When planting the lotus root, both geomembrane and composite geomembrane can be used to prevent seepage and resist root. The site on which the geomembrane or composite geo-membrane is laid should be properly treated. Before laying those materials, the site should be levelled and pressed firmly without sharp stones and branches on it. For example, if mountainous ground is uneven, loess should be laid to level it. When the geomembrane is laid, it is strictly prohibited to move machinery on it. Workers that lay the geomembrane should wear flat shoes to walk on it. After the geomembrane is laid, soil of certain thickness needs to be backfilled on the geomembrane to protect it.especially in the area above the water around the lotus pool to prevent the sun exposure and the aging of geomembrane.
