Mr. Kox, what does a typical workday look like for you?

Our day starts at 7:30 a.m. with a team meeting at the company. Since we’ve digitized our workflows, all employees receive the relevant information for the next workday via a special app the evening before. While the teams head out to their respective construction sites, I coordinate ongoing projects, handle correspondence and coordinate with our office.

I also regularly visit the construction sites in person to exchange ideas with my employees and our customers. This personal presence is indispensable. It’s the only way to find optimal solutions together.

What challenges do you face in your profession?

The most demanding task is often an accurate diagnosis of the problem. Where exactly is the moisture penetrating? What is the customer's goal with the renovation: is it simply to dry out a basement for storage purposes or is high-quality living space to be created? Since architects or planners are often not involved, we take on this advisory role ourselves. That requires in-depth technical expertise. Additionally, every step of the work must be executed perfectly to achieve a lasting solution – whether it’s basement waterproofing, balcony refurbishment or repairing underground garages.

What personally motivates you in your daily work?

I see myself as a problem solver– and I do it with great passion. When people suffer from moisture damage or mold in their homes and it affects their quality of life, we can offer concrete help. It goes far beyond craftsmanship. It's about real responsibility for our customers' well-being.

I still find my job exciting because it’s so diverse: You need solid technical understanding and practical skills, you have daily contact with customers, and every day brings new challenges.

What do you particularly value about working with MC-Bauchemie?

The personal and collaborative support from MC-Bauchemie is something special and clearly sets them apart from other providers. I have a close, direct relationship with my contact person and can call him anytime to discuss an issue. At MC, you’re not just a number – you experience real partnership and work on the same level. This reliability is not a given in our industry.

The specialized training courses are also especially valuable, such as those on injection techniques. In the past, we avoided injection work due to a lack of expertise. Thanks to MC's training, these demanding methods are now part of our standard repertoire and open new business areas for us.

How do you view the future prospects for building protection?

I’m extremely optimistic. The steadily rising cost of new construction makes existing properties increasingly attractive – but many of these buildings require extensive renovation. There’s especially a huge need for improvement in waterproofing and building protection, whether for balcony refurbishments or repairing underground garages.

At the same time, our profession comes with physical demands, and we are also affected by the general shortage of skilled workers. Nevertheless, building protection offers a secure career path: While modern technology can replace many things, mortar and sealing materials still have to be applied on-site by qualified professionals.
