Interweave Fiberglass Compound Mat: The Next Generation Waterproofing Reinforcement

Introduction

As waterproofing standards rise globally, the demand for stronger, more stable reinforcement materials is also increasing. One such innovation is the Interweave Fiberglass Compound Mat—a multi-layer material that combines flexibility, strength, and dimensional stability, making it an ideal choice for modern waterproofing systems.

1. What Is Interweave Fiberglass Compound Mat?
It’s a composite reinforcement material made by interweaving chopped strand fiberglass with polyester or synthetic fibers. This hybrid structure is then bonded using a polymer adhesive or binder, offering high tear resistance and excellent bitumen saturation.

2. Key Features

High Dimensional Stability:
Keeps shape and structure even under extreme heat or load.

Superior Tensile Strength:
Offers excellent resistance to mechanical stress and tearing.

Good Bitumen Compatibility:
Allows full penetration and bonding with asphalt bitumen.

Lightweight & Flexible:
Easier to handle on-site, adaptable to uneven surfaces.

3. Advantages Over Traditional Mats
