Haimei waterproof tiles laid by hot air welding can provide good waterproofing effects, mainly due to its advanced installation technology. Hot air welding can firmly connect TPO membranes and steel plates to form a seamless waterproof layer, eliminating common joint hazards in traditional waterproof materials. This welding method not only ensures a secure fit of the membrane, but also enhances the airtightness and water resistance of the entire waterproofing system. Through hot air welding, waterproof tiles can be installed quickly during the construction process, greatly saving construction time and labor costs. Taken together, hot air welding technology makes waterproof tiles excellent in waterproofing effect, construction efficiency and durability, making them an ideal choice for many construction projects.
