The mattress is lined with a filter fabric and is then filled.Our GeoMac units are mattress shaped cages, engineered from double twisted hexagonal woven steel wire mesh. The mattress is lined with a filter fabric is then filled on site with a stone-soil mix to provide a contained panel of topsoil, confined within a steel wire mesh cage. The lid of the mattress is also lined with an erosion control matting to prevent the contents spilling out of the unit.
GeoMac® is designed to revegetate and their principal use is on wet slopes to provide a green finish to a channel revetment. It can also be used on dry slopes to ensure a robust erosion resistant finish.
For erosion control, GeoMacs® combine engineering protection to water flow with environmental benefits.
