Triaxial Fiberglass Felt & Mesh Composite Fabric
Triaxial Fiberglass Felt & Mesh Composite Fabric is a dedicated reinforcement composite for waterproofing. It balances rigidity and flexibility while resisting deformation and delamination, far outperforming single-material alternatives.
Description
Product Information
GALAXYFIBER Triaxial Fiberglass Felt & Mesh Composite Fabric combines fiberglass mat (providing a uniform impregnation matrix and isotropic reinforcement) and woven fiberglass cloth (providing a high-tensile warp and weft skeleton). The all-fiberglass system delivers extremely high tensile strength, absolute dimensional stability, and superior high-temperature and weather resistance. It is widely used for membrane overlap sealing, fine crack bridging, detail reinforcement at pipe roots and corners, and local repair in high-demand waterproofing projects.
Key Features for Mosaic Tile Applications
- All-fiberglass system, ultimate dimensional stability. The combination of fiberglass felt and mesh undergoes virtually no shrinkage or stretching during heating and bitumen impregnation, ensuring absolute flatness and preventing edge curling during application.
- Multi-directional reinforcement, no weak diagonals. The mesh is distributed at 0°, +75°, and −75°, dispersing tensile and shear stresses across three axes and effectively preventing the deformation concentration and tearing that conventional biaxial meshes exhibit under diagonal loading.
- Ultra-high tensile strength and rigid skeleton. The fiberglass mesh provides strong multi-directional tensile capacity, while the felt provides uniform mechanical reinforcement. The composite withstands extreme mechanical and substrate cracking stress.
- Superior high-temperature and weather resistance. Made of pure inorganic fiberglass, it not only withstands high-temperature impregnation of modified bitumen but also exhibits excellent corrosion and aging resistance under long-term UV, humidity, and heat conditions, ensuring a long service life.
- Rapid impregnation and no bitumen leakage. The porous structure of the fiberglass felt provides abundant penetration channels for bitumen. This ensures firm bonding with the mesh skeleton; the felt layer covers the mesh, effectively preventing bitumen leakage and mesh imprinting during construction.

Products Applications

Sealing and reinforcement of membrane lap edges

Localized reinforcement at complex junctions

Spot repairs for heavy-duty waterproofing projects
Usage Precautions
- Bitumen temperature control. To ensure impregnation, hot asphalt temperature must be controlled within the process range (typically 160-180°C).
- Edge protection. The mesh edges are relatively rigid and may have slight fraying after cutting. Use hot-melt or special tools to press them flat during construction to avoid scratches.
- Avoid excessive folding. All-fiberglass materials are rigid. When applying at corners, it is recommended to cut and overlap. Excessive sharp folding may cause internal fiberglass breakage, affecting local strength.
- Centered application. When bridging cracks, ensure the crack or overlap is centered under the tape to guarantee sufficient coverage on both sides.
Product Components
Fiberglass felt acts as a matrix, providing impregnation channels.
Triaxial fiberglass mesh acts as a strong skeleton, providing multidirectional tensile strength.
Quality Control

Mass per unit area deviation
Multi-directional tensile breaking strength
Composite bonding (anti-delamination)
Impregnation
Mesh distribution uniformity, width deviation, and slitting flatness.
Packaging and Transportation
Roll packaging, wrapped in plastic film for moisture and rain protection. Avoid heavy pressure causing deformation during transportation. Fiberglass materials must be protected from sharp objects puncturing the packaging.
