Your Drilling Company in Northern Germany Since 1900
The specialists in site investigations, deep foundations, and well construction
Get your project off the ground as quickly as possible—our experienced team will handle it professionally and efficiently!
There is a lot to consider before work begins on-site: We obtain permits, have structural analyses prepared, schedule staff, materials, and equipment, and coordinate transportation and subcontractor services.
Cost Transparency – So You Always Know What You're Paying For!
We all know that unexpected costs can quickly pile up during construction. At THADE GERDES, we help minimize these costs from the outset.
A specific schedule that we’ll stick to—no matter what!
Our experienced project managers oversee all trades to ensure that your project is completed by the agreed-upon deadline.
We're not afraid to tackle construction sites with limited space and challenging ground conditions!
With a highly qualified team, specialized machinery, and more than 120 years of experience, we are drilling experts who are equally at home on land and at sea.

3 Avoidable Problems That Occur in Many Construction Projects
1. You can't find the right partner for your project
Are you looking to make your dream of homeownership a reality, or are you planning a major infrastructure project? Often, builders don’t receive any quotes or responses to their inquiries!
→ As one of the most renowned drilling companies in northern Germany, we’re here to handle your project! From small residential construction projects to large-scale public infrastructure contracts, we’re your go-to partner. Just reach out to us and find out right away if and when we can get started!
2. Skyrocketing Construction Costs
Every project manager's worst nightmare: construction costs that spiral out of control!
Unfortunately, this happens more often than you might think, especially when the work isn't well-planned and professionally executed.
3. Orders take forever
The project is off to a great start! Then one delay follows another…
- Permits are not obtained in a timely manner
- Contractors do not arrive at the agreed-upon time
- Equipment is currently unavailable
THADE GERDES is putting an end to it!
→ Experienced project managers will handle your drilling project—good planning is the foundation for ensuring your project is not only successful but also completed quickly and cost-effectively.
→ Some of our machines are custom-built special-purpose machines, some of which weigh only half as much as standard machines on the market. This means we don’t need special permits for transport—and that saves you time and money!
→ From daily reports to fieldwork documentation: A lot of paperwork takes a lot of time. At THADE GERDES, you’ll receive documents quickly and in a clear, organized format because we work digitally—which means less paperwork for you, us, and all the trades involved!
Whether it's a private or public project: Here's how THADE GERDES ensures customer satisfaction
