The use of perforated foundation systems DTH to introduce casing tubes in the ground, offers many advantages compared to the conventional techniques of piloting the construction of foundations.

• It allows the realization of drilling for foundation with DTH in urban areas.
• Increase productivity.
• Lower well construction costs.
• Improves operational efficiency and safety.
• Minimizes the environmental impact.
• Reduce incidents of well collapse.
• Provides superior well cleaning and annular geometry.
• Creates a more concentric well and improves the potential quality of the cement.
