Introduction of Non Woven Polypropylene Geotextile

 

The Non Woven Polypropylene Geotextile produced by our company is a high-performance and durable synthetic material widely used in various civil and environmental engineering projects. It is often used as a separation, filtration, or reinforcement layer in different geological engineering applications, such as highway and railway construction, slope protection, coastal erosion control, landfill sites, and dam engineering.The width of this Non Woven Polypropylene Geotextile is usually 4-6 meters, and it can also be customized according to your requirements. The weight is 100g-800g and can also be customized.

• Highest quality raw material
• No staples or glues
• Uniform and consistent strength throughout the roll
• No weak spots
• High tensile strength
• High puncture strength
• High temperature resistance
• Screws can pass through fabric without furring up

 

 

 

Benefits of Non Woven Polypropylene Geotextile

 

1. Geotextiles non woven – Lifespan of Geotextile NonWoven is at least 100 years.
2. Thermal and mechanical bonding process ensures superior performance at lower weight and thickness with the benefit of lower transportation costs.
3. The product allows water flows perpendicular to the plane.
4. Suitable for various soil types thanks to a wide range of products of different opening diameters.
5. Excellent mechanical robustness and hydraulic properties.
6. Significant reduction in carbon footprint and cost compared to traditional methods.

 

Common Applications of Non Woven Polypropylene Geotextile

 

Drainage

Geotextiles will efficiently collect surplus water from structures, such as rainwater or surplus water, from the soil and discharge it.

Filtration

Our geotextiles provide superior hydraulic flow and soil retention, which makes them well suited for filtration in subsurface drainage applications and under hard armour systems.

Separation

Geotextiles are used for paved and unpaved roads, where ground conditions have been compromised. As a separation layer, geotextiles can aid preventing the intermixing of dissimilar materials, add to the performance life of the road and reduce the overall thickness of the road section by requiring less aggregate during construction.

Reinforcement

High strength geotextiles can be used to reinforce earth structures as the strength of the tape or filament within the fabric may be increased to suit a specific application. Thanks to their high tensile strength they are an ideal reinforcement solution.

Protection

Due to the consistent thickness and weight of our Geotextiles, they provide adequate cushioning and protection for critical lining systems.

 

How to lay a Non Woven Polypropylene Geotextile fabric?

 

Step one

Prepare the ground. Remove any grass, shrubs, bulbs and large stones.

Step two

Fill any holes left from large stones so that the ground is level and prepped.

Step three

Un roll or un pack fabric purchased earlier.

Step four

Make sure the geotextile is covering the area needed and is laying flat against the soil.

Step five

Secure down with pegs/pins at the edge. Pin tightly to keep the fabric flat and in place. 1 pin per metre along its length.

Step six

If you have overlap from piece to piece remember it needs to be 30-50cm for good coverage. You can also pin at the overlap to secure.

Step seven

Once secured well spread over your next layer e.g. Type 1 or decorative aggregate.

 

How To Choose a Geotextile For Road Applications?

 

For road application, the soil type, rock fill and geotextile itself will interact to produce different results. Getting the balance of these three things right is critical. It is important to note that different site conditions need different solutions. A steep embankment would have different geotextile needs to level road base. Understanding the application and the geotechnical forces at play is key to a successful installation.

Strength ratings

Divided into classes based on their strength. Ranging from class A at the low end through to hardwearing class E geotextiles. Usually, the class would be specified for a project, and this is determined by the size and amount of rock fill to be used.

Soil type

The soil type also has a bearing on which class of geotextile is appropriate, however, soils can generally be classified as either soft or firm. When working with soft soils, typically you need a stronger, thicker geotextile to ensure the fill being placed on top doesn't puncture through. For separation on firmer soils, a thinner geotextile is typically fine as it will not be stretching and moving with loads placed on top.

Fill size

Once you have worked out what size rock fill will be available for your project, you can then select the required geotextile class. The larger and heavier your rock is, the thicker the geotextile will need to be to ensure it doesn't puncture. For pavement stabilisation, rock fill sizes generally fall between 20mm and 150mm, however can be up to 400mm in diameter.
