In the field of building waterproofing, there are multiple waterproof materials to choose from. Compared with other common waterproof materials, PVC waterproofing membrane has its own distinct characteristics and advantages.
Compared with traditional asphalt waterproofing membrane, the environmental protection performance of PVC waterproofing membrane is more prominent. Asphalt waterproofing membrane often releases some harmful volatile organic compounds during production and use, which has a certain impact on the environment and the health of construction workers. With the continuous improvement of the production process, PVC waterproofing membrane complies with strict environmental protection standards and basically won’t cause such pollution problems.
In terms of the durability of waterproof performance, although the initial waterproof effect of SBS modified asphalt waterproofing membrane is also good, it’s prone to aging, cracking, and other situations over time and with the repeated action of the external environment. PVC waterproofing membrane can maintain stable waterproof performance for a long time relying on its excellent weather resistance and resistance to chemical corrosion, and its service life is relatively longer.
In terms of flexibility, although high-molecular self-adhesive waterproofing membrane also has a good performance, the combination of the flexibility and good tensile strength of PVC waterproofing membrane enables it to adapt to more complex and diverse substrate deformation situations. For example, in the renovation projects of some old building roofs, the substrate may have many irregular deformations. PVC waterproofing membrane can fit the substrate better and ensure the waterproof effect, while some rigid waterproof materials are easily damaged due to substrate deformation.
From the perspective of construction convenience, the construction of waterproof coatings has relatively high requirements for the environment, and it takes a long time for drying and curing after construction. However, the construction of PVC waterproofing membrane is less affected by environmental factors. As long as the substrate is properly treated and the correct construction process is followed, the laying of the waterproof layer can be completed relatively quickly, and subsequent construction can be carried out immediately, greatly shortening the overall project cycle.
Of course, different waterproof materials have their applicable scenarios and advantages. However, after comprehensive comparison, PVC waterproofing membrane shows unique competitiveness in aspects such as environmental protection, durability of waterproof performance, flexibility, and construction convenience, which makes it widely used in many building waterproofing projects.
