In the previous article, we discussed how to choose the right team for water drilling. Today, we focus on geotechnical drilling and exploration drilling. If last time we talked about capturing and using an aquifer in order to obtain water, this time we are looking at soil investigation and analysis, as well as the identification of valuable underground resources.
This article is especially relevant for:
- real estate developers, construction companies, and infrastructure contractors who need detailed soil information before starting a project — through geotechnical drilling;
- mining, energy, oil, and natural resource companies that aim to identify underground resources — through exploration drilling.
Read on and discover everything you need to know about these types of professional geological drilling works.
What Are Exploration and Geotechnical Drilling Works, and Why Are They Important?
Geotechnical drilling – the foundation of every safe project
Geotechnical drilling consists of soil investigation works carried out before construction. It involves collecting soil and rock samples from various depths, testing them in the laboratory, and interpreting the results in order to determine:
- the bearing capacity of the ground (how much load the soil can safely support);
- soil stability and long-term behavior;
- relevant geotechnical properties for design, such as moisture, compressibility, consistency, and more.
These investigations are essential when building roads, bridges, large buildings, or any other type of structure, because structural safety depends directly on foundation quality.
Exploration drilling – discovering hidden resources
Exploration drilling aims to identify underground resources such as water, minerals, gas, oil, or geothermal energy. It is especially used by mining companies, energy operators, and natural resource businesses, helping them determine the economic viability of an extraction project.
How Is a Professional Drilling Project Carried Out in Practice?
A professional geotechnical and exploration drilling project in Romania normally includes three main stages:
I) Planning and data collection stage
Every project begins with desk analysis. At this stage, the specialist team gathers information about the target area: geological maps, historical data, climatic conditions, and existing reports. Based on this information, they define:
- the exact drilling points and target depths;
- the equipment and technical methods to be used;
- the clear objectives of the investigation, whether geotechnical or exploration-related.
Proper planning means fewer unnecessary drillings, optimized costs, and much clearer results for both designers and investors.
II) Drilling execution with specialized equipment
Once the plan is established, the practical fieldwork begins. It is important for the team to use modern technology, both for data accuracy and for reducing execution time.
Dromcons continues to invest in state-of-the-art equipment, strengthening its position as a trusted partner in infrastructure and geotechnical studies. One example is the integration of the Massenza Drilling Rig MI5, which is more powerful and more versatile than previous models.
Thanks to its extended drilling capabilities, the MI5 can reach greater depths and support a wide range of applications:
- water wells;
- geotechnical studies and investigation drilling;
- foundation drilling and complex infrastructure works;
- special projects in areas with difficult geological conditions.
III) Sample analysis and geotechnical report
After sampling, the materials are sent to the laboratory. At Dromcons, tests are performed in our own laboratory, where we carry out both geotechnical testing and tests for fresh and hardened concrete. Based on the results, the team prepares the geotechnical study — an essential technical document that:
- details soil properties and stratification structure;
- includes recommendations for the type and dimensions of the foundation;
- provides data for evaluating geotechnical risks.
This report becomes the basis for structural design and for future investment decisions.
What Types of Resources and Information Can Be Identified Through Exploration Drilling?
Through exploration drilling, specialists can identify:
- groundwater – essential for industrial projects, agriculture, or community water supply;
- mineral deposits and geothermal resources – used in the energy sector and construction field;
- soil and rock layers with geological relevance – important information for design decisions and environmental protection.
All of this data helps determine exploitable volume, economic profitability, and the most suitable extraction or development technologies.
Practical Applications of Geotechnical Drilling for Companies and Developers
1. Infrastructure: roads, bridges, bypass routes
Before pouring the first cubic meter of concrete, you need to know exactly what kind of soil is under the site. Geotechnical investigations identify risk areas — compressible soils, landslides, shallow groundwater levels — and make it possible to design safe foundation solutions.
2. Civil and industrial construction
For multi-storey buildings, industrial halls, or logistics centers, geotechnical data is essential for the correct design of foundations. This reduces the risk of differential settlements, cracks, or costly future consolidations.
3. Agriculture and irrigation
For irrigation projects, exploration drilling makes it possible to identify groundwater sources, evaluate water quality, and properly size pumping systems. Farmers and agricultural businesses can therefore plan sustainable and efficient investments.
4. Industrial projects and mining operations
In the mining industry, geological exploration drilling determines whether a deposit is viable. The data obtained indicates the volume, quality, and position of the resource, helping companies optimize investments and comply with environmental regulations.

Conclusions
In short:
- Geotechnical drilling investigates soil structure and properties before construction and forms the basis of a safe foundation.
- Exploration drilling identifies underground resources — water, minerals, oil, gas, geothermal energy — and helps determine the economic viability of a project.
If you are preparing a road, bridge, industrial hall, residential complex, or resource extraction project, the correct first step is a well-planned geotechnical study and, when necessary, exploration drilling.
