復合土工膜應有較小的滲透系數、較好的滲透穩定性和一定的塑性。粘性土一般都可用作防滲料。防滲料鹽類含量不得超過規范的允許值。上壩土料的含水量（水和干土的重量比）應控制在最優含水量附近，使施加相同的壓實功能可獲得最大干容重（單位體積干土重）。如料場的天然含水量過干或過濕應進行處理。世界上廣泛采用礫石土作為高土壩的防滲料。這種土同時含有粒徑大于5mm的粗粒和小于5mm的細粒。</span><br /> <span style="font-size:16px;line-height:2.5;font-family:Microsoft YaHei;">　</span><span style="font-size:16px;line-height:2.5;font-family:Microsoft YaHei;"> 復合土工膜以土工膜膜的不透水性隔斷土壩漏水通道，以其較大的抗拉強度和延伸率承受水壓和適應壩體變形；而無紡布亦是一種高分子短纖維化學材料，通過針刺或熱粘成型，具有較高的抗拉強度和延伸性，它與塑料薄膜結合后，不僅增大了塑料薄膜的抗拉強度和抗穿刺能力，而且由于無紡布表面粗糙，增大了接觸面的磨擦系數，有利于復合土工膜及保護層的穩定。同時，它們對細菌和化學作用有較好的耐侵蝕性，不怕酸、堿、鹽類的侵蝕。復合土工膜防滲技術在水利水電工程、鐵路、公路工程、隧道工程、垃圾處理廠、建筑工程等現代建設工程中廣泛運用。</span><br
