Our own machinery and equipment
A modern fleet — predictable delivery
We build in five counties

- Komárom-Esztergom
- Fejér
- Veszprém
- Vas
From our depots in Győr and Győrújbarát we serve the whole of Western and Central Transdanubia. Short mobilisation times combined with our own machinery let us reach the site quickly and carry out the works to schedule, with a continuous presence.

A modern fleet. Independent delivery capacity.
High-quality water utility construction calls for a solid technical background and reliable machinery. Our extensive equipment base, operated from the depots in Győr and Győrújbarát, allows us to deliver complex works largely from our own capacity, predictably and efficiently.
Our fleet — from tracked and wheeled excavators, tractors and mini excavators to truck-mounted cranes — provides the mechanical backing for large-volume earthworks and utility construction.
Our specialised technology includes precision pipe and rotating lasers, pneumatic road boring equipment, compaction and cutting machines and high-capacity pumps.
Our own machinery and equipment provide a firm technical basis for the full construction and reconstruction of drinking water and sewer networks and the related civil engineering works; we also hold the special machines and tools needed for the proper maintenance and care of green areas.
More than 35 years of results in figures.
We have been working in civil engineering and water utility construction for more than 35 years. In that time we have gained experience in hundreds of projects, hundreds of kilometres of completed utility networks and countless successfully solved technical tasks. Behind our results lie several decades of professional knowledge and work delivered.
Stable cooperation,
a strong professional base.
Partnerships built over many years contribute to our company's development, its reliable operation and its successful projects.

What quality management system do you work to?
Our activities are carried out under a quality management system compliant with MSZ EN ISO 9001:2015. This ensures the effectiveness, continuous improvement and verifiability of our defined work processes. The certificate is made available when we quote.
What should I send with a request for quotation?
We can give a meaningful quotation fastest if we receive the project location, the technical scope or the design documentation (route, diameters, material grade, length), the planned start and the required completion date. If the investment is still at preparation stage, a short description and a phone call are enough for an indication of magnitude.
How does the first contact work?
You can reach us through the quotation form, by e-mail (iroda@thermin.hu) or by phone (+36 30 953 5364). For technical questions our colleagues are available at thermin@thermin.hu. Once your enquiry arrives we discuss the technical scope, with a site visit where needed.
Planning an investment?
Send us the technical scope or the design documentation, and we will come back with an individual quotation and a realistic schedule. We work both as main contractor and as subcontractor.
