Getting ready to build a house? Or maybe you're a developer in need of geotechnical investigations? Then read this guide to discover everything you need to know about geotechnical drilling.

In today’s article, we’ll walk you through what a drilling system involves, why geotechnical drilling is critical in construction and how you can get a custom offer from Dromcons in just 24 hours.

What is Geotechnical Drilling and Why Is It Essential in Construction?

Geotechnical drilling means exploring the ground beneath your project site to understand the physical and mechanical properties of the soil using specialized equipment.

Its Role in Foundation Design

The type of foundation depends on what the soil can support. For instance, a house built on sandy soil will need a very different foundation than one built on clay. 

Depth, Samples, Equipment Involved

Drilling depth can vary—from just a few meters for residential projects to 25+ meters in large-scale infrastructure developments. Using modern equipment, we perform deep drilling and collect intact samples for geotechnical soil testing, helping you make informed and safe design decisions.

Types of Drilling Services We Provide

Dromcons offers complete authorized drilling services to match a wide range of project needs:

  • Water Well Drilling – we extract underground water with high-precision equipment
  • Exploratory Drilling – we identify underground resources and study the site’s geological profile
  • Geotechnical Drilling – we assess the soil’s characteristics to support safe and stable construction
  • Micropiles and Geothermal Drilling – we install reinforcement systems in weak soils or support geothermal systems

Drilling for Civil Construction

Before building a house, industrial hall, or office block, geotechnical drilling (and occasionally water well drilling) is necessary to determine the load-bearing capacity of the terrain and the right type of foundation.

Drilling for Roads and Bridges

In road construction, geotechnical drilling helps evaluate soil stability under pavement. For bridges, we often perform deep drilling and heavy dynamic penetration tests to ensure the foundation holds up over time.

Drilling for Utilities and Agriculture

For networks such as water pipes, sewage systems, or irrigation setups, we use exploratory drilling and geotechnical drilling to determine suitable locations and depths, as well as soil composition.


Real Project Examples – Proven Results

1. DN14A Bridge, Blăjel – with GEIGER Transilvania SRL

Dromcons conducted medium-depth geotechnical drilling, shallow boreholes, and super heavy dynamic penetration tests to determine soil strength and ensure foundation stability. The project also included detailed topographic studies and full technical design services.

2. Arad Eastern Bypass – with SC PORR Construct SRL

We performed 75 boreholes at various depths as part of a complex geotechnical study for an 11 km road and 7 intersections. These results played a vital role in foundation decisions and construction planning.

3. Metropolitan Ring Road Oradea – Lot 2

This project involved 51 boreholes, up to 25 meters deep, for an 8 km road and 3 intersections. Our team delivered topographical studies, soil and foundation investigations, and lab analyses—helping secure approvals and ensure a rock-solid construction base.

How Long Does a Drilling Project Take and How Much Does It Cost?

Average Execution Time

Depending on the soil type and complexity, a drilling project can take anywhere from 1 to 3 days. For larger developments, drilling is done in phases—but our teams are efficient and equipped to stay on schedule.

Factors That Influence Cost

The price of a drilling system depends on:

  • Type and number of boreholes
  • Required depth
  • Soil conditions (e.g. hard rock vs soft soil)
  • Laboratory testing and interpretation

That said, Dromcons guarantees fair pricing, in line with industry standards and backed by experienced personnel and high-end technology.

Warranty and Documentation

Every project includes:

  • A full geotechnical report
  • Technical analysis and recommendations
  • Work warranties and legal documentation
