TECCO GREEN is high-tensile TECCO G65/3 mesh combined at the factory with a polypropylene erosion control mat: anchored stabilization and surface erosion protection in one step; seed and vegetation take hold through the mat.
What it does
An anchored mesh holds the slope, but fine material can wash out through the mesh openings and cut channels; on a moving, eroding surface vegetation cannot take hold. TECCO GREEN brings these two jobs together in one product: the high-tensile TECCO G65/3 mesh transfers the load to the nails, and the three-dimensional polypropylene mat integrated into the mesh protects the surface from erosion and becomes an anchoring layer for the sprayed seed-mulch mix. It is the manufacturer's answer to the problem that natural mats such as jute and coir do not lie flat on the surface and do not let hydroseeding through.

The mesh side is TECCO G65/3: 3 mm wire, ≥ 1,770 N/mm², 83 × 143 mm mesh, 150 kN/m. System plates, nail pattern and dimensioning are as on the TECCO SYSTEM3 page.
Where
On soil and weathered rock slopes, in dam and road cuts; where the surface is to be closed with a permanent vegetation cover and anchored stabilization is needed. On slopes that need only erosion protection and have no stability problem, a mat without mesh and hydroseeding are enough; the decision is made by the surface condition measured during the survey.
