WATER BARRIER GREENING SHEET
PROBLEM TO BE SOLVED: To provide a water barrier greening sheet simultaneously exerting water barrier property and greening facilitation effect on a surface of an operation target.SOLUTION: There is provided a water barrier greening sheet 1: which comprises a first layer 2 made of a cotton water repellent short fiber nonwoven fabric of 100 mm or less in length, having 30 to 100 g/min weight per square meter, and having a thickness within a range of 5 to 20 mm; and a second layer 3 arranged below the first layer, made of a cotton water repellent short fiber nonwoven fabric of 100 mm or less in length, having a bulk density within a range of 5 to 15 kg/m. The first layer 2 has a smaller bulk density than the second layer 3 and larger thickness than the second layer. Buds and roots germinated from seeds are allowed to pass through the first layer 2 and the second layer 3.SELECTED DRAWING: Figure 1
【課題】施工対象面上において遮水性と緑化促進効果を同時に発揮する遮水緑化シートを提供する。【解決手段】長さが１００ｍｍ以下の綿状撥水性短繊維不織布からなり、その目付量が３０〜１００ｇ／ｍ２の範囲内であり、その厚みが５〜２０ｍｍの範囲内である第１層２と、この第１層の下に配置され、長さが１００ｍｍ以下の綿状撥水性短繊維不織布からなり、その嵩密度が５〜１５ｋｇ／ｍ３の範囲内である第２層３と、を有し、第１層２は、第２層３よりも嵩密度が小さく、かつ、前記第２層よりもその厚みが厚く、第１層２及び第２層３は、種子からの芽及び根が透過可能であることを特徴とする遮水緑化シート１による。【選択図】図１
