1. Understanding Geotextile 150g/m²
Geotextiles are permeable synthetic fabrics designed to interact with soil, rock, or other geotechnical materials. The “150g/m²” designation refers to the weight of the material per square meter, indicating a balance between durability and flexibility. Typically made from polypropylene or polyester fibers, this grade is produced through either woven or nonwoven techniques:
1.1. Nonwoven Geotextile 150g/m²
Created through needle-punching or thermal bonding, nonwoven geotextiles excel in filtration and separation tasks due to their random fiber orientation and porous structure. These geotextiles are especially effective in applications where water needs to flow through the fabric while separating different soil layers.
1.2. Woven Geotextile 150g/m²
Woven geotextiles are produced by interlacing yarns in a grid pattern. These versions prioritize tensile strength and load distribution, making them ideal for reinforcement applications. The woven structure enhances their performance in scenarios where higher stress is expected.
1.3. Key Technical Properties of 150g/m² Geotextile
The 150g/m² geotextile offers a unique combination of physical characteristics that make it versatile for various applications:
- Thickness: 0.8–1.2 mm (depending on manufacturing method)
- Tensile Strength: 8–12 kN/m (machine direction)
- Elongation at Break: 30–50%
- Permittivity: 0.8–1.2 sec⁻¹
- Puncture Resistance: 300–500 N
- UV Resistance: 70% retained strength after 500 hours of exposure
These metrics position the 150g/m² geotextile as a mid-weight solution suitable for projects requiring moderate load-bearing capacity without sacrificing permeability.
2. Strategic Applications Across Industries
The 150g/m² geotextile has found applications in various industries, demonstrating its versatility and functional advantages:

In road construction, the 150g/m² geotextile prevents the intermixing of subgrade soil and aggregate base layers, effectively stabilizing the roadbed. A study in Texas conducted in 2023 showed a 40% reduction in pothole formation when using this geotextile as a separation layer beneath asphalt, improving the road’s longevity.
2.1.2. Railway Track Bedding
Installed between ballast and sub-ballast layers, the 150g/m² geotextile minimizes track settlement while enabling efficient drainage, crucial in high-speed rail systems. It ensures the stability of the tracks by providing a solid foundation and preventing moisture accumulation.
2.2. Agricultural Innovation
2.2.1. Erosion Control in Sloped Farmland
Farmers in hilly regions have embraced this geotextile as a biodegradable alternative to plastic sheeting. When combined with vegetative growth, it reduces soil erosion by up to 85% during monsoon seasons, promoting sustainable farming practices.
2.2.2. Greenhouse Drainage Optimization
Dutch horticulturists use the fabric beneath greenhouse floors to create capillary breaks. This helps prevent waterlogging while maintaining the integrity of the soil structure, thus supporting healthy plant growth.
2.3. Environmental Engineering
2.3.1. Landfill Liners
In landfill applications, the 150g/m² geotextile serves as a protective layer above geomembranes. It resists punctures from sharp waste materials while facilitating the collection of leachate, making it an essential component of modern waste management practices.
2.3.2. Constructed Wetlands
In wastewater treatment systems, geotextiles like this one provide a substrate for microbial growth while preventing the clogging of drainage pipes. This application is especially crucial for sanitation projects in developing nations, improving water quality and promoting environmental sustainability.
2.4. Coastal Management
2.4.1. Dune Stabilization
Coastal engineers in the Netherlands have embedded this geotextile within sand dunes to create erosion-resistant matrices. These matrices are designed to withstand the fierce storms of the North Sea while supporting the regrowth of natural vegetation.
2.4.2. Mangrove Rehabilitation
During mangrove replanting initiatives in Southeast Asia, the 150g/m² geotextile stabilizes muddy substrates until saplings can establish their root systems, contributing to the restoration of vital coastal ecosystems.
2.5. Urban Landscaping
2.5.1. Green Roof Systems
As part of multi-layered green roof assemblies, this geotextile provides root protection and drainage functions without adding excessive weight—a vital consideration for retrofitting urban buildings.
2.5.2. Permeable Pavement Subgrades
Municipalities in water-stressed regions install this geotextile beneath permeable concrete to enhance filtration rates while preventing fine soil migration. This contributes to better stormwater management and supports sustainable urban development.

5. Installation of 150g/m² Geotextile
The process of installing geotextiles is akin to putting a “protective suit” on the land. The installation procedure includes several key steps:
5.1. Site Preparation
The site should be cleaned thoroughly to remove weeds, debris, and other obstructions. This ensures that the geotextile can be laid flat and without any hindrance.
5.2. Geotextile Laying
The geotextile should be laid flat on the prepared ground, ensuring it is straightened and wrinkle-free. This is crucial for the material to perform its intended function effectively.
5.3. Compacting and Fixing
Once the geotextile is laid, it should be compacted using a special roller or manually. It should also be fixed in place with nails or straps to prevent any shifting during subsequent operations.
5.4. Covering and Protection
Finally, the geotextile should be covered with a layer of soil or other protective materials to shield it from damage and ensure its continued effectiveness.
6. Judging the Quality of Geotextiles
The quality of geotextiles can be evaluated using several methods:
6.1. Appearance
A high-quality geotextile should have a smooth surface, uniform color, and no visible impurities or damage.
6.2. Material Check
The material can be verified through the product manual or by consulting with the manufacturer or supplier.
6.3. Performance Testing
Professional testing equipment should be used to assess the geotextile’s various properties, ensuring it meets the required standards for strength, durability, and permeability.
7. Conclusion
