The Flex MSE Vegetated Wall System uses the same globally accepted principles of Mechanically Stabilized Earth that builders rely on for making massive retaining walls. Geobag walls with less robust technology and components than Flex MSE have been built as high as 75ft tall, with great success. Our Second Generation interlocking Plate is a 100% recycled, recyclable component which adds increased geogrid compatibility and friction strength over its precursors. Flex MSE is a unique soft building material that exhibits hard material qualities. It weathers events that would ruin other systems, and only gets stronger and greener as time goes on.
