FAQ Section
Geotextile and membrane FAQ
Q: What is the primary difference between geotextile and membrane?
A: Geotextiles are permeable fabrics used primarily for filtration and separation, while membranes are impermeable barriers designed for containment and fluid control. Geotextile and membrane can be used together in many applications.
Q: How should I select the appropriate Geotextile and membrane for my project?
A: Consider these key factors: 1) Required tensile strength based on load conditions, 2) Filtration needs (for geotextiles) or impermeability requirements (for membranes), 3) Environmental conditions including UV exposure and chemical resistance, and 4) Installation method compatibility. Geotextile and membrane selection should always be based on project-specific engineering requirements.
Q: What is the typical lifespan of Geotextile and membrane materials?
A: High-quality geotextiles typically last 50-100 years when properly installed, while membranes can last 30-50 years depending on material composition and environmental conditions. For both geotextile and membrane products, actual lifespan depends on factors such as UV exposure, mechanical stresses, and chemical environment.
