Description

High-Strength Composite Fabric for Pool and Marine Repairs
This biaxial fiberglass fabric consists of two stitched layers laid at ±45° angle for multidirectional strength. With its flat, non-crimped fibers, it produces a cleaner finish with less distortion and greater mechanical performance than traditional woven cloth.

Perfect for critical repairs and structural reinforcement on concrete, fiberglass, or metal surfaces, especially in high-moisture, chemical-rich environments like pools.
