Provide adaptation suggestions for waterproof backing board materials (polyethylene, polypropylene), thickness and size according to different scenarios such as roof waterproofing, wall moisture-proofing and basement moisture insulation; support free samples for testing waterproof performance and weather resistance (e.g., UV resistance, low-temperature resistance) to meet the needs of different climate zones like Europe, America and Southeast Asia; offer multi-language consultation via English email, Live Chat and WhatsApp, with basic consultation responded within 24 hours and customized solutions provided within 48 hours.

Provide ocean freight service for bulk orders, with arrival at West US ports in 25-30 days and Rotterdam Port (Europe) in 20-25 days, supporting DDU/DDP terms (including customs clearance to reduce buyers' customs clearance difficulty); provide air freight service for urgent orders, with delivery to major cities in Europe and America in 7-10 days, which can be connected to FedEx/UPS dedicated lines; provide logistics tracking numbers (e.g., bill of lading number, courier number) within 12 hours after order shipment, and offer logistics tracking links such as 17Track and ShipBob for users to check the real-time location of goods.

The waterproof backing board provides a 5-year warranty (for waterproof failure and cracking of the material itself), and the warranty scope does not include man-made damage and transportation damage; the warranty process is "provide problem photos + order number, review within 48 hours, and provide free replacement or refund after confirming quality problems"; if the received goods have inconsistent sizes or substandard waterproof performance, free return and exchange are available within 7 days, and the seller bears the round-trip freight (priority is given to replacement to reduce the user's waiting time); regular follow-ups are conducted during the warranty period (e.g., 3 months and 1 year after installation) to provide maintenance suggestions (e.g., "clean the surface regularly to extend the service life").
Our waterproof backing panels utilize high-density waterproof materials, using a multi-layer lamination process and high-temperature pressing to ensure long-term, stable waterproof performance. With a water absorption rate of less than 0.5%, they will not swell or deform in humid environments. They can withstand long-term moisture, humidity, and intermittent submersion, making them ideal for bathrooms, shower rooms, and kitchen walls.
Our waterproof backing panels are lightweight yet strong, allowing for quick cutting with standard cutting tools. Their smooth surface makes them easy to apply tiles or paint, while their seamless edges make them compatible with a variety of wall finishing systems. Installation is quick and easy, using standard screws or specialized adhesives, saving labor and time.
Our waterproof backboards meet international fire protection standards (such as UL 94 and EN 13501) and are flame-retardant and low-smoke, ensuring building safety. Made of non-toxic and environmentally friendly materials, they emit low VOCs and comply with RoHS and REACH environmental regulations, ensuring construction safety and a healthy living environment. Furthermore, the boards are mildew-resistant and antibacterial, preventing the growth of bacteria or mold over long-term use.
