French Drain and Geodrain as sub-drainage systems – Comparative analysis
An adequate subdrainage system is essential for the optimal performance of any structure. There are alternatives such as the geodrain that, unlike the French drain, offer a solution with a remarkable percentage of savings and efficiency.
Civil Engineer Patrick Fuentes will talk about this in the following video, emphasizing the characteristics, performance, installation and costs of each of them. Remember that you can also check out the transcript of this video below.

Comparative analysis between the French drain and the geodrain as subdrainage systems
A subdrainage system is a structure designed to capture and evacuate subsurface water, in order to control levels and keep a soil mass or projected structure dry. There are two alternatives for its formation.
On the one hand, the french drain It is a sub-drainage system made up of an excavation, the placement of a geotextile as a filter medium, a drainage medium made up of gravel or sand and a pipe at the bottom to evacuate the captured water.
French Drain and Geodrain as sub-drainage systems
On the other hand there is the geodren, a geocomposite for underdrainage made up of a geotextile as a filter medium, a geonet as a drainage medium and a geotextile cover in the lower part, which houses the pipe that evacuates the captured water.

Performance of the French Drain and the Geodren
The French drain is sensitive to the correct selection of materials, since the geotextile is placed in contact with the ground, being susceptible to clogging. In the case of the geodrain, the geonet has a high hydraulic capacity and the geotextile is in contact with a pre-filter layer, which prevents clogging.
Material Yield
We have observed that with the use of a geodrain, savings of up to 30% can be obtained, given that the construction of a French drain requires a larger section of excavation and therefore a larger volume to form the drainage medium.
With the use of the geodrain, as it is a laminar element, a smaller excavation section and a smaller volume of material are required to form the pre-filter layer.
The aforementioned performance results in cost savings of around 20%, since in this type of solution what has an impact is the volume of excavated material and the transport of materials to the work site.
In conclusion, the geodrain is a cost-efficient and technically viable subdrainage system, however, the most appropriate solution must be selected based on an analysis of the conditions of each project, for which Geomatrix is fully available to advise you. .
