High Strength Waterproof Bathroom Backer Board

Engineered for Heavy Tile Installations and Permanent Wet-Area Protection
Our high-strength tile backer board is a rigid, engineered substrate designed specifically for bathrooms, shower systems, wet rooms, spa facilities, and commercial kitchens.

Unlike traditional cement boards that absorb moisture, add heavy structural dead loads, and require specialized masonry tools, our board combines an extruded polystyrene (XPS) core with a polymer cement and fiberglass-reinforced surface. This multilayer composite delivers exceptional compressive strength and complete waterproofing while remaining lightweight, eco-friendly, and clean to install.

High-Density XPS Core (Moisture & Thermal Control)

• Zero Water Absorption: The millions of closed cells in the XPS foam core prevent moisture migration, eliminating internal water retention and subsequent mold growth behind tiled surfaces.
• Dimensional Stability: Minimal thermal expansion and contraction ensure the substrate remains stable under extreme temperature fluctuations, making it ideal for heated bathroom floors and steam rooms.
• Thermal Insulation: The core naturally reduces heat transfer through walls, improving energy efficiency in wellness facilities and steam rooms.

Reinforced Polymer-Cement Surface

• Impact & Load Resistance: Both sides are coated with a high-density polymer cement layer reinforced with alkali-resistant fiberglass mesh.
• High Weight Capacity: This composite skin evenly distributes the concentrated loads of large-format porcelain tiles, natural stone slabs, marble, and granite, preventing grout cracking and tile displacement.
• Superior Adhesion: The textured surface provides an immediate, reliable bond for standard thin-set mortars without requiring priming or extra preparation.

Dust-Free Cutting: The boards can be scored and snapped using a standard utility knife - no abrasive silica dust, no power saws, and a significantly cleaner jobsite compliant with strict global environmental and labor safety standards (such as OSHA guidelines).

Reduced Labor Fatigue: Weighing a fraction of conventional cement boards, they allow for fast, single-person handling, speeding up project turnaround times.

Framing Compatibility: Can be installed directly onto both steel and timber framing using standard corrosion-resistant fasteners and washers.

Optimized Logistics: Reduced weight per square meter translates into lower freight expenses and higher loading efficiency for container shipments.

Minimized Claim Rates: High structural rigidity and permanent moisture resistance drastically reduce callbacks related to tile cracking, loose tiles, or water damage.

Strict Quality Control: Every production batch undergoes automated inspections for thickness tolerance, surface flatness, tensile/bond strength, and water resistance.

We operate automated production lines capable of supporting large-volume orders with consistent batch-to-batch quality.

OEM & Private Label Options: Custom thicknesses, dimensions, edge profiles, customized packaging, barcode labeling, and pallet configurations.

Complete System Integration: We offer matching accessories including waterproof sealing tapes, washers, and specialized screws for a true one-stop shop waterproofing solution.

Certifications & Testing Standards: Manufactured under ISO 9001 quality management systems, with raw materials and finished products complying with recognized international benchmarks (CE, ASTM, and EN standards available upon request).
