The human right to housing is more than 4 walls and a roof. It is also the right of protection from cold and heat, now and in the future. Heating, cooling, domestic and potable water should be available anytime, anywhere. At the heart of that protection lies an efficient underground distribution system. But how can we secure a reliable and efficient supply to maximize our use of energy at minimal financial, environmental and infrastructural cost?

Safety first – for people, and environment!

Installing new pipelines in congested ground conditions can be a difficult challenge for designers and installers. There is a lot of pressure to do this quickly, yet effectively, with minimal disruptions to surroundings and building structures. Regulations also increasingly require these installations to be durable.

The good news is; we can help! Together with leading energy and water suppliers we have developed flexible maintenance-free solutions that are safe and sustainable, yet fast to implement, ensuring an efficient supply for generations to come. We tailor our solutions to all needs and conditions; space restrictions and difficult ground conditions are our bread and butter!

We co-operate with traditional owners as well as new investors to implement fast, reliable and sustainable network solutions for all types of projects with minimal disturbance and optimal benefits for our stakeholders.

Sustainability is key

That's our ambition. A durable design to secure valuable living for now and generations to come is the reason why. We hold ourselves responsible for the future and strive for a circular economy - our systems are perfectly attuned to those values.

We know how

We have over 30 years of experience implementing our systems in all types of conditions, each with its own challenges. As we keep close to our stakeholders, it gives us the opportunity to understand the real challenges that need to be solved.

Take a hotel resort that wants to ensure the best satisfaction for their guests. That requires an infrastructure that works safely under all different load conditions, for both heating and cooling. A hospital has to provide the highest health standards in their systems - at all times. A city needs reliable  heating in harsh winters to keep its citizens alive.

We are faced with these crucial challenges everywhere around the world. 

Ask our specialists how we can answer to your needs. With our full support in every step of the way, from engineering to the final pressure tests, we make sure you realize your goals.
