Benefits of Nonwoven Compound Base in Waterproofing

By Guanlong Waterproof Materials Co., Ltd

In modern construction, waterproofing systems must be tough, flexible, and long-lasting. One of the most critical components of a reliable waterproofing membrane is the Nonwoven Compound Base—a reinforcement layer that significantly improves membrane performance under stress.

🔍 What is Nonwoven Compound Base?

The nonwoven compound base is typically made of polyester fibers, formed using processes such as needle-punching and thermal bonding. It is widely used as the reinforcement layer in SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene) modified bitumen membranes.

✅ Key Advantages

High Tensile Strength and Elongation
Withstands structural movement, making it perfect for roofing systems, bridges, and tunnels.

Excellent Durability
Resistant to tearing, cracking, and deformation even in harsh weather conditions.

Strong Bitumen Affinity
Offers excellent adhesion to modified asphalt, enhancing long-term waterproofing performance.

Good Rollability
Smooth surface improves handling and installation speed on site.

🏗️ Ideal Applications

Large-scale commercial and industrial roofs

Complex, curved, or uneven surfaces

Below-grade waterproofing: basements, tunnels, foundations

Regions with extreme climates or frequent ground movement
