The erosion control blankets TRM are essential in the protection of uncovered slopes exposed to rainfall or surface runoff. These terrains, especially those with low cohesion soils, usually suffer from laminar erosionThe process is characterized by the uniform loss of fine particles that compromises soil stability and hinders the establishment of vegetation. According to the FAO on soil erosionThis type of degradation is one of the main threats to the sustainability of ecosystems and soil productivity.

In this scenario, the erosion control mats TRM (Turf Reinforcement Mats) become an effective solution, providing immediate protection and, at the same time, favoring the establishment of a long-lasting vegetation cover.

TERRATRAC TRM: a permanent solution

At Geomatrix we offer the TERRATRAC TRM mantledesigned to provide immediate protection against erosion, support the growth and establishment of vegetation, and act as a permanent reinforcement of mature vegetation.

He TERRATRAC TRM is made of non-degradable, UV-resistant, synthetic polyester fibers that form a three-dimensional matrix. It is available in the following references TRM 15 and TRM 50according to its ultimate tensile strength.

Outstanding features:

  • Easy to install roll-up product.

  • Provides immediate protection even before vegetation grows.

  • High resistance to hydrodynamic forces in slopes and channels.

  • Reduces abrasion and particle shedding caused by rain.

  • Retains soil and controls runoff thanks to its porous matrix.

  • Allows seeding before or after installation.

Key factors for the establishment of vegetation

The success of a TRM mantle depends not only on the material, but also on the correct integration with the vegetation and the initial soil management:

  1. Selection of plant species

    • Prefer species with fibrous and dense roots that intertwine with the matrix of the TRM.

  2. Soil preparation

    • Scarification to improve infiltration and contact between roots and mulch.

    • Ensure basic nutrients such as nitrogen, phosphorus and potassium.

  3. Humidity and initial irrigation

    • Maintain constant humidity in the early stages.

    • Implement temporary irrigation in the absence of rainfall.

  4. Correct installation of the TRM

    • Fastening with stakes or staples to avoid voids or air pockets.

    • Complete adaptation to the terrain.

  5. Initial maintenance

    • Weed control.

    • Support fertilization in the first months.

Benefits of using TRM in slopes with laminar erosion

  • Immediate protection against fine particle entrainment.

  • Structural reinforcement that supports water flows and favors vegetation.

  • Long-term durability, with permanent protection even under changing climate conditions.
