Completed Projects
For more than 60 years, Klefenz has been serving civil engineering and creating the foundation that keeps mobility running reliably every day. As a family-run company with a strong tradition and a clear view ahead, we combine precision, durability and a spirit of innovation to create routes that connect people, opportunities and the future.
While others talk about sustainability, we put it into practice. With our own gravel pit and our own recycling yard, we close the material cycle where it actually begins: on the construction site. Excavated material is processed, mineral construction waste is reused, and transport routes remain short.
This is not a marketing concept, but established practice – and has been part of our value creation for decades.
A family-owned company with flat hierarchies, short decision-making paths and a management team that knows every employee by name. These structures have grown over decades and continue to shape everyday work – on the construction site, in the office and across the machinery fleet. The result: a company where colleagues stay for the long term and responsibility is passed on from generation to generation.
Anyone building for Deutsche Bahn, energy providers and municipalities must be able to prove their qualifications – not merely claim them. Klefenz is DB-prequalified, ECM-certified in accordance with EU Regulation 2019/779 and audited in all relevant areas of our service portfolio. These credentials are a prerequisite for every tender. For our clients, they are proof that we deliver what we promise.
Whether it is a demanding construction project or a professional perspective – Klefenz stands for experience, reliable collaboration and a clear commitment to quality. If you would like to realise a project or become part of our company, we look forward to speaking with you and taking the next step together.
