Get Price ListPortugal’s diverse topography—ranging from the high-rainfall northern mountain ranges down to the semi-arid terrains of the Alentejo and the tourist-dense coasts of the Algarve—presents highly distinct challenges for modern civil engineering, water resource management, and environmental containment systems.
With national transport programs such as the Porto-Lisbon high-speed rail line project and the expansion of the Lisbon subway network, the demand for highly reliable subgrade reinforcement materials has reached historic highs. Geonets are critical here to manage subsurface water, prevent structural settlement, and resist freeze-thaw degradation cycles.
Simultaneously, Portugal faces structural water challenges. Large-scale agricultural investments like the Alqueva reservoir system demand heavy anti-seepage and drainage membranes to preserve water assets. In environmental protection, regional landfills require multi-layered lining systems combining geonets, geomembranes, and geosynthetic clay liners (GCL) to secure local aquifers against leachate contamination.
Portugal's long Atlantic coastline demands rapid drainage systems behind retaining structures to reduce hydrostatic pressure and prevent premature structure failure.
Strict regulatory oversight by the Portuguese Environment Agency (APA) requires all municipal landfill and industrial storage systems to use verified geotextiles.

Using computerized screw extruders, we ensure consistent melt temperature and pressure, generating uniform bi-planar and tri-planar geonets with highly reliable rib structures.
Continuous digital monitoring of grid opening dimensions and polymer crystallization guarantees superior long-term hydraulic transmissivity under severe environmental stress.
From raw virgin polymer resin feedstocks down to finished wrapped rolls, every batch undergoes mechanical tensile strength and flow index testing before port delivery.
Our modern factory floor implements systematic controls across six critical operational stages:
Polyester chips, premium virgin high-density polyethylene (HDPE), and polypropylene filament are strictly checked for moisture content and density stability.
Resin is extruded in a controlled inert atmosphere to preserve long-chain polymer integrity, ensuring high creep resistance for underground installations.
Molten polymer is extruded through custom dies, establishing the intersecting rib configuration that provides three-dimensional drainage paths.
Controlled cooling rates and mechanical tension draw patterns maximize the raw load capacity and optimize environmental stress cracking resistance (ESCR).
Finished rolls are measured for physical thickness and flow capacity, before being wrapped in UV-protective film and cataloged with internal QC barcode tracking.
Use these baseline engineering values to match our geosynthetics to local LNEC and EU standards.

In landfills, modern regulatory design dictates the use of a composite liner system. A high-density polyethylene (HDPE) geonet functions as the primary drainage layer directly above the geomembrane liner. The geonet must possess high compressive stiffness to withstand the massive loads of municipal waste.
The tri-planar design maintains open hydraulic pathways even under normal pressures exceeding 500 kPa. By draining leachate quickly, it prevents hazardous buildup and reduces hydrostatic pressure, minimizing the risk of seepage into groundwater reserves.
Subsurface water is a primary cause of road pavement cracking and base failures. Installing a composite geonet beneath the road subbase intercepts rising groundwater and lateral infiltration.
This drainage layer acts as a capillary break, protecting the structure from water damage. Our geonets feature optimized rib configurations that resist base aggregate intrusion, providing long-term stabilization for heavily trafficked highway systems.
