The basis of almost every construction project is a reliable and complete knowledge of the subsoil conditions. Our external teams ensure that you as the client receive this information – quickly, flexibly and precisely. With six experienced specialists, divided into three high-performance teams, field surveys can be carried out at several locations at the same time. This means that even complex and time-critical construction projects can be efficiently supervised without compromising the quality of the results.

We combine manual probing equipment for confined or hard-to-reach areas with our powerful probing crawler (MRZB) for more extensive exploration campaigns or challenging underground conditions. This technical diversity makes it possible to precisely sink ram core soundings up to approx. 14 m and ram soundings to approx. 20 m depth. Material samples are taken layer by layer, carefully documented digitally and subjected to an initial geotechnical assessment (“soil address”) on site.

The work of our exploratory teams is characterized by a high degree of flexibility. Depending on the local situation, we choose the appropriate method and procedure to carry out the necessary information and obtain the necessary information – whether in a confined space with handheld devices or over a large area and mechanically with the MRZB probing caterpillar. This adaptability makes it possible to deliver results in a timely and cost-efficient manner without sacrificing accuracy and quality.

Digital documentation and seamless data chain

The direct integration with the company’s own soil mechanics laboratory creates a continuous data chain: reliable, project-specific information is generated from qualified sampling to initial assessment in the field to engineering evaluation and evaluation.

Your advantages in the course of the project:

  • Short response times due to close integration of field and laboratory
  • Carefully digitally documented and traceable results
  • Uniform database for building owners, planners and surveyors
  • Efficient processes even in the event of short-term changes to plans

Our customers benefit from well-founded results and practical solutions that enable safe planning and implementation of construction projects.

From exploration to recommendation – geotechnical expertise with added value

Based on the data obtained, the experts from TABERG Ingenieure GmbH – a member of the SIERA Alliance provide detailed information and recommendations on:

  • Type and dimensioning of the foundation
  • Suitable measures for the remediation of contaminated sites
  • Possible disposal and recycling routes of surplus soil

In this way, potential risks can be identified at an early stage, costs can be reliably calculated and costly changes during the construction phase can be avoided.

Our exploratory teams not only provide data, but also decision-relevant information that flows directly into project planning. Whether building owner, planner or expert – all parties involved receive a solid basis on which they can make safe, economical and practical decisions.

Key figures at a glance

  • 3 operational exploratory teams
  • 6 experienced professionals
  • approx. 14 m maximum depth for ram core soundings
  • approx. 20 m maximum depth for pile driving soundings
  • Consistent digital documentation and complete traceability

Conclusion & Call to Action

A Message from the Founder: Florian von Tucher

In the mid-2000s my involvement in development aid took me to some of the most remote and impoverished regions of the world. 

Northern Tibet, Mongolia, and Western China – where I was involved with the implementation of decentralised wastewater treatment systems, I realised I needed a deeper purpose. Though I later found success in real estate development, the desire to make a lasting impact never left me.  

A pivotal moment occurred when I was invited to Ghana by my friend and mentor, Cardinal Peter Turkson, who was the head of the Dicastery for the Promotion of Integral Human Development of the Catholic Church at the time. He has since been appointed the Pontifical Chancellor of the Academy of Sciences and the Pontifical Chancellor of Social Sciences.  

Cardinal Turkson had a profound influence on me. His invitation gave me the opportunity to witness firsthand the development needs of the country. We reflected on my experiences in China, and together, we envisioned a model of development that would take root in one community and gradually expand. We believed that small, strategic steps could lead to lasting transformation – just like the biblical parable of the mustard seed, which grows into something far greater than its humble beginnings. 

Cardinal Turkson’s steadfast belief in this vision and encouragement became the base upon which the Mustard Seed Foundation was built. His unwavering support, wisdom, and guidance helped shape not just the mission of the Foundation, but my personal journey as well. 

With the encouragement of the Cardinal and the Integral Human Development (IHD) office, we initially operated with the IHD before establishing the Mustard Seed Foundation as a stand-alone organisation in Germany. We have been fortunate to receive support from numerous European donors, a humble reminder that our mission is not just about individual efforts – it is about collective impact. 

Collaboration has been a cornerstone of our work. We have partnered with organisations like Caritas and Rotary International to extend our reach. One of our most impactful collaborations has been with M&P Group, who donate their engineering concepts, project supervision, and high-quality technical execution, allowing 100% of donor contributions to go into the projects themselves. 

One such initiative is the Clean Water Initiative, launched in partnership with M&P Group. In 2024, we completed a well in Ndoss, Senegal, significantly improving agricultural efficiency and empowering the local community. This project epitomises our commitment to sustainable solutions – starting with clean water and gradually building infrastructure that supports long-term development. 

Our work aligns closely with the United Nations Sustainable Development Goals (SDGs), focusing on poverty alleviation, economic empowerment, environmental sustainability, and humanitarian aid. Our model is simple but effective: start with one project and expand, year by year, to create an ecosystem of support. A water well leads to a school, which leads to renewable energy solutions, which, in turn, fosters economic opportunities. Over time, these efforts cumulatively transform entire regions. 

The Mustard Seed Foundation is a testament to what can be achieved with nothing more than a vision, a strong commitment, and the faith of a mustard seed. Yet, none of this would have been possible without the belief and encouragement of Cardinal Peter Turkson. His unwavering faith in our mission gave me the courage to persevere through challenges and continue expanding our impact. As we continue our work, we remain driven by the belief that small beginnings can yield great outcomes, inspiring hope and lasting change in the communities we serve. His legacy of faith, vision, and commitment to human dignity is deeply woven into every initiative we undertake.
