Polypropylene waterproofing membrane used to be so convenient and easy to use
Polypropylene waterproofing membrane is a multi-layer polymer synthetic sheet. It is made of polypropylene non-woven fabric as the main raw material. It has four layers of reinforced protective layer, anti-aging layer and reinforced layer. The performance can be improved by adding additives. Composite waterproof materials are integrated with sheets to produce polypropylene waterproof rolls.
The fully bonded structure of polypropylene waterproofing membrane can effectively prevent aging under the action of the protective layer, without swelling or horizontal water flow channels. The polypropylene waterproof roll and the foundation layer form an integrated waterproof structure, and are well integrated with the foundation layer of the building, thus integrating with the foundation layer. It can be pre laid and anti sticking, and can be bonded to the concrete poured later as a whole, thus solving the problem of internal bonding (pre laying) waterproofing at home and abroad. Polypropylene waterproofing membrane can be applied on rainy days or on damp and uneven surfaces. No need for primer, low base requirements, saving construction time.
The cement bonding used for polypropylene waterproofing membrane is unique. The characteristics of polypropylene waterproofing membrane are rough surface, uniform and easy to bond. It is suitable for bonding with various materials' base layers and can be directly combined with cement materials during the curing process. This is a performance that other waterproof materials cannot achieve. Polypropylene waterproofing membrane can stably adhere and adhere in a vertical position, can stably adhere and adhere on the casting surface, and can be used for decorative construction on the outer surface. Strong adhesion, the coil overlaps with the coil to form a whole, and its bonding performance is the same as that of the coil.
Polypropylene waterproofing membrane has excellent flexibility and extensibility, adaptability to shrinkage and cracking deformation of the base layer, and unique "self-healing" function. Small holes pierced by sand or nails or microcracks generated under pressure can heal on their own. The cold construction it adopts is safe and environmentally friendly, with no odor, no hidden dangers such as fire, and very safe.
When purchasing polypropylene waterproofing membrane, we need to check its packaging logo and pay attention to the manufacturer's name, trademark, product label, production date, etc. on the packaging. We need to see these clearly. Additionally, it should be noted that the storage period of polypropylene waterproofing membranes usually does not exceed one year.
