Method for identifying the quality of waterproof coil

At present, the waterproof material industry is chaotic: the inferior products are flooding the market, and it is not uncommon for companies to lose their credit, such as "stealing the beam for the column" and "shoddy".

Waterproof rubber sheet is widely used in roofing, building walls, tunnels, highways, landfills, etc. It can effectively resist the damage of rainwater and groundwater leakage. It is a kind of flexible waterproof material that can be rolled up. As the first protection to engineering waterproofing, it plays a vital role in the entire project.

Next, we will briefly introduce how to effectively distinguish the quality of waterproof material.

View the product's appearance: check the model, production license, factory name, implementation standards, etc.: Check the product for cracks over 10mm, pay attention to whether the material is bonded.

Looking at the permeability of the base, different types of waterproof  material has different permeability.

Detect the flexibility of the waterproofing material: bend the waterproofing material by 180° to observe if there are cracking phenomenon; stretch the product and check its stretchability.

The problem of waterproof material's quality and safety have occurred from time to time, and there are hidden dangers that endanger people's lives and social and economic development. When you choose a product, you must keep your eyes open, check carefully, and don't be greedy for it is cheap.
