Reinforcing vegetation on steep slopes exposed to intense Caribbean rain where coir biomats biodegrade prematurely, anchoring grass and plant roots with a permanent system that adds three-dimensional structure to the substrate, and lining channels with water flow where erosion control must last for decades, requires a three-dimensional polypropylene geomat with high-strength filaments and an open 3D matrix. This polypropylene (PP) geomat—also known as a turf reinforcement mat, TRM, 3D geomat, or volumetric revegetation mesh—is manufactured by MOLTEXO from stabilized PP filaments intertwined in a three-dimensional matrix, with a weight of 100 g/m² in green, in rolls 5.2 m wide and 100 m long, designed for permanent slopes, flowing channels, riverbanks, reclaimed landfills, and landscaping projects with a long service life.
Key Benefits
- Permanent three-dimensional structure for root anchorage: the open 3D matrix is filled with topsoil and accommodates grass and plant roots, which interweave with the PP filaments, creating a double-reinforcement system (vegetation + synthetic) that significantly increases resistance to water erosion.
- Long-lasting UV-stabilized PP: unlike coir biomats that biodegrade in 2-5 years, the synthetic geomat maintains its structural function for decades, which is essential for permanent applications where vegetation alone does not provide sufficient resistance under extreme conditions.
- High permeability for natural infiltration: the open matrix allows rainwater to pass through without generating significant lateral runoff, maintaining natural water flow into the subsoil and reducing the risk of surface saturation.
- Immediate protection from installation: before vegetation is established, the PP filaments reduce direct rain impact and runoff velocity, preventing substrate loss during the critical period of germination and initial growth.
- Flexible and adaptable to irregular terrain: the material conforms to uneven surfaces, curves, and complex slope shapes, ensuring continuous contact with the surface without gaps where water could flow under the mat and wash away the substrate.
Typical Applications and Uses
- Permanent stabilization of slopes and hillsides in road, urban development, and residential projects.
- Lining drainage channels, ditches, and trenches with continuous or intense intermittent water flow.
- Protection of riverbanks, lagoons, and coastal areas from water and wind erosion.
- Covering reclaimed landfills, environmental closure zones, and landscaping projects with permanent native vegetation.
Quality and Durability
An economical geomat fails in two areas: the PP filaments lack adequate UV additive (leading to embrittlement and disintegration after a few years in direct sunlight) and the three-dimensional matrix is thin or not calibrated (which does not properly house substrate or roots, losing the combined reinforcement effect). MOLTEXO works with UV-stabilized PP in a calibrated 3D matrix, which distinguishes a permanent construction geomat with a lifespan of decades from a generic geomat that fails before vegetation establishes itself.
