Geodrain
Combination of non-woven geotextile for filtration and separation and a geonet that presents in a single product a subdrainage system that captures and conducts groundwater.
permadrain
The Permadrain geodrain is a geocomposite that presents a complete drainage system in a single product, with a drainage medium of the HDPE geonet type and a non-woven geotextile filter medium.. The geonet offers high resistance to compression, keeping its thickness constant under high load requirements. The geotextile is made up of fibers that allow the efficient passage of water, preserving its geometry and pore opening size under the most demanding stress and/or confinement conditions.
It is available in two references, Planar Permadrain composed of the drainage medium and the filter geotextile on both sides, designed to form horizontal or vertical sub-drainage systems in containment structures and specific works, and the Tubular Permadrain, which includes a lower sleeve to house the DRAINPIPE perforated pipe for the evacuation of captured water, designed mainly for vertical drainage in linear works.

___________ Advantages _____________
Prevents water accumulation and relieves pore pressure.
Its filter media avoids the passage of fine particles into the draining media, guaranteeing its performance and useful life.
Allows the construction of drainage and subdrainage systems by reducing the excavation trench section.
Reduces installation times and lowers construction costs.
It is lightweight and easy to carry.
It is more efficient and economical compared with other traditional subdrainage solutions
It does not generate environmental impact and is highly resistant to chemical and biological attacks.
It offers high resistance to compression, withstanding high pressures or earth pressures while maintaining its efficiency.
