The Role Of Non-woven Fabrics in Waterproof Construction

Jul 19, 2021

In the process of house decoration, waterproofing is a key step. In waterproof construction, we often use polyester non-woven fabrics. Its role is not small. What are non-woven fabrics used for?

It is a fabric without a spun fabric, but the spun short fibers or filaments are guided or randomly supported to form a fiber network structure, which is then reinforced by mechanical, thermal or chemical methods. It has the functions of moisture-proof, breathable, flexible, light, no air intake, easy to decompose, non-toxic, non-irritating, rich in color, low price, and recyclable.

"Three Coating and One Cloth" Process Method


What are the functions of non-woven fabrics?

Our common "three-coating and one-cloth" process, in order to better exert the anti-cracking performance of waterproof coatings, non-woven fabrics are added as reinforcement. The reason why "water is all in" is because there are many small holes in the middle of the concrete. Water will follow these holes and cracks, and if it leaks, the concrete will crack. Due to its moisture resistance, breathability and flexibility, non-woven fabrics can be closely combined with waterproof coatings. At the same time, the more important role of non-woven fabrics for waterproofing is to strengthen and prevent cracks.

How to resist tensile cracking? To give a very simple example, when we are decorating, when there are micro-structure cracks on the wall, the paint and the master will tell us: we need to hang the net to solve it. This net is the glass fiber mesh cloth to improve the resistance. The tension brought by the development of various concrete and putty shrinkage.

Similarly, the non-woven fabric used in the waterproof construction process is also used as a reinforcing material to enhance the tensile performance of the coating, so that the waterproof coating forms a whole and does not leak water.
