Standard High Density Waterproof Backer Board
A durable, non-combustible cement-based building panel engineered for moisture-prone environments, providing reliable tile support, dimensional stability, and long-term water resistance. As an ISO-certified manufacturer with over 15 years of export experience, we supply global building material distributors, wholesalers, and commercial construction projects.
Manufactured with a high-density reinforced core structure, these boards provide a stable substrate for ceramic tiles, porcelain tiles, stone finishes, and large-format panels in bathrooms, kitchens, wet rooms, and commercial renovations.
Physical Performance & Core Advantages
Compact Reinforced Core: Engineered to prevent the swelling, softening, and structural degradation common in traditional gypsum-based boards. The dense cementitious composition provides high impact resistance and prevents board deformation under continuous heavy tile loads.
Dimensional Stability: Minimizes expansion and contraction caused by humidity fluctuations. This maintains flat wall surfaces, ensures strong adhesive bond lines, and reduces the risk of tile cracking over time.
High Load-Bearing Capacity: Provides the mechanical strength required for heavy materials, including large-format porcelain tiles, marble, granite, and stone veneer systems.
Fire Safety (Class A1 Non-Combustible): Naturally fire-resistant cement matrix that meets international safety standards for commercial and residential wall systems.
Easy Job-Site Processing: Despite its high density, the board can be scored and cut using standard construction tools. It installs easily with approved corrosion-resistant screws and washers, reducing labor time.

Quality Control & Manufacturing Standards
Every production batch undergoes strict internal verification before packaging:
Raw Material Inspection
Verification of cement grade, reinforcing fiber distribution, and chemical additives.
Dimensional & Thickness Tolerance
Controlled to strict factory standards (+/- 0.5 mm) to ensure flat joints and seamless alignment on site.
Physical Testing
Regular checks on flexural strength (>= 10 MPa), density consistency, and moisture resistance.
OEM, Customization & Supply Chain
OEM & Branding: Support for custom sheet dimensions, private label printing on packaging, and distributor-branded labeling for bulk orders.
Export Packaging: Securely packed on Fumigation-Free wooden pallets with reinforced corner protection and moisture-barrier wrapping to withstand international container transport.
Flexible Supply & MOQ: Standard container loading configurations available for 20ft GP containers. Minimum order quantities vary based on thickness, specification, and custom packaging requirements.
FAQ
Q: What is the main difference between this board and standard gypsum boards?
A: Cement-based backer boards contain no paper-facing layers that can rot or delaminate when exposed to moisture. They offer superior dimensional stability, structural rigidity, and fire resistance in humid environments.
Q: Can this board be installed directly in shower enclosures?
A: Yes. However, because cement boards are water-resistant rather than entirely vapor-proof, a liquid waterproofing membrane or waterproof tape system must be applied over the joints and fastener heads prior to tile installation in continuous-water areas like showers.
Q: What types of tiles can be applied to this substrate?
A: The high-density core supports standard ceramic tiles, heavy porcelain panels, natural stone, marble, and granite, provided appropriate polymer-modified tile adhesives are used.
Q: What are the standard packaging and shipping configurations?
A: Boards are stacked on reinforced wooden pallets, shrink-wrapped, and loaded into standard 20-foot shipping containers for safe global transport. Pallet quantities depend on the board thickness selected (e.g., 6mm, 9mm, or 12mm).
