Waterproofing membranes are a type of rollable sheet waterproofing material that is widely used in construction projects.They are mainly used to prevent water penetration and protect structures from water damage. According to their main constituent materials, waterproofing membranes can be divided into the following categories:
Polymer waterproofing membranes: Made from synthetic rubber or synthetic resin as the main raw material, with appropriate amounts of chemical additives and fillers added, and processed through different processes. Its characteristics include high strength, high elasticity, aging resistance, and simple construction.
Asphalt waterproofing membranes: After the base is dipped in asphalt, powdered or flaky isolation materials are spread on the surface. Asphalt waterproofing membranes have good water resistance, temperature stability, and certain mechanical strength, elongation, and fracture resistance.
Polymer cement waterproofing coatings (JS waterproofing coatings): Made from a mixture of polymers and cement, they have good bonding properties, low-temperature flexibility, self-healing ability, and environmental protection requirements.
Self-adhesive waterproofing membrane: With synthetic rubber such as SBS, tackifier and high-quality road petroleum asphalt as the base material, it has low-temperature flexibility, self-healing and good bonding properties.
Polyvinyl chloride (PVC) waterproofing membrane: With polyvinyl chloride resin as the main raw material, adding a variety of chemical additives, it is processed by mixing, extrusion molding and vulcanization.
Performance characteristics and application scenarios Polymer waterproofing membrane: With high strength, high elasticity and aging resistance, it is suitable for waterproofing projects under various climatic conditions.
Asphalt waterproofing membrane: With good water resistance and temperature stability, it is suitable for roofing and underground waterproofing projects.
Polymer cement waterproofing coating: With strong bonding performance and self-healing ability, it is suitable for occasions that require rapid construction.
Self-adhesive waterproofing membrane: With low-temperature flexibility and self-healing, it is suitable for construction in low-temperature environments.
Polyvinyl chloride (PVC) waterproofing membrane: With good chemical stability and weather resistance, it is suitable for outdoor and chemical corrosion environments.
Construction method
Polymer waterproofing membrane: No complex equipment is required, it can be laid directly, with a short construction period and is not affected by the temperature.
Asphalt waterproofing membrane: Made by dipping and spreading isolation materials, it is easy to construct.
Polymer cement waterproofing coating: Construction at room temperature, strong adaptability.
Self-adhesive waterproofing membrane: It can be laid at room temperature, simplifying the construction process.
Polyvinyl chloride (PVC) waterproofing membrane: It is processed through mixing, extrusion molding and vulcanization, and attention should be paid to temperature control during construction.
