The materials used in the modules are high-quality FRP, similar to those used in marine structures and industrial storage tanks. If the instructions in the technical installation manual are followed closely and all additional materials (sealants, fasteners, waterproofing, geo-textiles) are used as specified, you can expect a long lifespan with minimal maintenance. Over time, necessary maintenance or repairs will be minor and straightforward. The soil, grass, and plant coverage help protect the structure from UV rays and harsh weather conditions.
