Geotextile
Geotextile limits geomembrane damage and deformation during installation as well as during subsequent operational use. Geotextile is a needle-punched staple fibre nonwoven for separation, filtration, protection, and drainage.
Geotextile is produced in different "mass per unit area" values like 125-...800-1000-1200 ...gr/m2. Mass per unit area in Geotextile choice depends on different factors like thickness of the geomembrane and height of the waste. CEVKA Construction Co. Ltd helps you to determine required Geotextile type.
Geotextiles are used for different aims;
1. PROTECTION: Nonwoven geotextiles with a high mass per unit area protect geomembranes or pipes against mechanical damage in landfills. Properly selected Geotextiles can safely accommodate heavy dynamic loads and physically aggressive soil conditions.
2. SEPERATION: Intermixing of two dissimilar materials always leads to the deterioration of their engineering performance. The separation function refers to the use of geotextiles to maintain physical separation between two adjacent materials. Geotextiles are ideal for this purpose because of their strength, durability, flexibility and a highly porous structure.
3. FILTRATION: When used as filters, nonwoven needlepunched Geotextiles allow the passage of liquid while preventing the loss of soil particles.
4. ASPHALT OVERLAY: It is common for asphalt pavements to crack prematurely because of design flaws, material limitations or environmental reasons. A fresh layer of asphalt is the most common remedy for this problem. To prevent reflective cracking, a nonwoven needlepunched geotextile must be placed above the cracked surface before placing the new layer. The Geotextile works as a sealant and stress-absorbing layer.
