As far as waterproofing solutions are concerned, fiberglass mats rank among the most effective materials. Interweave Fiberglass Compound Mat and Fiberglass Nonwoven Base Mat are two widely known products that differ in features and characteristics appropriate for distinct waterproofing methods.
In this article, we will analyze both materials with the aim of helping you make an informed decision to meet your waterproofing requirements in the most effective way.
1. Interweave Fiberglass Compound Mat
What Is It?
Interweave Fiberglass Compound Mat is manufactured by integrating fiberglass strands with either a polymer-modified asphalt or one of the many available waterproofing compounds, resulting in a fortified waterproofing mat. It is a highly flexible and durable construction that is resistant to cracking and water penetration.
Key Features & Benefits
Superior Tensile Strength-Level of Interwoven Fiberglass, structurally excellent in resisting tearing and puncturing.
Flexibility– Withstands movement of structure without cracking.
Waterproof & Weatherproof– Considerable for extensive weather conditions exposure like roofs, basements and foundations.
Best Applications
- Basement tunnels and other structures underground.
- Decks and parking structures on bridges.
- Flat roofs and other roof structures, especially waterproofing.
2. Fiberglass Nonwoven Base Mat
What Is It?
Fiberglass Nonwoven Base Mat is a lightweight, nonwoven fiberglass material often used as an underlayment or base layer in waterproofing systems. It provides reinforcement and stability but typically requires an additional waterproofing membrane or coating.
Key Features & Benefits
Lightweight & Easy to Handle – Simplifies installation compared to heavier mats.
Excellent Adhesion – Bonds well with bitumen, asphalt, and liquid waterproofing membranes.
Chemical & Moisture Resistance – Prevents water seepage and degradation.
Cost-Effective – A budget-friendly option for secondary waterproofing layers.
Best Applications
- Roofing underlayment (before final waterproofing layer)
- Interior waterproofing (bathrooms, balconies)
- Reinforcement for liquid-applied membranes
Which One Should You Choose?
| Feature | Interweave Fiberglass Compound Mat | Fiberglass Nonwoven Base Mat |
|---|---|---|
| Primary Use | Standalone waterproofing | Base layer for waterproofing |
| Strength | High tensile strength | Moderate reinforcement |
| Flexibility | Highly flexible | Less flexible |
| Installation | Torch-applied or self-adhesive | Requires additional membrane |
| Cost | Higher cost | More affordable |
Choose Interweave Fiberglass Compound Mat if:
- You need a direct waterproofing solution without extra layers.
- Your project requires high durability (e.g., roofs, basements).
Choose Fiberglass Nonwoven Base Mat if:
- You need a reinforcement layer before applying liquid waterproofing.
- You’re working on a budget-friendly project with secondary waterproofing needs.
Final Thoughts
Both Interweave Fiberglass Compound Mat and Fiberglass Nonwoven Base Mat play crucial roles in waterproofing systems. The best choice depends on your project’s requirements—whether you need a standalone waterproofing solution or a reinforcing base layer.
