A complete wet-area insulation and moisture protection system designed to keep every wall dry, stable, and comfortable for years to come.
More Than Waterproofing — Solving the Root Cause
Traditional waterproof coatings can block liquid water, but they cannot fully stop water vapor from penetrating through tile joints and condensing inside wall structures. Over time, trapped moisture can lead to mold growth, wall seepage, tile failure, and condensation damage — hidden issues that a single waterproof layer simply cannot solve.

Starting from real residential wet-area applications, Earthmother integrates four essential functions into one complete system solution:
- Waterproofing
- Moisture resistance
- Thermal insulation
- Structural reinforcement
The result is a more reliable foundation for long-term comfort and durability.

Engineered for High-Humidity Spaces
Earthmother Yijing Board is a systemized solution specifically developed for bathrooms, kitchens, basements, and other moisture-prone environments. By combining insulation, waterproofing, anti-mold protection, and structural strength into one integrated board system, it helps create dry, stable, and healthier interior spaces.

Key Benefits
1. Blocks Moisture Vapor Penetration
Prevents water vapor from entering wall structures and forming condensation, helping eliminate dampness at the source.
2. Reduces Tile Cracking & Hollowing
Provides a flexible and supportive buffer layer beneath tiles, significantly reducing the risk of cracking and detachment.
3. Eliminates Insulation Weak Points
Extends the whole-house insulation system into wet areas, ensuring continuous thermal protection throughout the home.
4. Long-Lasting Anti-Mold Protection
Integrated antibacterial and anti-mildew additives actively inhibit mold growth within the material itself.

Pure Materials for Long-Term Peace of Mind
The most important parts of a home are often the ones hidden behind the walls. From the beginning of development, environmental safety and material purity were core priorities for Yijing Board.

The board is manufactured using 100% crystal-grade virgin raw materials with zero recycled content, eliminating hidden risks caused by impurities or inconsistent recycled materials.
Using advanced CO₂ foaming technology, the board achieves a closed-cell rate of over 99%, effectively blocking moisture penetration and helping prevent mold formation even in continuously humid environments.
Cleaner materials create cleaner spaces — keeping interiors dry, fresh, and comfortable for the long term.
Five-Layer Reinforced Structure for Lasting Stability
Yijing Board features a high-strength five-layer composite structure that integrates insulation, moisture resistance, waterproofing, and antibacterial performance into one durable system.

Structural Composition
· Core Layer
Made from 100% virgin material, providing inherent insulation, moisture resistance, and anti-permeation performance.
· Dual Alkali-Resistant Fiberglass Mesh Layers
Enhance tensile strength and impact resistance while improving overall structural flexibility.
· Dual High-Strength Polymer Mortar Layers
Reinforced with nano-oxide fibers and advanced anti-bacterial additives for superior water resistance and long-term mold protection.
Designed for long-term performance, the system maintains stability even under continuous exposure to humid conditions.
A Smarter Solution for Modern Healthy Living
Once installed, Yijing Board allows direct thin-set tile application, simplifying construction while improving overall system performance.
Suitable for walls, floors, and ceilings in wet environments such as:
- Bathrooms
- Kitchens
- Basements
- Other high-humidity spaces
From heating insulation systems to complete healthy-home solutions, Earthmother continues expanding from dry areas into wet-area protection — bringing warmth, dryness, and comfort to every corner of the home.
Because every wall deserves lasting protection, and every family deserves a healthier living environment.
