Drilling Division

DRILLING: Distribution of tubular steel reinforcements and geothermal probes. We collaborate with European suppliers for the manufacture of the micropile as a low enthalpy geothermal exchanger. We act as product distributors and project manager for the quality control of the on-site execution of this type of foundations.

We can supply two types of reinforcement: new or first generation tubes welded in N80 steel and second generation tubes (used) welded in N80 steel with the corresponding certificate of control. The main dimensions of the tubes normally available in our central warehouse are:

The vertical geothermal probe is designed to capture the energy of the ground through a fluid based on Monopropylene Glycol. The characteristics of the vertical geothermal probes are:

– Material: High Density Polyethylene -PE 100 RC.

– Product designed and manufactured according to ISO 9001 quality standards.

– Useful life of 100 years under normal conditions of use.

In addition, we also supply the probe foot and the geothermal mortar with specific characteristics.
