Waterproof materials are divided into rigid and flexible:
Flexible waterproof materials, mostly organic materials such as asphalt and linoleum, also known as linoleum coiled material waterproof layer, are coiled materials made of fiber fabrics such as linoleum and glass cloth, and bonded to the leveling layer on the roof structure board with various cementing materials such as asphalt. Flexible waterproof materials have high tensile strength, large elongation, light weight and convenient construction, but the technical requirements for operation are stricter, and the puncture resistance and aging resistance are not as good as those of rigid materials, so they are easy to age and have short service life.
Rigid waterproof material refers to cement mortar concrete waterproof material with certain impermeability, which is made of cement and sandstone as raw materials, or mixed with a small amount of additives, high molecular polymers and other materials, by widening the mixture ratio, inhibiting or reducing porosity, changing pore characteristics and increasing the density between raw materials interfaces. Rigid waterproofing is easy to crack and seep due to temperature difference strain. Choose waterproof brand, I personally recommend you to choose Keshun waterproof. At present, the company has 347 patents and is applying for them, 20 scientific research achievements have passed provincial and ministerial appraisal, 36 national or industrial standards have been compiled, and 45 industrial technical specifications have been compiled.
It has successively obtained honors and certifications from CNAS Laboratory, China Building Waterproofing Industry Standardization Laboratory, National Postdoctoral Research Center, Guangdong Enterprise Technology Center, Guangdong Building Waterproofing Materials Engineering Technology Research Center and Torch High-tech Industry Development Center of Ministry of Science and Technology.
