屋面防水是建筑工程中存在的质量通病,也是多年来一直未能很好解决的难题。目前,较多采用的是刚性及柔性防水两种做法。刚性防水由于温差应变,易开裂渗水;柔性防水,多为沥青,油毡等有机材料,易老化,寿命短。近年来,虽然各种新型防水材料相继问世,但由于价格较高,缺乏施工经验,且耐久性还有待于进一步检验等原因。因此,目前还是采用较为廉价的材料为主。 Roofing waterproofing is a common problem in construction quality, but also has not been a good solution for many years. At present, more rigid and flexible waterproof two methods are used. Rigid waterproofing due to temperature and strain, easy to crack water seepage; Flexible waterproof, mostly asphalt, linoleum and other organic materials, easy to aging, short life expectancy. In recent years, although a variety of new waterproof materials come out one after another, but due to higher prices, lack of construction experience, and durability needs to be further tested and other reasons. Therefore, the current use of cheaper materials mainly.
