The present invention is in the floor structure of the ecosystem park′s hydroponic facility that artificially create a building or apartment complex, etc., lower layer which is on the upper floor surface rubble of the ecosystem park water features are laid at a predetermined height is formed consisting of compaction; water features are provided over the underlayer and root barrier protected intermediate member being installed; and, the top layer of sand and gravel is laid over the intermediate layer; being configured, the protective member is configured as a three-layer sheet member the upper sheet, an intermediate sheet layer, the lower layer sheet made by a combination of upper sheet layer of an ethylene acrylic acid copolymer (EAA), consists of antioxidant, based on the total weight of 0.1 to 10.0% by weight it was added, the lower sheet layer is an ethylene methacrylic acid copolymer (EMAA) 50 ~ 70 wt% and oleic acid related to a floor structure of a green ecological park water features, characterized that is composed of 30 to 50% by weight. In another aspect, the present invention consists of asphalt adhesive and the protective member of the intermediate layer, EPDM (Ethylene Prophlene Diene Monomer) sheets, Bentonite sheets, any of the improved asphalt sheet is further characterized in that the combined configuration. |
