COTEC — Grupo Cobian
Green slope with anchored K-MAT RF METAL geomat installed by COTEC over a steep grade

Line 03

Erosion control and soil reinforcement

Geosynthetic systems built for Caribbean reality: steep grades, tropical rainfall, heterogeneous soils.

COTEC + TeMa Geo Solutions

COTEC supplies and installs erosion control, soil reinforcement, and subsurface drainage systems from the TeMa Geo Solutions family. We don't sell rolls: we deliver the full system — technical diagnosis, spec per applicable standard, installation by trained crews, and on-site supervision through handover.

Application 01

Slope stabilization

Highway cuts, natural slopes, and engineered embankments that need a permanent protective layer against erosion without giving up drainage.

  • K-MAT installed on a slope with vegetation growing through the geomat

    K-MAT®

    Three-dimensional polypropylene monofilament geomat. Allows vegetation to grow through, delivering permanent stabilization.

    Thickness10 / 16 / 22 mm

  • K-MAT RF METAL installed on a rocky slope with hexagonal Galfan mesh visible

    K-MAT® RF METAL

    Geomat bonded to double-twist hexagonal mesh in Galfan alloy. For steep or rocky slopes where vegetation alone isn't enough.

    Mesh6×8 / 8×10 cm
