Product Introduction
Bituminous waterproofing membrane is a reliable and durable method of preventing water infiltration in buildings. Its ability to withstand different weather conditions, along with its flexibility and easy application, make it an ideal choice for many building projects. Regular maintenance and inspection of the membrane can help to ensure its longevity and prevent leaks from occurring.
Product Features
The characteristic of fire-baked waterproof coil is that it is completely bonded with the bottom layer, even if it is partially damaged, it will not conduct water, so it is very important to ensure the quality of complete bonding. Because the characteristics of the coil are self-adhesive, it is easy to glue during the operation, that is, when the coil of the insulating paper is uncovered, it has been bonded on the bottom surface, and there is often uneven diffusion, foaming and other phenomena.
