Lightweight Partition Wall Waterproof Board

This panel adopts a classic composite sandwich structure. The surface layer is a high-density, water-resistant calcium silicate panel, which is dense, hard, and has excellent waterproof and seepage-resistant properties, making it less prone to water absorption and moisture absorption. The core material is composed of polystyrene particles and special mortar, making it solid and without voids. This significantly reduces the weight of the panel while firmly ensuring the structural strength of the wall; Compared with traditional wall materials, it is thinner, with an overall weight of only about one-third that of traditional brick walls. This effectively reduces the space occupied by the wall, increases the usable floor area ratio, and significantly reduces the overall load on the building, making it suitable for various new and old building renovation projects without placing an additional burden on the building structure.

In terms of construction technology, lightweight waterproof partition wall panels are installed using a dry method, which is extremely efficient. During installation, first mark the lines on the ground and lay a special adhesive. Stand the panels with tongue and groove joints upright and tighten them, leaving a 10-20mm expansion joint at the top, which is then filled with flexible material and secured to the structural ceiling with U-shaped clips. 24 hours after installation, water and electricity trenches can be cut; Note that the length of the horizontal trench should not exceed 1/2 of the panel width, and the depth should not exceed 1/3 of the panel thickness. After the pipes are laid, fill the trenches with repair mortar. To prevent cracking later, alkali-resistant fiberglass mesh must be applied to the panel joints, followed by two applications of crack-resistant mortar for leveling.

Waterproofing and moisture resistance are the core advantages of this panel, and the key difference between it and ordinary lightweight wall panels. The entire panel undergoes a special waterproofing process, making it non-absorbent, non-efflorescent, and non-mold. Even in long-term exposure to waterlogged and humid environments, it will not soften, deform, or experience strength reduction. In actual testing, when the front side of the board is soaked with moisture, the back side remains dry, eliminating the need for multiple layers of waterproof plastering. This saves on tedious secondary construction steps, reducing material costs and effectively shortening the overall construction period.

Besides its outstanding performance, its construction advantages are also significant.

In terms of functionality, the most prominent feature of this type of board is its superior waterproof and moisture-proof capabilities. Its surface undergoes a special waterproofing treatment, combined with an internal water-repellent foam core, ensuring that even after prolonged immersion in water without any protective finishing layer, the back side remains dry; This completely solves the problems of mold and efflorescence on walls in damp areas such as bathrooms, kitchens, and basements. Currently, the price of mainstream products on the market increases with thickness: 75mm thick boards cost approximately 45-55 yuan/㎡, 100mm thick boards approximately 70 yuan/㎡, and 150mm thick boards approximately 100 yuan/㎡. Users can choose flexibly based on their sound insulation and load-bearing requirements.

As a prefabricated finished panel, it eliminates the need for wet bricklaying and plastering curing, simplifying the process. Two workers can easily handle the handling and installation, making construction several times more efficient than traditional bricklaying; Furthermore, the product contains no formaldehyde or other harmful substances, is environmentally friendly and odorless, meeting modern building environmental standards. It can be used quickly after completion without requiring prolonged ventilation. The panels also possess A1-level fire resistance, anti-aging properties, and corrosion resistance, ensuring stable use in damp outdoor conditions and enclosed underground spaces, with a lifespan far exceeding that of ordinary partition wall materials.

While lightweight waterproof partition walls offer numerous advantages such as fast construction speed (approximately 50% faster than traditional bricklaying), less construction waste, and reusability, attention to detail is still crucial in practical applications. Due to the panel's absorbent surface, it is recommended to apply waterproof coating or tile the surface as soon as possible after installation in extremely humid environments or on walls exposed to water for extended periods (such as shower areas) to prevent moisture penetration and mold growth; In addition, although the panels have a certain hanging capacity, if heavy objects weighing more than 80kg (such as large water heaters or wall cabinets) need to be suspended, steel structure supports must be pre-embedded inside the wall. It is strictly forbidden to rely solely on the strength of the wall itself to bear the load, so as to ensure the safety and stability of long-term use.
