Characteristics and Application of Building Engineering-Building Waterproof Material I. Waterproof Rolls SBS coil is suitable for roofing and underground waterproofing of industrial and civil buildings, especially for building waterproofing in low temperature environment.APP coil is suitable for roofing and underground waterproofing of industrial and civil buildings, as well as waterproofing of roads and bridges, especially for buildings with higher temperature. Main properties of waterproof membrane: Waterproofing: Water permeability and anti- permeability are often used as indicators. Mechanical properties: Tensile force, tensile strength and elongation at break are commonly used. Temperature stability: commonly used heat resistance, heat resistance, brittle temperature and other indicators. Atmospheric stability: commonly used indicators of aging resistance, performance retention rate after aging, etc. Flexibility: Commonly used flexibility, low temperature flexibility, flexibility and other indicators. II. Waterproof Coatings Waterproof coatings are especially suitable for waterproofing of various complex and irregular parts, and can form a seamless complete waterproof film. III. Building Sealing Materials Building sealing materials can be divided into two types: fixed and unshaped sealing materials.Stereotyped sealing material is a kind of sealing material with certain shape and size, including all kinds of water stop tape, water stop strip, sealing strip, etc. Unstereotyped sealing material refers to the viscous sealing material such as sealant, sealant, sealant and so on.
