Flex MSE Unfilled Unit (Bag & Plate)

Flex MSE - A Cost-Effective, Sustainable and Permanent Engineered Solution.

The Flex MSE Vegetated Wall System is a cost-effective, sustainable, and permanent retaining wall solution designed for erosion control, slope stabilisation, and landscaping projects. Built on the proven principles of Mechanically Stabilised Earth (MSE), Flex MSE installations have been successfully constructed at heights of up to 75ft, delivering long-term stability and performance.

Each unit features a patented interlocking plate, made from 100% recycled and recyclable materials, designed to enhance geogrid compatibility and friction strength within the reinforcement system. Unlike traditional retaining wall systems such as rigid concrete blocks, Flex MSE walls adapt to settlement and drainage, resisting damage from water and soil movement. As live plants establish, Flex MSE becomes stronger and greener, forming a vegetated retaining wall system that blends naturally into the environment.
