TerraGuarda delivers technical revegetation, slope stabilisation and preventive soil protection systems — formulated for the specific substrates, climates and challenges of the Portuguese territory. International experience across 10 countries.
Every project receives a site-specific formulation — substrate, slope, climate and erosion risk define the system, not a standard catalogue. The same methodology developed across infrastructure, post-fire and arid-zone projects in 10 countries.
Road embankments, railway corridors, dams. Formulations by substrate class and inclination.
Immediate stabilisation before the first autumn rains. By helicopter or ground equipment.
Natural polysaccharides. Formulated to EU approval criteria for application of substances in open landscape. Dust fixation, unpaved tracks, coastal dune stabilisation.
Thermal barrier by spray application. Zero phosphate. Buffer zones along infrastructure corridors.
UAV and helicopter formulations. Remote zones, steep slopes without ground access.
RUSLE erosion modelling, vegetation simulation, technical specifications for public tenders.
Portugal is not a homogeneous substrate. Granite in the north, schist in the centre and Alentejo interior, coastal sands in the south — each region requires an adapted formulation. We work with actual soil characteristics.
Skeletal soils on schist and granite with high stoniness and low water retention. After wildfire, the first autumn rainfall events transport topsoil that took decades to form. The dry summer demands matrices with high water retention to ensure germination.
Coastal sands with rapid drainage, low nutrient content and minimal organic matter. Dune stabilisation requires systems that bind particles without harming native halophytic vegetation. Limestone slopes in the eastern Algarve present high pH and concentrated water erosion.
Granite and metamorphic rock create skeletal soils on steep slopes. Intense winter rainfall on soils destabilised by construction or fire generates sheet and rill erosion. Low winter temperatures require formulations with an extended germination window.
The region most affected by the major historical wildfires of 2017 and 2025. Schistous soils with high erodibility after vegetation loss. Steep slopes in sensitive river catchments require rapid intervention — ideally aerial application within the first weeks after fire.
Infrastructure, post-fire, mining and arid-zone projects across multiple countries — including Mediterranean, semi-arid and alpine climates. Portugal is the natural expansion for the European market with the highest erosion pressure and wildfire risk.
