4 Tips to Select a Durable Non-Woven Needle Punched Geotextile for Your Ground Reservoir Needs

1. Assess Material Quality

When selecting a non-woven needle punched geotextile, the quality of the material is paramount. Look for fabrics that are constructed from high-quality polypropylene or polyester, as these materials offer excellent durability and resistance to environmental challenges. Research the manufacturer’s specifications for tensile strength, abrasion resistance, and elongation to ensure the geotextile can withstand the conditions of your ground reservoir site.

2. Evaluate Puncture Resistance

Puncture resistance is a critical factor in determining the longevity of non-woven geotextiles. Understand the expected loads the fabric will experience, especially during installation and under mechanical loads. A geotextile with high puncture resistance will not only protect the underlying soil structure from disruption but also maintain its own integrity over time. Look for puncture resistance ratings provided by the manufacturer, as these can offer insightful guidance.

3. Consider Hydraulic Properties

The hydraulic properties of non-woven needle punched geotextiles affect their functionality in ground reservoir applications. Ensure that the material has the appropriate porosity and permeability to facilitate efficient water flow while preventing the migration of soil particles. Conduct a permeability test to confirm that the geotextile will allow for proper drainage without compromising the soil structure. Opt for fabrics that offer a good balance between water filtration and soil retention.

4. Check UV Resistance and Longevity

Since ground reservoirs are often exposed to direct sunlight, it’s essential to select a non-woven geotextile with high UV resistance. Prolonged exposure to ultraviolet rays can degrade many materials, leading to failure and reducing the lifespan of your project. Look for geotextiles that specify UV stabilization in their product descriptions. Additionally, consider the expected lifespan of the fabric based on the environmental conditions it will face, ensuring that it aligns with your project’s longevity requirements.
