地面返潮是我国南方地区的通病。地面返潮原因较多。而截断毛细管水上升这是防潮的关键所在。解决地面返潮问题有多种方法,如采用一毡二油或玛(王帝)脂,使用防水混凝土或防水砂浆等,这些方法防潮效果虽然较好,但施工较为复杂,造价高。近年来,我们在几个工程中试用了抗老化性能强、塑性好、密实度高的塑料薄膜作防潮层,施工简单,造价低廉,每m~2造价仅0.90元,比一毡二油(3.3元/m~2)、玛(王帝)脂(1.5元/m~2)便宜。塑
Ground flooding is a common problem in southern China. There are many reasons for ground flooding. The interception of capillary water rise is the key to moisture protection. There are many ways to solve the problem of ground flooding, such as the use of a felt or oil (Wang Di) grease, the use of waterproof concrete or waterproof mortar, etc. These methods are better, but the construction of the method is more complex and expensive. In recent years, we have tested plastic films with high anti-aging performance, good plasticity, and high density in several projects as a moisture barrier. The construction is simple, and the cost is low. The cost per m2 is only 0.90 yuan, which is lower than that of a felt and oil ( 3.3 yuan / m ~ 2), Ma (Wang Di) fat (1.5 yuan / m ~ 2) cheaper. Plastic
