NOUS CONTACTER POUR LES PRIX
Les couvertures anti-érosion Terrafibre sont des tapis haute performance conçus pour stabiliser le sol, prévenir le ruissellement des sédiments et favoriser la croissance de la végétation. Fabriqués à partir de fibres de chanvre d'Alberta cultivées de manière durable avec un support en cellulose naturelle recyclée ou en jute, ces tapis sont 100 % biodégradables et se décomposent naturellement sans laisser de résidus nocifs, ce qui les rend idéaux pour les projets sensibles à l'environnement et les applications respectueuses de la faune.
Conçues pour la stabilisation des pentes, les zones de sol perturbées, les talus routiers, les berges de cours d'eau, la remise en état des mines et les applications agricoles, les couvertures anti-érosion Terrafibre Hemp offrent une couverture exceptionnelle du sol tout en permettant à l'eau et aux nutriments de passer à travers. La structure en fibres naturelles aide à retenir l'humidité, à réduire la température de surface et à créer un microclimat qui favorise la germination des graines, le développement des racines et l'établissement à long terme de la végétation.
Les couvertures anti-érosion sont utilisées pour les applications suivantes :
- Protection des pentes
- Revêtements de canaux et de fossés
- Remblais et déversoirs de réservoirs
- Entrées et exutoires de ponceaux
- Digues
- Levées
- Rives
Applications :
- Stabilisation du sol et contrôle de l'érosion
- Réhabilitation des sites et revégétalisation
- Protection des pentes des couloirs routiers et utilitaires
- Rives, zones humides et littoraux
- Périmètres de champs agricoles et agriculture régénérative
- Infrastructure verte urbaine et projets de restauration
Le support en scrim est composé à 100 % de matériaux recyclés, dont un minimum de 40 % est du contenu post-consommation. Le renfort en corde est fait de rayonne 100 % biodégradable avec trois (3) ouvertures par pouce linéaire.
- Longévité fonctionnelle de plus de 24 mois
- Évalué sur des pentes jusqu'à 1H:1V
- Disponible en 300 g/m² ou 500 g/m²
- Sans danger pour la faune
- Alternative durable à la paille, à la noix de coco, au tremble, au jute et au polypropylène (plastique)
- 100 % biodégradable et compostable
- Facile à installer
- Rétention d'eau – Les fibres de chanvre retiennent 1050 % de leur poids en eau
Hemp erosion control
Engineered, high-performance natural erosion control
Engineered hemp fibre blankets deliver predictable longevity and complete biodegradability, with net-free options for wildlife-safe and environmentally sensitive sites. The fibre structure holds moisture, moderates surface temperature and creates a microclimate that supports germination, root development and long-term vegetation establishment.

Why hemp fibre performs
Fibre strength and durability
Hemp's natural fibre structure delivers tensile strength that outperforms straw and rivals synthetic options.
Predictable biodegradation
A 24 to 36 month degradation window aligns with vegetation establishment, avoiding both premature failure and persistent waste.
Net-free and wildlife-safe options
A non-trapping design is available, removing entanglement risk, avoiding microplastic contamination and making mowing and maintenance safer.
High lignin content
The natural lignin in hemp fibre resists UV degradation and helps hold structural integrity through changing weather.
Where these blankets are used
- Slope protection and steep slope stabilisation
- Channels, ditch linings and spillways
- Reservoir embankments, dikes and levees
- Culvert inlets and outfalls
- Riverbanks, shorelines and riparian restoration
- Wetlands and ecological buffers
- Highway and utility corridor slopes
- Mine and site reclamation, re-vegetation
- Trail and pathway stabilisation
- Agricultural field perimeters and regenerative farming
- Urban green infrastructure and restoration projects
Proven in the field
Trusted on sensitive sites across Canada
Used by Parks Canada for trails, slopes and riparian restoration in some of the country's most sensitive environments.
Frequently asked questions
What is a non-woven mat?
A non-woven mat is made by mechanically entangling fibres into a consistent sheet rather than weaving or knitting them. We needle-punch industrial hemp into a uniform mat, which lets us tune the structure to the application instead of working around a yarn and weave.
How do hemp blankets compare with straw, coconut or synthetic mats?
Hemp fibre offers tensile strength that outperforms straw and rivals synthetic options, with a degradation window that can be matched to vegetation establishment. Unlike polypropylene, nothing persists on site after the blanket breaks down.
What weights and sizes are available?
Standard blankets are produced at 300 gsm and 500 gsm. We manufacture in-house in Drayton Valley and cut to spec, so tell us your roll width, length and project requirements and we'll confirm what we can supply.
Is a net-free option available?
Yes. A non-trapping design is available for wildlife-sensitive and environmentally sensitive sites, removing entanglement risk during establishment and maintenance.
How long will the blanket last on site?
Functional longevity is 24 months or more, with full degradation typically in a 24 to 36 month window. That's designed to carry a site through vegetation establishment and then break down rather than persist.
Do you have a specification sheet?
Yes. The full specification sheet is linked above and covers material composition, backing, reinforcement and performance data for submittals.
How does pricing work?
Pricing varies by weight, roll dimensions, volume and any customisation. Send us your project details through the form and our team will come back with a quote.
Is there a minimum order?
Minimums vary by product and specification. For large-scale erosion control projects we work with you to set quantities that suit the application and budget, and trial quantities can often be arranged.
