In the field of construction, waterproofing is a crucial aspect that directly relates to the structural safety and service life of buildings. As the key materials for achieving waterproof functions, waterproof building materials come in a wide variety of types with different performances. This article will explore the types, characteristics, and main application scenarios of waterproof building materials, and recommend some high-quality waterproof building materials brands for you.

First of all, waterproof building materials are divided into different types, including waterproof coatings, waterproof membranes, and waterproof sealing materials. Waterproof coatings are liquid-state waterproof materials. They achieve waterproof effects by forming a continuous waterproof film with a certain thickness and elasticity on the surface of the base layer. Common waterproof coatings include polyurethane waterproof coatings, acrylic waterproof coatings, JS composite waterproof coatings, etc. Waterproof membranes are sheet-shaped waterproof materials. They form a continuous waterproof barrier by paving the membranes on the surface of the base layer to achieve waterproof effects. Common waterproof membranes include SBS waterproof membranes, APP waterproof membranes, self-adhesive waterproof membranes, etc. Waterproof sealing materials are used to fill joints, cracks, and other parts of buildings, playing a role in waterproofing and sealing. Common waterproof sealing materials include silicone sealants, polyurethane sealants, polysulfide sealants, etc.
The wide popularity and application of waterproof building materials in the building materials market are closely related to their performance characteristics. Compared with other building materials, they have obvious advantages in waterproof performance. Waterproof performance is the most basic feature of waterproof building materials. High-quality waterproof building materials can effectively prevent water penetration, ensuring that buildings remain dry under various environmental conditions. Generally, waterproof building materials need to be exposed to the natural environment for a long time, so they must also have good durability, be able to resist the effects of factors such as ultraviolet rays, temperature changes, and chemical erosion, and ensure the long-term stability of the waterproof effect. With the continuous development of construction technology, more and more waterproof building materials have the characteristic of convenient construction. For example, waterproof coatings can be directly painted, and waterproof membranes can be paved by self-adhesion or mechanical fixation methods, which greatly improve construction efficiency and reduce construction costs. In addition, in today's society, people's awareness of environmental protection is getting stronger and stronger, and waterproof building materials with good environmental performance are increasingly favored by the market. These materials basically do not contain harmful substances and will not cause harm to the environment and human health.
Waterproof building materials can be seen everywhere in our lives. For example, you can see them in the following places:
In ordinary residential buildings, roof waterproofing is related to the living experience of top-floor residents. For flat roofs, SBS waterproof membranes or polymer waterproof membranes are often used, and they are constructed by hot-melt method or mechanical fixation method. For pitched roofs, waterproof coatings such as acrylic waterproof coatings may be used. They are easy to construct on complex roof structures to form a complete waterproof film and prevent rainwater from seeping into the house.
Bathrooms: Bathrooms are areas with frequent water use, and polyurethane waterproof coatings are widely used. Both the floor and walls need to be well waterproofed. For key parts such as floor drains, corners, and pipe roots, they are first sealed with sealant, and then coated with waterproof coatings. The height of wall waterproofing is generally not less than 300mm, and in the shower area, the wall height is not less than 1.8m. It is applied in multiple layers to ensure that the thickness meets the standard and prevent seepage from affecting the residents downstairs.
Shopping malls: Large shopping malls have large roof areas and high waterproof requirements. Usually, SBS waterproof membranes or APP waterproof membranes are used. Their good weather resistance and anti-aging properties can ensure the long-term waterproof effect of large-area roofs. For underground parking lots, waterproof membranes and waterproof coatings need to be combined, such as self-adhesive waterproof membranes with polyurethane waterproof coatings. Multiple defense lines are used to resist the penetration of groundwater and rainwater, ensuring that the parking lot is dry and preventing vehicles and equipment from being damaged by moisture.
Hotels: In addition to the waterproofing of conventional areas such as roofs, bathrooms, and kitchens, the waterproofing of the swimming pool area in hotels is of great importance. The walls and bottom of the swimming pool are generally constructed with waterproof mortar combined with waterproof coatings, such as JS composite waterproof coatings, to ensure that the swimming pool can store water for a long time without leakage. At the same time, waterproof building materials need to have good water resistance and chemical corrosion resistance to adapt to substances such as disinfectants in the swimming pool water.
Hospitals: Areas such as operating rooms and medicine storage rooms in hospitals have strict waterproof requirements. The floors and walls of operating rooms need to use materials that are environmentally friendly, antibacterial, and have good waterproof performance, such as specially formulated polyurethane waterproof coatings. These coatings can not only meet the waterproof requirements but also ensure the cleanliness and hygiene of the indoor environment and prevent the growth of bacteria. The medicine storage room must ensure the waterproof effect to avoid the dampness and failure of medicines.
Schools: Buildings such as teaching buildings, canteens, and gymnasiums in schools all have waterproof requirements. The waterproofing of the roofs and bathrooms of teaching buildings is similar to that of ordinary residential buildings. The key points of waterproofing in the kitchen area of the canteen are the floors and the walls around the sink and dish-washing sink. For parts such as the indoor swimming pool and roof of the gymnasium, appropriate waterproof building materials and construction techniques are selected according to different structures and functions to ensure the long-term normal use of the building.
Bridges: Bridges are exposed to the natural environment for a long time, subject to the influence of rain, sunlight, temperature changes, etc. For bridge deck waterproofing, waterproof membranes such as SBS waterproof membranes are usually used. Their good elasticity and anti-aging properties can adapt to the expansion and contraction deformation of the bridge structure, prevent rainwater from seeping into the bridge interior, corroding structural components such as steel bars, and ensure the safety and service life of the bridge.
