Waterproof Plastic PP Sheets With Excellent Performance In Construction Projects
PP material has a stable molecular structure. Our PP sheets are not easy to decompose harmful substances under normal temperature and general usage conditions, nor does it easily react with ingredients such as acids, alkalis, and oils in food, thus effectively preventing food from being contaminated. The core advantages of PP boards in waterproofing projects are significant. As a polymer material, it has a stable molecular structure and excellent water resistance.
Core Performance
Our products do not absorb or seep water, and will not expand, deform or rot even after long-term immersion, thus being able to block water penetration persistently and reliably. Meanwhile, it has strong chemical corrosion resistance, capable of resisting erosion from rainwater, groundwater, acid-alkali solutions, etc., making it suitable for complex environments such as around chemical plants and sewage treatment plants. PP boards that have undergone special treatment boast good anti-aging and weather resistance properties. They can withstand exposure to sunlight and temperature changes ranging from -20℃ to 60℃, are not prone to cracking or embrittlement, and have a service life of 10-20 years, which can reduce later maintenance costs. In addition, PP boards have a low density (about 0.9-0.91g/cm³), so they are lightweight and easy to transport. They can be quickly spliced by means of welding, bolt fixing, etc., featuring convenient construction. They are suitable for various scenarios such as roofs, basements, and wall surfaces, and are also friendly to buildings with low requirements on the load-bearing capacity of the base layer.
Multiple Applications
PP boards find extensive application in waterproofing projects. They can be directly laid on roof substrates as the core waterproofing material, making them ideal for flat roofs, sloped roofs, and terraces. When paired with insulation layers, they serve dual purposes of waterproofing and thermal insulation, suitable for civil residences, factories, and other structures. For basements and underground garages, they are used to waterproof walls, floors, and base slabs, effectively resisting pressure-driven groundwater infiltration and preventing dampness and leaks. Their strong corrosion resistance also makes them suitable for areas with high groundwater levels or corrosive components in the soil.
In water tanks and reservoirs, PP boards function as inner waterproof linings for drinking water tanks, fire-fighting pools, and sewage treatment tanks. Their non-toxic and water-resistant properties ensure water quality remains uncompromised while protecting tank structures from water erosion. They work well as waterproof layers for interior walls in bathrooms and kitchens, preventing moisture penetration that could cause mold or peeling. When embedded in external wall structures, they act as invisible waterproof barriers to enhance impermeability.
For tunnels and culverts, PP boards are laid on inner walls to resist groundwater and rainwater infiltration, safeguarding structural stability—particularly useful in humid environments like transportation tunnels and hydraulic culverts. Additionally, they serve as waterproof coverings for temporary structures, tents, and prefabricated houses, enabling quick setup of temporary waterproofing facilities to handle emergencies such as sudden rainstorms.
