Waterproofing with bitumen has been a trusted method for decades, and Weifang Luyang Waterproof Materials Co., Ltd. specializes in providing high - quality bitumen - based waterproofing solutions. Bitumen, with its natural waterproofing properties, forms the basis of our reliable and effective waterproofing systems. Our bitumen - based waterproofing materials include SBS modified bitumen membranes, which are widely used in various construction projects. SBS modified bitumen membranes combine the durability of bitumen with the enhanced flexibility of SBS polymers. The SBS modification improves the bitumen's temperature resistance, allowing it to remain flexible in cold climates and resistant to softening in hot conditions. This makes it suitable for a wide range of geographical locations and building types. For roof waterproofing, our bitumen membranes can be installed using different methods, such as torch - on, self - adhesive, or cold - applied systems. Torch - on membranes provide a strong and durable bond when heated, creating a seamless waterproof layer. Self - adhesive membranes offer convenience and ease of installation, reducing the need for additional equipment. In underground waterproofing, bitumen - based waterproofing can effectively resist hydrostatic pressure. Our bitumen membranes adhere well to concrete and other underground substrates, forming a reliable barrier against groundwater and moisture. They are also resistant to chemicals and salts commonly found in the soil, ensuring long - term durability. With our expertise in waterproofing with bitumen, we provide customized solutions for each project, ensuring effective and long - lasting waterproofing protection.
