Who are we?
At Lajta-Duna Építő és Vízszigetelő Kft., our goal is to provide clients with professional waterproofing and thermal insulation solutions. Our company is built on expertise gained abroad in the early 2000s, and we established our headquarters in Mosonmagyaróvár in 2008 with the aim of delivering outstanding quality in the industry.
Thanks to our expertise, flexibility, and precise execution, we have become a leading waterproofing company in the Western Transdanubia region. Responding to market demands, we have expanded our activities and now carry out the construction of steel structures, roofing and façade cladding with our in-house professionals – offering smoother and more cost-effective solutions for our clients. We are equally at home in industrial halls, family and apartment building insulation, as well as in hall construction and steel structure manufacturing.
Our infrastructure enables us to execute complete design, assembly, and manufacturing processes, including necessary testing and optimization. Steel structure production has become one of our most significant sectors, which we continuously support with development and research activities.
Three principles we build on.
Qualified, dedicated professionals
Our team members carry out their work with experience and professional commitment. Continuous development is important to us, which is why we regularly participate in training, professional conferences, and material specification courses to always be up-to-date and ready to serve our clients.
Premium materials
We only work with certified materials and maintain relationships with multiple suppliers to ensure the best solutions at competitive prices. The materials we use are of certified quality and, with proper installation, guarantee long-term, flawless performance.
Fair, transparent work practices
It is fundamental for us that the work we perform meets expectations, is durable, and precise. We uphold the quality standards typical in Austria here in Hungary, whether it involves insulation, hall construction, or steel structure manufacturing.
Our company is verifiable, free from public debt, and holds the EN 1090-2 EXC-2, ISO 3834-2 and ISO 9001 certifications, proving our commitment to quality. We offer a 5–15 year warranty on our work, and modern waterproofing membranes provide reliable protection for up to 25–30 years.
