:2015 certification, we ensure professional quality management.
