Clean dust and oil before construction to make that the corner code is clean, so as to ensure the bonding effect between the corner code and the waterproof breathable film. When the corner code passes through the waterproofing membrane sheet, the integrity of waterproof film should be kept as far as possible. The waterproofing membrane curve will be flooded and completely sealed between the corner code and the the body of waterproofing membrane. 
When connecting with window and door frame, the waterproofing membrane linear should adopt flooding seal. For the corner, it should be sealed by film curve. The bonding width of sealing window and door frame is not less than 2cm, and corner bonding width is not less than 10cm. 
In the construction of roof, the laying of waterproof film should be along the water flowing direction on the roof, and the lap waterproof film length of is 10cm. When the high-strength aluminum alloy bracket of the roof passes through the waterproofing membrane, the intersection of the aluminum alloy bracket and waterproofing membrane should be sealed with butyl rubber strip around a circle.

What is Waterproofing Membrane Used For?

Waterproofing membranes are essential components in construction and building maintenance, offering a protective layer to shield structures from water damage. These membranes are typically applied to surfaces that are susceptible to water exposure, such as roofs, basements, walls, and foundations, to prevent water ingress that can lead to costly repairs and structural failures.

The primary function of a waterproofing membrane is to create a watertight barrier over surfaces. This barrier not only prevents water from seeping into buildings but also protects against dampness and the growth of mold and mildew, which can compromise indoor air quality and building materials. By doing so, waterproofing membranes extend the life of a structure and enhance its durability against environmental challenges.

Additionally, waterproofing membranes are utilized in various applications beyond typical residential and commercial buildings. For instance, they are critical in protecting infrastructure such as bridges, tunnels, and parking structures which are often exposed to harsh environmental conditions. These membranes also play a vital role in water conservation projects, such as artificial ponds and reservoirs, ensuring that precious water resources are retained efficiently and sustainably.

The versatility and protective qualities of waterproofing membranes make them indispensable in construction, contributing significantly to the longevity and safety of structures while ensuring a healthier living and working environment.

What is Waterproofing Membrane Made Of?

Waterproofing membranes are crucial in construction for preventing water damage, made from diverse materials tailored to specific environmental conditions and building needs.

One prevalent material is modified bitumen, valued for its durability and flexibility, making it ideal for high-stress areas like roofs. It excels in resisting extreme temperatures and wear, serving well in both residential and commercial settings.

Ethylene propylene diene monomer (EPDM) rubber is another popular choice. This synthetic rubber stands out for its longevity and versatility, resistant to weather changes, UV rays, and severe weather, making it perfect for exposed structures such as rooftops and outdoor decks.

Polyvinyl chloride (PVC) is favored for industrial uses due to its chemical resistance, light weight, and ease of installation. It's also non-flammable and inhibits biological growth, enhancing its durability.

Thermoplastic polyolefin (TPO) and liquid-applied membranes are emerging as eco-friendly options. TPO is noted for its energy efficiency and heat-reflective properties, while liquid membranes provide a seamless, adaptable barrier that fits complex architectural designs perfectly.

These materials ensure that waterproofing membranes effectively protect buildings from water ingress, maintaining structural integrity and longevity.

What are the Disadvantages of Waterproofing Membrane?

While waterproofing membranes provide significant benefits in protecting structures from water damage, there are several disadvantages associated with their use that need to be considered during the planning and installation stages.

Cost and Installation Complexity: One of the primary drawbacks of waterproofing membranes is their cost. High-quality membranes can be expensive, and the cost increases with the complexity of the installation. Professional installation is often required to ensure that the membrane performs effectively, which adds to the overall expense. The installation process itself can be time-consuming and requires precise workmanship to avoid failures, such as leaks and breaks in the membrane.

Maintenance and Repair Challenges: Over time, waterproofing membranes may degrade due to environmental factors like UV exposure, extreme temperatures, or mechanical damage. Once damaged, these membranes can be challenging and costly to repair. The entire section of the membrane often needs to be replaced to ensure integrity, which can disrupt the use of the building and result in significant maintenance costs.

Compatibility Issues: Not all waterproofing membranes are compatible with all surface materials. Chemical incompatibility between the membrane and the substrate can lead to adhesive failures or degradation of the membrane. It is crucial to select the right type of membrane for the specific materials used in the construction to avoid such issues.
