    Introduce

    In modern construction and industrial applications, the selection of waterproofing materials is crucial. With the increasing requirements for environmental protection and energy saving, the selection of building materials has become particularly important. Choosing the right reinforcement material can not only improve the performance of the structure, but also extend its service life and reduce maintenance costs. As a high-performance reinforcement material, fiberglass is widely used in many fields due to its excellent mechanical properties, corrosion resistance and lightweight characteristics. This article will explore in depth why fiberglass is important for waterproofing, and introduce different types of fiberglass and their characteristics in detail, analyze their application in waterproofing materials, and finally help you choose the most suitable type of fiberglass for waterproofing.

    Why is fiberglass important for waterproofing?

    Enhance structural strength

    Fiberglass has extremely high tensile and compressive strength, and can maintain stability and durability when subjected to large external forces. This not only improves the overall structural strength of the waterproof layer, but also reduces the risk of deformation and damage caused by external pressure.

    Improve corrosion resistance

    Fiberglass has good tolerance to chemicals such as acids and alkalis, and is suitable for various corrosive environments. This not only extends the service life of the waterproof layer, but also reduces maintenance costs. It is especially important for waterproofing projects that are exposed to harsh environments for a long time.

    Improve flexibility and crack resistance

    Glass fiber has excellent flexibility and crack resistance, and can maintain stable performance under temperature changes and stress. This is very important for waterproof projects that need to adapt to complex environments, ensuring that the waterproof layer will not crack or fail due to temperature changes or stress.

    Improve construction efficiency

    Glass fiber is soft, easy to cut and shape, and can be customized according to specific sizes, which greatly simplifies the construction process. Compared with traditional materials, glass fiber is lighter, reduces the requirements for supporting structures, and reduces installation costs.

    Types of glass fiber and their characteristics

    Chopped strand mat

    • Features: Chopped strand mat is made of randomly distributed short chopped glass fibers and has good waterproof performance and corrosion resistance. However, its strength is relatively low and is not suitable for structures that withstand large external forces.
    • Application: Mainly used in the manufacture of composite materials, such as hand lay-up and compression molding. Although it is not suitable for large-area structural reinforcement, it performs well in local repair and reinforcement.

    Roofing mat

    • Features: Fiberglass roofing mat is woven from criss-cross fibers and has high tensile strength and good air permeability. However, its waterproof performance is relatively weak and cannot completely prevent moisture penetration.
    • Application: Mainly used for wall reinforcement and crack repair, enhancing the stability and durability of the structure. Although the waterproof performance is not as good as other materials, its reinforcing effect is significant.

    Polyester mat

    • Features: Polyester mat combines the high strength of glass fiber and the flexibility of polyester fiber, and has excellent mechanical properties and corrosion resistance. Suitable for occasions requiring high strength and corrosion resistance.
    • Application: Widely used in waterproof roll materials, thermal insulation, wall reinforcement and other fields, providing longitudinal reinforcement to ensure that the structure maintains stability and durability when subjected to internal and external pressure.

    Mesh cloth

    • Features: Mesh cloth is woven from criss-cross fibers, with high tensile strength and good air permeability. Suitable for occasions where structural stability and durability need to be enhanced.
    • Application: Mainly used for wall reinforcement and crack repair, enhancing the stability and durability of the structure. Although the waterproof performance is not as good as other materials, its reinforcing effect is significant.

    Application of glass fiber types in waterproof materials

    Application of chopped mat

    • Waterproofing membrane: Chopped mat can be used as the base material of waterproofing membrane to provide certain reinforcement. Although its strength is low, it performs well in local repair and reinforcement, and is suitable for small-area waterproofing projects.
    • Anti-corrosion coating: Chopped felt is often used as the bottom layer of anti-corrosion coating to provide initial reinforcement and prevent the coating from cracking or falling off.

    Application of roofing mat

    • Roof waterproofing:Fiberglass roofing mat is widely used in roof waterproofing projects, providing certain tensile strength and corrosion resistance. Although its waterproof performance is relatively weak, it can be used by multi-layer stacking to improve the overall waterproofing effect.
    • Wall reinforcement: Roofing felt can also be used for wall reinforcement to enhance the stability and durability of the structure, and is suitable for exterior wall waterproofing and crack repair.

    Application of polyester mat

    • Waterproofing membrane: Polyester felt is an ideal base material for waterproofing membrane, providing excellent tensile strength and corrosion resistance. Ensure that the waterproof layer is strong and durable, suitable for large-area waterproofing projects.
    • Thermal insulation: Polyester felt is widely used in thermal insulation projects, providing efficient thermal insulation effects, reducing heat transfer, and is suitable for building exterior walls, roofs and other parts.
    • Wall reinforcement: Polyester felt can also be used for wall reinforcement, enhancing the stability and durability of the structure, and is suitable for exterior wall waterproofing and crack repair.

    Application of mesh cloth

    • Wall reinforcement: Mesh cloth is widely used in wall reinforcement projects, providing excellent tensile strength and corrosion resistance. Ensure that the wall is strong and durable, suitable for exterior wall waterproofing and crack repair.
    • Crack repair: Mesh cloth is often used for crack repair, providing initial reinforcement to prevent further expansion of cracks, and is suitable for indoor and outdoor walls.

    Choose the most suitable type of glass fiber for waterproofing

    Choose according to the application environment

    • Outdoor environment: For waterproof projects that are exposed to outdoor environments for a long time, it is recommended to choose glass fiber types with excellent UV resistance and corrosion resistance, such as polyester felt. These materials can maintain stable performance under long-term exposure to sunlight and chemicals.
    • Indoor environment: For indoor waterproof projects, you can choose glass fiber types with higher strength and good flexibility, such as mesh cloth. These materials can maintain stable performance under complex stress conditions and are suitable for waterproofing of walls and floors.

    Choose according to structural requirements

    • High strength requirements: For waterproofing projects that require high tensile strength and compressive strength, it is recommended to choose glass fiber types with higher strength, such as polyester felt. These materials can maintain stability and durability when subjected to large external forces, and are suitable for waterproofing of large structures.
    • Flexibility requirements: For waterproofing projects that require good flexibility and crack resistance, it is recommended to choose glass fiber types with better flexibility, such as mesh cloth. These materials can maintain stable performance under temperature changes and stress, and are suitable for waterproofing under complex stress conditions.

    Choose according to construction conditions

    Simple construction: For waterproofing projects with simpler construction conditions, you can choose glass fiber types that are easy to cut and shape, such as chopped strands. These materials are soft in texture and easy to operate, and are suitable for small-area waterproofing projects.

    Complex construction: For waterproofing projects with more complex construction conditions, it is recommended to choose glass fiber types with higher strength and better flexibility, such as polyester felt. These materials can maintain stable performance under complex construction conditions, and are suitable for large-area waterproofing projects.
