Core Advantages of Filament Geotextile for Foundation Engineering
Core Advantages of Filament Geotextile for Foundation Engineering
1. High Strength & Deformation Resistance for Foundation Reinforcement
Filament geotextile features much higher tensile, bursting and tearing strength than staple fiber geotextile. It effectively disperses upper loads, restricts lateral soil deformation, reduces uneven foundation settlement and improves overall bearing capacity. It is especially suitable for subgrades of soft soil and backfill soil.
2. Layer Separation to Prevent Structural Damage
It separates different soil layers, fillers and natural soil of the subgrade, prevents gravel aggregates from piercing soft soil layers, avoids mixing of upper and lower soil layers, stabilizes the thickness of subgrade structural layers, and prevents pavement settlement and cracking in later service.
3. Efficient Drainage & Filtration against Water‑Induced Damage
The three‑dimensional pores of filament geotextile are uniform and stable with fast water permeability and good soil‑filtering performance. It quickly drains accumulated water in the foundation, lowers pore water pressure, blocks capillary water rise, and prevents subgrade boiling, frost heave and piping.
4. Stable Dimension to Adapt to Foundation Settlement
It has uniform longitudinal and transverse strength, low shrinkage and creep. It deforms slowly with foundation settlement without fracture or damage, maintaining stable long‑term performance.
5. Corrosion & Aging Resistance with Long Service Life
Polypropylene filaments are resistant to acid‑alkali, microorganisms and underground corrosion. They remain stable in performance for 50 years when buried underground, reducing later maintenance costs.
6. Convenient Construction to Improve Efficiency
With wide roll width and good integrity, it is easy to lay and overlap. It delivers high construction efficiency for large‑area subgrade projects and shortens construction periods.
