From water to free energy – how drilling can transform your project

Boreholes are solutions that connect us directly to underground resources, supplying water and energy to various projects while also providing valuable information about soil composition.
In previous articles, we have discussed separately several types of boreholes:

• Water wells
• Geotechnical and exploration boreholes
• Geothermal heating through boreholes

Now it’s time to bring them all together to get the big picture. Keep reading this article to learn everything you need to know about each type of professional drilling service.

Water Wells – The Reliable Source for Project Supply

Water wells involve drilling through the soil to reach underground aquifers, from which water can be extracted. They are used in both rural and urban settings to supply homes, guesthouses, farms, as well as industrial units or public institutions.

Benefits and examples of water wells

• Independence from the public network – for example, a vegetable farm can have its own irrigation source without being affected by seasonal restrictions.
• Reduced long-term costs – a guesthouse, for instance, can save thousands of lei annually on water bills.
• Controlled water quality – water is tested and filtered according to standards, making it suitable for food production.

Exploration Boreholes – The Key to Uncovering Hidden Resources

These boreholes are carried out to identify and evaluate mineral resources, hydrocarbon deposits, or other natural resources. They are used in mining, the energy industry, or in land assessments for major investments.

Benefits and examples of exploration boreholes

• Identifying the economic potential of land – for example, such drilling can be done before purchasing land for mining exploitation.
• Reducing investment risks – an energy company can determine exactly what resources are available.
• Efficient planning – with exploration drilling, a developer will know what natural resources can be harnessed in the area.

Geotechnical Boreholes – Soil Investigation and Analysis

Geotechnical boreholes are executed to analyze soil composition and stability. The information obtained is crucial for the correct design of any construction, whether it is a building, road, or bridge.

Benefits and examples of geotechnical boreholes

• Preventing structural issues – for example, a building erected on unstable ground may develop cracks if no preventive measures are taken. This is why geotechnical drilling is carried out before construction to determine the best foundation solution.
• Choosing the right foundation – when building a bridge, drilling helps determine whether micropiles are necessary.
• Compliance with regulations – geotechnical studies are legally required for most large-scale projects.

Geothermal Boreholes – A Sustainable and Eco-Friendly Solution

Geothermal boreholes tap into the thermal energy stored underground. Through heat pumps, this energy can be used for heating and cooling buildings at very low operating costs.

Benefits and examples of geothermal boreholes

• Cost reduction of up to 60% – for example, an office building that usually pays around 10,000 lei/month for gas can cut costs to 3,000–4,000 lei with geothermal systems.
• Eco-friendly solution – zero direct CO₂ emissions, environmentally friendly buildings.
• Constant operation – geothermal energy is available year-round, regardless of the season.

Micropile Boreholes – The Foundation for Durable Constructions

Micropiles are small-diameter foundation elements inserted into the ground to provide additional stability to constructions, especially in areas with unstable soil.

Benefits and examples of micropile boreholes

• Increased foundation strength – a bridge built on slippery terrain will last longer.
• Durability – they reduce structural maintenance costs. For example, micropiles can be extremely useful for reinforcing historical buildings.

How Can Drilling Change Your Project?

Risk reduction
Geotechnical boreholes identify soil problems early, preventing accidents and additional costs. Exploration boreholes eliminate uncertainties about resources, while micropile boreholes reduce the risk of collapse or subsidence.

Time and cost savings
A geothermal borehole can cut heating and cooling costs by up to 60%, while a water well can completely remove public network water supply costs.

Possibility to integrate multiple solutions (water + energy)
A residential or industrial project can include both a water well and geothermal drilling, achieving independence in both energy and water supply.

Case Studies – Dromcons Professional Boreholes

Arad East Bypass – Strategic Road Infrastructure
The “Design and Execution – Arad East Bypass” project, carried out in partnership with SC PORR Construct SRL and for the beneficiaries Arad County Council and C.N.A.I.R via D.R.D.P Timișoara, was a regionally significant work designed to streamline traffic and reduce pollution in the urban area.

Technical details:

• Road length: approx. 11 km
• 7 major intersections and complex auxiliary works
• 75 geotechnical boreholes drilled at various depths adapted to the specific terrain
• Detailed topographic surveys for precise road and intersection alignment
• Timely obtaining of permits and authorizations, avoiding administrative delays

Our geotechnical analysis allowed the project to be adapted to real ground conditions, optimizing construction costs and avoiding potential structural problems.

Oradea Metropolitan Ring Road – Modern Connectivity Between Localities
The “Design and Execution – Oradea Metropolitan Ring Road, Lot 2: KM 9+055 - KM 17+017” project, also in collaboration with SC PORR Construct SRL and the Bihor County Council, was a major step in developing metropolitan infrastructure, facilitating quick connections between Oradea and neighboring towns.

Technical details:

• Road length: approx. 8 km
• 3 new intersections for traffic distribution
• 51 geotechnical boreholes drilled to depths of up to 25 meters to determine soil composition and bearing capacity
• Advanced topographic studies using modern scanning and measurement technologies
• Complete laboratory services for soil and water sample analysis

The collected data allowed designers to choose foundation solutions tailored to each section of road, improving infrastructure durability and reducing long-term maintenance costs.

A13 Motorway – Large-Scale Geotechnical Drilling and Investigation
In the “Design and Execution – Sibiu–Făgăraș Motorway, Sections 1, 2, 3, and 4” project, carried out in partnership with MAKYOL ISTANBUL – Bucharest Branch, Dromcons was tasked with conducting complex geotechnical boreholes and providing essential technical support for the construction of a strategic motorway planned by CNAIR.

Technical details:

• Geotechnical boreholes up to 80 meters deep in areas with varied geological conditions
• Collection of disturbed and undisturbed samples for detailed physical-mechanical analysis
• Testing via heavy dynamic penetration (DPH) and standard penetration tests (SPT)
• Hydrological analysis by sampling and testing underground water
• Mapping and visual documentation of each drilling point

Our investigations provided critical information for selecting the optimal route, foundation type, and construction materials, significantly reducing the risk of delays or cost overruns.

Conclusion

If we were to list the advantages of properly executed boreholes, they would include:
