It is an important component and necessary material which can prevent the permeation of rain, underground water and other kinds of water. There are two types of waterproof conformations, rigidity waterproof-waterproof concrete, and soft waterproof. Soft waterproof has three types: waterproof sheet, waterproof coating and joint material. Ordinary soft water proofing material can be divided three types: (1) Asphalt base water proofing material, low level, lied out gradually; (2) Polymer modified asphalt, medium level, used widely; (3) Synthetic polymer water proofing material-high level, the direction of development. So far, leakage is serious in our country, and it is urgent to enhance the quantity of waterproofing. The keys to solve problem are to reasonable design, careful construct and in-time protection. What’s more, the tenet of waterproof uses rigidity and soft waterproof commonly and defends on different coats. Waterproof material is developed in the direction of higher properties, multifunction and energy efficient. ?0.2 Beasic Components of Water Proofing Material 10.2.1 Petroleum Asphalt 1. Introduction Petroleum asphalt is one kind of refined products according to crude oil distillation. Petroleum asphalt can be used to produce many kinds of corrosion resistance materials or in site petroleum asphalt directly. 2.
