土工布特点1、强力高，由于使用塑料纤维，在干湿状态下都能保持充分的强力和伸长。
2、耐腐蚀，在不同的酸碱度的泥土及水中能长久地耐腐蚀。
3、透水性好 在纤维间有空隙，故有良好的渗水性能。
4、抗微生物性好 对微生物、虫蛀均不受损害。
5、施工方便，由于材质轻、柔，故运送、铺设、施工方便。
6、规格齐全: 幅宽可达9米。是目前国内最宽产品，单位面积质量:100-1000

防渗土工布以塑料薄膜作为防渗基材，与无纺布复合而成的土工防渗材料，它的防渗性能主要取决于塑料薄膜的防渗性能。国内外防渗应用的塑料薄膜，主要有聚氯乙烯(pvc)和聚乙烯(pe)，它们是一种高分子化学柔性材料，比重较小，延伸性较强，适应变形能力高，耐腐蚀，耐低温，抗冻性能好。其主要机理是以塑料薄膜的不透水性隔断土坝漏水通道，以其较大的抗拉强度和延伸率承受水压和适应坝体变形;而无纺布亦是一种高分子短纤维化学材料，通过针刺或热粘成形，具有较高的抗拉强度和延伸性，它与塑料薄膜结合后，不仅增大了塑料薄膜的抗拉强度和抗穿刺能力，而且由于无纺布表面粗糙，增大了接触面的摩擦系数，有利于复合土工膜及保护层的稳定。同时，
