Macmat-R was first applied to the beach protection of Madangnan Waterway Regulation Engineering of the Yangtze River. The normal geomat is frequently damaged before its protection performance limit is reached, when applied in the water erosion control. According to the research of Maccaferri Group and Utah State University, when geomat is reinforced with wire mesh, the damage resistance can be significantly improved and the performance of the geomat can be fully played. Apart from this, the beach protection also depends on the stability of Macmat-R. Due to the light weight of the Macmat-R, the quality control on the bed flattening, intermediate pinning, overlay and lacing should be kept strictly. A satisfactory effect has been achieved at the very first application.
