Digitalization in the construction industry is no longer a topic for the future – it is a reality. And yet, it often falters exactly where it could make the biggest difference: in communication, documentation, and daily operations on the construction site.
While other industries have long been working digitally, the construction sector still often relies on the last report on the clipboard or the order on a piece of paper in the glove compartment. Many companies know: Something must change. But how?
An example that is encouraging and shows how digitalization can work without much technical fuss is the construction company Müller Bau. A family business with history – and the courage to forge new paths without reinventing the construction site. Instead of complicated software solutions, they rely on what everyone already uses: WhatsApp. But not alone; they combine it with a tool that transforms spontaneous communication into real structure: Valoon.
Müller Bau – craftsmanship with heritage, built for the future 🧱
Construction quality since 1985 – that’s what Müller Bau stands for.
What started as a dream of Walter Müller, master bricklayer and civil engineering technician, has today become a versatile construction service provider with locations in Mettendorf (DE) and Bettel (LU) – led in the second generation by Rainer Müller.
The story began in Sinspelt, Rhineland-Palatinate, where father and son built the family business together. From a two-man team, the company has grown to about 30 employees, delivering both traditional construction, residential complexes, agricultural buildings, and complex outdoor facilities.
“You can not only build on us but also with us.”
This attitude permeates all projects: Müller Bau combines tailor-made planning, modern technology, and precise execution – from the first groundbreaking to the handover of the keys. Whether it’s new construction, commercial buildings, or HVAC technology: here, attention to detail, technical expertise, and creative spirit are paramount.
🤝 People at the center – with head, heart, and craftsmanship
What distinguishes Müller Bau is not just machinery or materials – but the people behind them. In an employee-oriented corporate culture, people are trained, promoted, and retained for the long term. This creates a strong team that collaborates with experience, motivation, and genuine commitment.
Whether skilled worker, apprentice, or construction management – here, everyone pulls together.
🛠️ Services that convince – from a single source
Whether new builds, renovations, outdoor facilities, or HVAC technology – Müller Bau offers a diverse range of services for projects of all sizes. From the foundation to the completed building shell, from the commercial hall to a precisely paved driveway: everything comes from one source – expertly, reliably, and thoughtfully.

WhatsApp in construction – the familiar tool becomes a digital lever 📲
On many construction sites, it’s already common practice: agreements via WhatsApp. What is standard in private life has also found its firm place in craftsmanship. No other communication tool is as widespread, simple, and intuitive to use – whether construction manager, HVAC master, or warehouse staff.
At Müller Bau, WhatsApp is used purposefully – not as a stopgap, but as part of a well-thought-out digital workflow. Because the messenger is not only fast and practical but can also be used professionally with the right system in the background.
The difference: Müller Bau combines WhatsApp with Valoon – bringing structure, clarity, and security to communication.
Whether orders, measurements, or defects: what was once recorded by hand on notes is now processed via WhatsApp messages directly into the system – where it is neatly documented, assigned, and further processed.
What this means in practice, we will show you in the next section – with genuine voices from the company.
How Müller Bau uses WhatsApp + Valoon in daily operations 🛠️💬
At Müller Bau, digitalization is no buzzword – it’s a lived reality. And this only works with tools that integrate into the everyday life of the construction site rather than complicating it. That’s why the team relies on what’s already there: WhatsApp.
In conjunction with Valoon, this becomes a smart communication channel that can do more: structure messages, automatically assign content to projects, record tasks – and document everything traceably.
🔧 HVAC area: Orders via WhatsApp
“I write via WhatsApp what I need – Valoon automatically turns this into a ticket. In the warehouse, it’s prepared, and I just pick it up. Earlier: paper. Today: digital.” – Mathew Schlöder, HVAC Master at Müller Bau
Mathew uses WhatsApp to quickly and easily order materials – directly from the construction site. Valoon processes the message in the background and creates a ticket in the system. This means the order goes directly to the warehouse – without follow-up questions, without paper.
This not only saves time but also ensures that every order is documented and traceable – with project reference and timestamp.
📦 Warehouse: Clear overview instead of paper chaos
“Previously, orders came on notes or somehow through WhatsApp. Now everything runs smoothly through Valoon – structured, transparent, and faster.” – Helmut Kolbet, Warehouse Logistics at Müller Bau
For Helmut, Valoon provides exactly what has been missing: overview. Orders are clearly assigned, visible in the system, and can be prepared quickly. No scrolling through chats, no misunderstandings.
This ensures smooth operations – especially in stressful moments on the construction site or in the warehouse.
📁 Accounting & Documentation: Everything neatly assigned
“Measurements, reports, photos – everything comes in digitally and is immediately assigned to the correct project. No more notes, no chaos.” – Jutta Hermann, Payroll and Financial Accounting at Müller Bau
Even in the office, the connection between WhatsApp and Valoon pays off. Photos from the construction site, reports, or timesheets are no longer collected painstakingly – but are automatically stored in the project. This creates a complete, digital construction documentation along the way.
This saves time, reduces sources of error, and ensures maximum transparency – for accounting, project management, and later billing.
Why Müller Bau works digitally more than many others – and what others can learn from it 💡
Many construction companies talk about digitalization – Müller Bau lives it. Not with complicated software or elaborate IT projects, but with a simple, thoughtful approach that targets where the construction site reality occurs: on WhatsApp.
The secret to success? Instead of imposing new processes, Müller Bau utilizes existing tools – and extends them with a tool that is truly designed for construction sites: Valoon.
The benefits are evident in daily operations:
- Communication runs quickly and intuitively via WhatsApp – without training or app enforcement.
- Valoon provides structure, documentation, and assignment in the background.
- Information no longer gets lost,but lands exactly where it is needed.
- Office and construction site come closer together – in real-time, without extra effort.
Digitalization doesn’t have to be complicated. It must work.
Müller Bau shows that true digital transformation doesn’t start with hardware but with mindset: those who are open to new ways while understanding the reality on the construction site can achieve great things with small steps.
And that’s what makes Müller Bau a role model – for many other companies ready to take the next step.
More than just chat: what Müller Bau really achieves with WhatsApp.
Whether HVAC master, warehouse logistics, or construction management – at Müller Bau, it’s evident: WhatsApp in construction is already a reality. The messenger ensures fast communication, is easy to use, and is indeed in use by all employees.
But only through the connection with Valoon does it become a true digital tool:
- Information is organized,
- processes are standardized,
- documentation is automated,
- and everyday life on the construction site is sustainably facilitated.
Müller Bau proves that digitalization doesn’t have to be expensive, complicated, or tech-heavy. On the contrary: when existing tools are cleverly complemented, a solution emerges that truly works – for all stakeholders.
WhatsApp remains. Valoon makes it better.
