Waterproof roll materials play a crucial role in the construction industry, safeguarding buildings from water damage. These materials are designed to be flexible and can be rolled out, making them convenient for application on various surfaces.
There are mainly three types of waterproof roll materials. The first is asphalt waterproof roll materials, which were widely used in the past. However, due to some limitations, they are being gradually replaced. The second type is high - polymer modified asphalt waterproof roll materials. SBS modified asphalt waterproof rolls, for example, are highly popular. They can withstand a wide temperature range, from - 25℃ to + 100℃. They also have excellent elasticity, fatigue resistance, with an elongation rate of up to 1500% and strong puncture and tear resistance. The third type is synthetic polymer waterproof roll materials, such as PVC waterproof rolls. PVC rolls are made with polyester fiber fabric as reinforcement, offering high strength and good waterproof performance. They are suitable for a variety of waterproof projects, including industrial and residential building roofs, basements, and tunnels.
Waterproof roll materials are characterized by good water resistance, high tensile strength, and excellent flexibility. They can adapt to the deformation of the base layer without cracking. In construction, they are applied through different methods, such as hot - melt method, cold - adhesion method, etc. Their wide application has effectively improved the waterproof performance of buildings, ensuring the durability and safety of structures.
