Why is there still leakage despite the waterproof membrane in Yunnan being properly installed?
Release date:
2020-11-19
Now Yunnan Pu'er Waterproof Board It is now gradually being widely applied—but how much do we really know about the causes of waterproofing leaks? After all, once we’ve properly installed the waterproofing system in underground structures like tunnels, Yunnan Pu'er Waterproof Board In the future, waterproof boards made in Yunnan's Pu'er sometimes experience leakage issues—so why is that? Yunnan Pu'er Waterproof Board Will there be leaks? Now, let me give you a detailed introduction.
1. Yunnan Pu'er Waterproof Board The material itself cannot adhere tightly to the initial shotcrete lining, and impacts during installation, as well as protruding elements on the back side, can easily puncture the Yunnan Pu'er waterproof membrane, leading to water leakage.
According to industry experts specializing in rooftop waterproofing, the joints between individual panels are the system's weakest link—any carelessness could lead to the failure of the entire waterproofing system.
If the concrete wall surface has significant voids and uneven areas, the compression from the secondary lining and deformation of the surrounding rock can cause stretching of the Yunnan Pu'er waterproofing membrane—particularly at the joints, where fracture damage is likely to occur.
II. According to experts specializing in waterproofing, underground construction sites often have limited working spaces, making it challenging to achieve the designed impermeability requirements through thorough concrete compaction. Additionally, construction joints and expansion joints remain vulnerable weak points in such waterproofing measures.
3. Spraying Yunnan Pu'er Waterproof Board It is difficult to ensure uniformity, as although the coating material typically has good ductility, it exhibits relatively low tensile strength. If subjected to significant external forces, the structure may deform and shift, easily leading to cracks in the waterproof membrane and ultimately causing the entire waterproofing system to fail. Additionally, this construction method demands high precision in the spraying process—precision that is often challenging for most projects to achieve.
4. Due to Yunnan Pu'er Waterproof Board Material degradation significantly contributes to the failure of waterproofing systems. This is primarily due to the weakening of waterproof materials caused by groundwater exposure and microbial erosion, as well as the inherent vulnerabilities in existing waterproof materials that gradually diminish over time, especially under harsh environmental conditions and prolonged use.
5. Underground structures are constantly exposed to complex environmental conditions, creating numerous adverse factors that can lead to structural deformation. Once these deformations occur, the lining structure may experience displacement and distortion, cracking, concrete spalling, and other issues—ultimately compromising the integrity of the waterproofing system. As a result, Yunnan Pu'er Waterproof Board Leakage.
Yunnan Pu'er Waterproof Board Due to the nature of the production materials, fire safety must be prioritized during storage and construction. Here are some specific fire prevention measures:
First, enhance fire safety awareness among construction site workers and ensure they are proficient in using equipment such as fire extinguishers.
Second, ensure that an adequate number of fire extinguishers are provided as required;
Third, the construction area for Yunnan Pu'er waterproof boards should be separated from residential areas to prevent open flames.
Fourth, avoid randomly wiring or running cables haphazardly, as well as covering wires with PVC pipes.
