Polypropylene Geotextile
Product Introduction
GEOLEED polypropylene geotextiles are made from 100% high-quality polypropylene fibers using needle-punched non-woven or woven processes. Due to the inherent physical properties of polypropylene fibers, this product exhibits excellent stability in strong acids, strong alkalis, and humid environments.
Core Technological Advantages (GEOLEED PP Series): Compared to commonly available polyester (PET) geotextiles, our polypropylene products offer the following significant advantages:
Superior Alkali Resistance: Polypropylene exhibits virtually no performance degradation within a pH range of 1-14. This makes it the optimal choice for cement-based projects, coastal saline-alkali land, and mine heap leaching.
Low Density, High Coverage: Polypropylene has a density of approximately 0.91 g/cm³ (lighter than water). For the same unit weight, polypropylene fabric is thicker than polyester fabric, providing better protection and cushioning.
Wear-resistant and high-strength: Even when wet, polypropylene fibers retain 100% of their strength, exhibiting excellent puncture resistance and tensile strength.
Environmentally friendly and hydrophobic: Polypropylene does not absorb water and will not increase in weight or deform due to changes in ambient humidity. Furthermore, the material is recyclable.
Working Principle
The working principle of polypropylene geotextile is like putting a “multi-functional protective suit” on the earth, mainly through the following three methods:
1. Soil and water retention (like a "water filter")
It acts like a funnel, allowing water to flow through while retaining the soil. This prevents the silt under the roadbed from being washed away by water, avoiding ground subsidence.
2. Strong support (like "bones")
Burning the fabric in the soil, it firmly holds the sand and gravel, preventing them from shifting. It's like adding "steel bars" to the roadbed, making the ground more solid and able to support the weight of large trucks.
3. Isolation and corrosion protection (like a "protective membrane")
Physical isolation: Separating gravel and soil, preventing them from mixing, making the road less prone to damage.
Chemical resistance: Polypropylene is exceptionally corrosion-resistant. It cannot be damaged by acid rain, alkaline cement, or the saltiness of seawater.

Key Application Scenarios
Landfills and Hazardous Waste Storage Facilities: Polypropylene fabric is used in conjunction with geomembranes as a protective lining to resist corrosion from strong acid and alkali leachates.
Coastal Engineering: Used in ports and breakwaters in coastal areas such as Saudi Arabia and Dubai to resist long-term seawater erosion.
Railway and Road Subgrades: Reduces reflective cracking and improves the frost heave resistance of the roadbed.
Mining: Used as a filter or isolation layer for strongly alkaline mineral slurries in heap leaching processes.
