How to do roof waterproofing? Where can I find waterproofing membrane? How much is the roofing membrane waterproof? What's the price of waterproofing membrane? How to represent waterproofing membrane? Top ten brands of waterproof materials, roofing waterproof practices and waterproofing membrane construction methods.

What factors will affect the waterproof effect of waterproofing membrane? Waterproof coiled materials are mostly used in the waterproof construction of roofs, external walls and large areas. Compared with painting waterproof coatings, they have higher efficiency, better puncture resistance, high temperature resistance and corrosion resistance. However, waterproof coiled materials have higher requirements for construction, so if you want to have a good waterproof effect, you must pave the waterproof coiled materials. Next, I will tell you what factors will affect the waterproof effect of waterproof coiled materials.

[Waterproof technology] What factors will affect the effect of waterproof coiled material?

What factors will affect the effect of waterproofing membrane?

Temperature factor:

High temperature can accelerate the oxidative aging of asphalt waterproofing membrane. For some waterproofing membranes with high boiling point, low volatility and good compatibility with asphalt felt, the toughness of asphalt felt can be improved. Too high temperature will also promote the migration of plasticizer, leading to the increase of brittleness and easy fracture of waterproofing membrane.

Roof structural factors:

The roof structure of a building has a great influence on the common waterproofing membrane such as the roof slope. If the roof slope is large, the roof dewatering can make the roof drainage smooth, reduce the contact time between rainwater and asphalt waterproofing membrane, and reduce the probability of waterproofing membrane leakage, thus prolonging the service life of waterproofing membrane.

Rainfall factors:

Rainfall has little direct influence on the performance of waterproofing membrane. For ordinary waterproofing membrane with waterproof effect, more frequent and long-term roof water accumulation will also cause local damage. Especially snowfall, the process of snowfall is accompanied by cooling and long-term melting, which will also increase the brittleness and easy fracture of ordinary waterproof coiled materials.

Construction technical factors:

Improper construction technology is also a factor that causes leakage or damage of roof waterproofing membrane, such as uneven roof base or incomplete cleaning, which makes concrete mixed with other dust to form isolation layer; The leveling layer has low strength and poor quality; The large roof area and unreasonable joint setting will affect the waterproof effect.

Sunshine factor:

The sun is not good for flexible waterproofing membrane. Solar energy increases the temperature of asphalt felt and causes chemical reaction, thus accelerating the oxidative aging of waterproofing membrane, reducing its toughness and brittleness, and easily breaking and leaking.

What factors will affect the waterproof effect of waterproofing membrane? It is closely related to external environment temperature, roof structure, rainfall, construction, sunshine and other factors. Only by paying attention to all aspects, choosing high-quality waterproof coiled materials and professional waterproof construction team can the quality of waterproof projects be guaranteed. Take self-adhesive waterproofing membrane as an example to see several groups of waterproofing membrane products.
