Glass Fiber Mesh For Waterproofing
Glass Fiber Mesh for Waterproofing is a high-performance reinforcement fabric specifically engineered for waterproofing systems. It is embedded in waterproof coatings, membranes, and cementitious waterproof layers to prevent cracking, improve tensile strength, and extend the service life of waterproofing systems.
Product Information
GALAXYFIBER glass fiber mesh for waterproofing is made from alkali-resistant fiberglass yarn treated with a special coating. It offers excellent adhesion and compatibility with acrylic, polyurethane, cement-based, and asphalt-based waterproofing materials, making it suitable for waterproofing projects such as roofs, basements, bathrooms, swimming pools, and exterior walls.
Key Features for Mosaic Tile Applications
- Crack Prevention – Effectively resists cracking caused by substrate movement and thermal stress.
- High Tensile Strength – Provides reliable reinforcement for waterproof layers under stress.
- Excellent Adhesion – Bonds strongly with acrylic, polyurethane, cementitious, and bituminous coatings.
- Alkali-Resistant Coating – Ensures durability in cementitious environments.
- Flexible & Conformable – Adapts to complex shapes, corners, and curved surfaces.
- Lightweight – Minimal added weight to waterproofing systems.
- Weather Resistant – Withstands UV, temperature cycling, and moisture.
- Cost-Effective – Reduces maintenance and re-waterproofing frequency.
