Digitalization in the construction industry is no longer a future topic – it is a reality. And yet, it often falters exactly where it could make the biggest difference: in communication, documentation, and daily processes on the construction site.
While other industries have long embraced digital work, construction often still relies on the last report on the clipboard or the order on a piece of paper in the glove compartment. Many companies know: Something needs to change. But how?
One encouraging example that demonstrates how digitalization can work without a lot of technical fanfare is the construction company Müller Bau. A family business with a history – and the courage to forge new paths without reinventing the construction site. Instead of complicated software solutions, they rely on what everyone is already using: WhatsApp. But not alone; it is combined with a tool that turns spontaneous communication into genuine structure: Valoon.
Müller Bau – craftsmanship with origins, built for the future 🧱
Construction quality since 1985 – that’s what Müller Bau stands for.
What began as a dream of Walter Müller, master mason and building technician, is today a versatile construction service provider with locations in Mettendorf (DE) and Bettel (LU) – managed 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, it became a company with around 30 employees, which today realizes both classic construction, residential complexes, agricultural buildings, and complex outdoor facilities.
“You can not only build on us but with us.”
This attitude runs through all projects: Müller Bau combines tailored planning, modern technology, and precise execution – from the first shovel to the handover of keys. Whether it’s structural work, commercial buildings, or HVAC technology: here, everything is built with attention to detail, technical expertise, and creative spirit.
🤝 People at the center – with head, heart, and craftsmanship
What distinguishes Müller Bau is not just machines or materials – but the people behind them. In a people-oriented corporate culture, training, development, and long-term commitment are prioritized. This creates a strong team that works together with experience, motivation, and genuine engagement.
Whether skilled worker, apprentice, or construction management – here, everyone pulls together.
🛠️ Services that convince – all from one source
Whether it’s structural work, renovation, 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 envelope, from the commercial hall to the 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 has long been a part of daily life: agreements via WhatsApp. What has long been the norm in personal spaces has also found its firm place in trades. No other communication tool is so widespread, so simple, and so intuitive to use – whether you are a construction manager, HVAC master, or warehouse worker.
At Müller Bau, WhatsApp is used purposefully – not as a stopgap solution, but as part of a thoughtful digital workflow. Because the messenger is not only quick and practical but also can be used professionally with the right background system.
The difference: Müller Bau combines WhatsApp with Valoon – bringing structure, clarity, and security to communication.
Whether orders, measurements, or defects: What was previously noted by hand on slips of paper is now processed via WhatsApp message directly into the system – and is cleanly documented, assigned, and further processed there.
What this concretely means in everyday life will be shown in the next section – with real voices from the company.
This is how Müller Bau uses WhatsApp + Valoon in everyday work 🛠️💬
At Müller Bau, digitalization is not just a buzzword – but a lived reality. And this only works with tools that fit into the daily routine on construction sites, not against it. That’s why the team relies on what’s already there: WhatsApp.
In connection with Valoon, it becomes a smart communication channel that can do more: structuring messages, automatically assigning content to projects, capturing tasks – and documenting everything traceably.
🔧 HVAC sector: Orders via WhatsApp
“I write what I need via WhatsApp – Valoon automatically turns it into a ticket. In the warehouse, it’s prepared, and I just pick it up. Previously: paper slips. 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 way, 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 relevance and timestamp.
📦 Warehouse: Clear overview instead of paper chaos
“Previously, orders came on slips of paper or somehow via WhatsApp. Now everything runs cleanly through Valoon – structured, traceable, faster.” – Helmut Kolbet, warehouse logistics at Müller Bau
For Helmut, Valoon provides exactly what was previously missing: clarity. Orders are clearly assigned, are directly visible in the system, and can be quickly prepared. No scrolling through chats, no misunderstandings.
This ensures smooth processes – especially in stressful moments on the construction site or in the warehouse.
📁 Accounting & Documentation: Everything clearly assigned
“Measurements, reports, photos – everything comes in digitally and is immediately assigned to the right project. No more slips of paper, 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 time sheets are no longer laboriously collected – but are automatically stored in the project. This creates a complete, digital construction documentation almost incidentally.
This saves time, reduces sources of errors, and ensures maximum transparency – for accounting, project management, and later billing.
Why Müller Bau works more digitally 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, well-thought-out approach that addresses exactly where daily construction life takes place: in WhatsApp.
The secret to success? Instead of imposing new processes, Müller Bau utilizes existing tools – and enhances them with a tool made for real construction sites: Valoon.
The benefits are apparent in everyday life:
- Communication flows quickly and intuitively via WhatsApp – without training or app compulsion.
- Valoon ensures structure, documentation, and assignment.
- Information no longer gets lost,but ends up exactly where it is needed.
- Office and construction site come closer together – in real time, without additional effort.
Digitalization doesn’t have to be complicated. It must work.
Müller Bau shows that real digital transformation does not begin with hardware but with the mindset: Those who are open to new paths 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 that are 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 becomes clear: WhatsApp in construction is already a reality. The messenger facilitates quick communication, is easy to use, and is already in use by all employees.
But it is only through the connection with Valoon that it becomes a true digital tool:
- Information is organized,
- processes standardized,
- documentation automated,
- and everyday life on the construction site sustainably simplified.
Müller Bau proves that digitalization does not have to be expensive, cumbersome, or technology-heavy. On the contrary: when existing tools are cleverly supplemented, it results in a solution that truly works – for all involved.
WhatsApp remains. Valoon makes it better.
