The moisture-proof, air permeability and flexibility of non-woven fabrics(China Needle Punch Non Woven Fabric Supplier) make it possible for non-woven fabrics to combine closely with waterproof coatings. At the same time, non-woven fabric for waterproofing more important role is to strengthen the role of anti-cracking.

How to resist tension crack? For example, when we are decorating, when there are slight cracks in the wall, the painter will tell us: to hang the net to solve, this net is glass fiber mesh cloth, used to resist the tension caused by the shrinkage of concrete and putty.

Similarly, non-woven fabrics(PET Needle Punch Non Woven Fabric Company) used in waterproof construction are also used to strengthen the tensile properties of coatings, so that the waterproof coatings form a whole, so as not to leak water.

"One cloth, three coatings" process

Concrete cracks, and there are many small holes in the middle of concrete, water will follow these holes and cracks, leakage, so there is the "water is all-pervasive" argument.

In order to make the waterproof coatings more resistant to water intrusion, intelligent waterproof people invented waterproof coatings, and in order to better play the anti-cracking performance of waterproof coatings, non-woven fabric(Needle Punch Non Woven Fabric Vendor) was added as reinforcement. Therefore, we have common "one coat, three coats" and "two coats, five coats" and other processes.
