Permadrain

geodrain

Combination of non-woven geotextile for filtration and separation and a geonet that presents in a single product a sub-drainage 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 HDPE geonet type drainage medium and a non-woven geotextile filter medium.. The geonet offers high resistance to compression, keeping its thickness constant under high load requests. The geotextile is made up of fibers that allow the efficient passage of water, conserving its geometry and pore opening size under the most demanding conditions of tension and/or confinement.

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 retaining 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  _____________

Permadrain

 

Prevents water build-up and relieves pore pressure.

Permadrain

 

Its filtering medium prevents the passage of fine particles towards the draining medium, guaranteeing its performance and useful life.

Permadrain

 

It allows the construction of drainage and sub-drainage systems, reducing the section of the excavation trench.

Permadrain

 

Reduce installation times and lower construction costs.

Permadrain

 

It is a light and easy to transport product.

Permadrain

 

It is more efficient and economical compared to other traditional subdrainage solutions.

Permadrain

 

It does not generate environmental impact and is highly resistant to chemical and biological attacks.

Permadrain

 

It offers high resistance to compression, withstanding great pressures or earth pressures while maintaining its efficiency.
