Polydren PP HT

Polydren PP HT – Non-Woven Polypropylene Geotextile for Waterproofing

Polydren PP HT is a high-performance, non-woven polypropylene geotextile designed for waterproofing applications. It is UV stabilised and features excellent mechanical properties, including high tensile strength and resistance to explosion. Polydren PP HT is used primarily in tunnel waterproofing, both in drill and blast and open-cut tunnel methods, as well as in underground structures. This geotextile is highly permeable and serves as an effective filter and reinforcement layer in waterproofing systems.

Key Features & Benefits

• High Mechanical Strength: Exceptional resistance to mechanical stress and puncturing.

• UV Stabilised: Ensures long-lasting performance even when exposed to the sun.

• High Permeability: Ideal for filtration and drainage in waterproofing applications.

• Explosion Resistance: Suitable for tunnel waterproofing applications.

• Versatile Use: Can be applied in various waterproofing systems, particularly in underground and tunnel applications.

• Easy to Apply: Available in different lengths and widths for site-specific needs.
