Vast areas of steep, terraced slopes containing exposed weathered lateritic soils along the Canal were in desperate need of erosion control. Failure to grow vegetation would trigger a costly environmental cleanup effort. In the early erosion control stages, a two-step process was utilized that included hydroseeding with Conwed Fibers® Hydro Mulch® 2000—a Thermally Refined® wood fiber mulch with tackifier, followed by the installation of Turf Reinforcement Mats (TRMs). This combination helped to ensure vegetative establishment, but came with a pretty high price tag. In order to offer a more cost effective solution for the Panama Canal Authority in subsequent phases, Profile® recommended Flexterra® Flexible Growth Medium™ (FGM™). The material was tested on bare slopes in September of 2008. The Flexterra FGM worked well—even in an area that averages 3300 millimeters of rain annually.
