Our services
drilling

Marmott offers complete drilling services for any type of terrain and project.

Drilling
vertical

Ideal for tight land areas, this method involves drilling deep wells (up to 700 feet) to maximize thermal efficiency. Sonic technology: Recognized as the most efficient drilling method, this technology reduces vibration, noise and environmental impact, particularly in sensitive areas. Marmott thus offers a less intrusive service with compact equipment, adapted to tight spaces, while minimizing drilling water management and guaranteeing a low level of noise pollution and preservation of the surrounding land.

Drilling
horizontal

Suitable for spacious sites, this method uses shallow trenches to install underground loops.

Advantages of sonic drilling

Reduced environmental impact.

Compact, discreet and respectful of the terrain.

Adaptability to various soil types and terrain configurations.

Sizing and design

Each project is unique. Our experts size and design a custom geothermal system, taking into account energy needs, site characteristics and local regulations.

Key points :

  • Design adapted to your needs and the constraints of the site: sustainable and efficient energy solution.

  • Compliance with environmental standards
    and regulatory.

Feasibility study

Before any installation, our engineers carry out geothermal feasibility studies to ensure that your project meets technical, regulatory, economic and environmental criteria.

Included items:

  • Geological analysis of the site.

  • Estimation of the building's energy needs.

  • Evaluation of the geothermal system most suited to the site.

  • Estimation of installation and operating costs.

  • Environmental impact assessment.

  • Economic analysis and profitability of the project.

Exploratory drilling (test well)

Exploratory drilling is a key step in ensuring the success of a geothermal project. Before installing a system, our experts drill test wells to accurately assess soil characteristics and the availability of hydraulic resources. This approach makes it possible to anticipate geological constraints and optimize the energy efficiency of the geothermal system.

Included items:

  • Real-world analysis of soil thermal conductivity and hydrogeological properties.

  • Validation of the sizing of the geothermal system before final installation.

  • Cost optimization.

Frequently
asked
questions

What is the average depth of a geothermal borehole?

The depth of a geothermal borehole depends on several factors, including the nature of the soil and the energy needs of the building. A single 700-foot well is generally more efficient than installing several shallower wells, because in some areas there is about 15 feet of overburden with low thermal capacity. This means that drilling multiple wells requires more work and increases costs.

What are the advantages of geothermal energy compared to other energies?

Geothermal energy has several advantages, including:
• Optimization of energy costs: A significant reduction in heating and air conditioning costs.
• Sustainability and environmental friendliness: Renewable energy source with low CO emissions2 reduced.
• Safety and reliability: Systems requiring little maintenance and offering stable operation over the long term.
• Access to grants and tax incentives: Several programs allow you to finance the installation.

What are the timeframes for carrying out geothermal drilling?

Drilling a geothermal well can take about 4 days, depending on the site challenges. Installing the heat pump takes about 3 days. If a pool heating system is included, the project can extend to a week.
