F. Willich's solutions support construction projects where protection, durability, and technical expertise are essential. 

We ensure that structures are reliably shielded from external influences, save energy, and remain stable in the long term. We also ensure that existing pipe networks continue to function and that damage underground is repaired safely and sustainably, precisely, cleanly, and using state-of-the-art technology.

Surfaces also benefit from our systems: they become resistant to all kinds of stress and retain their quality even with intensive use. And when the going gets tough – underground, in tunnels or in complex soil structures – we offer special materials that create stability, secure cavities and make structures sustainable in the long term.

The result is a complete package that provides noticeable relief in practice: less risk, more safety, and solutions that make everyday life on the construction site easier while increasing the service life of structures.
