Introduction

Earthworks are one of the most basic stages in every construction project. From a small private plot to a large technical facility, proper ground preparation directly affects the stability, safety, and longevity of the project. In this article, we present everything an owner needs to know before starting.

What Are Earthworks?

Earthworks include all processes related to the preparation and grading of the ground. They concern:

  • Excavations and backfilling.

  • Leveling & plot grading.

  • Site clearing (Clearing of plots).

  • Transport of aggregates.

  • Road opening/construction.

  • Creation of sewage infrastructure.

  • Landscaping for gardens and outdoor spaces.

These are tasks that require specialized equipment, such as excavators, JCBs, loaders, diggers, and trucks.

When Are Earthworks Needed?

The most common cases where they are required are:

  • New building construction or house extension.

  • Installation of a cesspool/septic tank or sewage system.

  • Construction of fencing.

  • Outdoor space landscaping (garden, yard, parking).

  • Commercial facilities.

  • Infrastructure for agricultural plots.

It is "step 1" before any construction begins.

How Much Do Earthworks Cost?

The cost depends on:

  • The amount of soil that needs to be moved.

  • The type of soil (hard, rocky, soft).

  • Machinery access to the plot.

  • The operating time of the machinery.

  • The need for additional materials (Road base 3A, sand, gravel, etc.).

💡 Indicative Price:
Simple earthworks start approximately from 40–70€ per machine hour, while more demanding projects can reach higher amounts.

Tips Before You Start a Project

  • Ask for a detailed quote to know exactly what is included.

  • Choose a professional with their own equipment for lower costs and better quality.

  • Check access to the plot so that no extra charges arise.

  • Ensure that the necessary permits exist, if required.

Conclusion

Earthworks are decisive for every construction project. With proper study, a specialized crew, and appropriate machinery, the project becomes safe, stable, and ready for the next stages.
