Subdrainage optimization: use of technology in infrastructure projects

In infrastructure projects, the choice of underdrain systems is essential to ensure performance and durability. Traditional solutions can be costly and inefficient, but alternatives such as geotextile underdrainage systems or geodren and perforated pipeThe use of filter pipe or perforated pipe confined in sand or filter gravel offers significant benefits in terms of capacity, economy and ease of installation over traditional systems of subdrains in granular filter material and pipe confined with geotextile.

An optimized underdrainage system not only improves evacuation capacity, but also reduces the time during which the soil remains with excess moisture, which has an impact on the performance of the structures.

Advantages of using geotextiles for filters

The use of geotextiles for filter surrounding the perforated pipes, helps filter fine particles from the soil. These materials, when properly selected, ensure optimum permeability and strength, factors that contribute to the sustainability of the subdrainage system. The strength of the geotextile and its ability to retain particles prevents clogging of the pipe, a common problem that can lead to a misperception of the effectiveness of these systems. In long-term projects, this advantage translates into less maintenance and a longer service life.

Technical and constructive benefits

Modern subdrainage systems allow for faster installation and considerable savings in time and labor, benefiting from a smaller excavation volume, which is an advantage in infrastructure projects where the ground may be difficult or costly to excavate. In addition, the reduction in trench section minimizes material usage and construction time, which contributes to reducing environmental impact and associated costs.

Another relevant aspect is the ease of transportation. While some traditional materials require complex and costly transportation logistics, geotextile rolls and perforated drainage pipes are easy to mobilize, even in areas that are difficult to access.

Final Considerations

The use of optimized underdrain systems constitutes an advantageous option both economically and in hydraulic performance. By implementing these solutions, infrastructure projects can be significantly improved in terms of durability, economy and sustainability. As with any technology, the key to success lies in proper design and the choice of materials that meet the specific requirements of the project. These systems allow for a reduction of up to 30% in material volume and an economic savings of 20%, resulting in more sustainable and cost-effective projects.

In conclusion, optimized underdrainage with nonwoven pipe and geotextiles represents an ideal solution for projects seeking sustainability, efficiency and economy.
