Coastal Breakwater Project in Bali Using Geotextile Fabric for Erosion Control

Geotextile fabric for coastal protection for coastal breakwater projects in Bali is highly suitable for mitigating coastal abrasion and ocean wave pressure.

Unprotected coastlines are susceptible to soil erosion, infrastructure damage, and even a decline in their function as tourist and residential areas. Therefore, coastal protection projects and breakwater construction require geotextile fabric for coastal protection, such as non woven geotextiles.

However, determining the grammage is also a consideration, especially with strong ocean currents that can cause rapid soil loss (erosion). Therefore, non woven geotextiles with a grammage of 500-600 GSM are required. So, how are they applied and how do they function in coastal breakwater projects in Bali?

This article from BaliGEOTEXT will discuss the application of non woven geotextiles in these projects and how to choose a supplier.

Coastal Breakwater Project Challenges in Bali

Bali’s beaches are frequently exposed to ocean waves, tidal currents, and high salt content.

This can cause coastal subsoil erosion and accelerate the degradation of coastal protection structures.

Without proper systems and materials, fine soil is easily carried away by currents, leading to reduced bearing capacity or even breakwater failure.

Therefore, when protecting the coastline, simply using armored stone, concrete, and similar materials is not sufficient.

A supporting layer must be present to control shoreline erosion and protect the coastline, which is why geotextile fabrics are essential for coastal protection.

Function of Non Woven Geotextile for Shoreline Erosion Control

Non-woven geotextiles are geosynthetic materials made from polypropylene (PP) or polyester (PET) through a needle-punching process.

For coastal and marine applications, non-woven geotextiles function as:

1. A separator layer to prevent the subgrade from mixing with the surrounding material.

2. Filtration layer that allows seawater to flow through without carrying soil particles.

3. An additional protective layer serves to protect the subgrade from erosion and scouring.

With these three functions, non-woven geotextiles play a role in shoreline erosion control projects and breakwater construction.

Recommendations for 500-600 GSM Non Woven Geotextile for Coastal Defense

For marine environments with high wave energy, such as in Bali, the use of thin-weight geotextiles is not recommended. This can lead to rapid subgrade erosion (scouring) and joint rupture if continuously exposed to waves.

Therefore, non-woven geotextiles with a 500-600 GSM (GSM) grammage are suitable because they have the appropriate characteristics for coastal defense applications. The following is an example of the role of non woven geotextiles with a 500-600 GSM grammage.

1. High Tensile Strength and Tear Resistance

Non woven geotextiles with a grammage of 500-600 GSM have high tensile strength, allowing them to withstand ocean waves and breakwater pressure.

They also offer superior tear and puncture resistance, especially when installed under riprap.

2. Resistance to Sea Waves

The polypropylene material in nonwoven geotextiles is designed to be resistant to chemicals and high salinity.

This ensures long-term stability and resistance to brittleness, even when continuously submerged in seawater.

This characteristic is crucial in geotextile fabric coastal protection systems.

3. Proper Water Filtration and Land Contour Adaptability

One of the main causes of coastal structural failure is the loss of subgrade due to water flow and ocean/beach waves.

This 500-600 GSM non woven fabric has a porous structure that allows water to pass through the layer without carrying away fine soil particles.

This ensures subgrade soil stabilization and minimizes voids that could potentially become erosion points.

Application in Coastal Breakwater Projects in Bali

In the Bali coastal breakwater project, non woven geotextiles were installed over the leveled subgrade before the stones were placed. The geotextile fabric layer serves as a coastal protection barrier against erosion caused by waves and ocean currents.

The use of 500-600 GSM geotextiles increases the stability of the breakwater structure and extends its service life.

Furthermore, this layer helps reduce the need for long-term maintenance due to the reduced risk of subsidence and structural damage. Non woven geotextiles also help reduce sediment spread during construction. This is suitable for the long term development of coastal defense projects.

Choosing Geotextile Fabric for Coastal Protection in BaliGEOTEX

The use of 500-600 GSM non-woven geotextiles in breakwater projects in Bali is the right step to mitigate coastal erosion and strengthen breakwater structures.

With seawater resistance, strong tensile strength, and additional filtration, separation, and protection functions, geotextile fabric coastal protection systems are ideal.

For coastal areas exposed to high waves, selecting the right geotextile specification with a grammage of 500-600 GSM is crucial. This creates longer lasting protection and supports shoreline erosion control and coastal defense. At BaliGEOTEX, we provide woven geotextiles with a grammage of 500-600 GSM for coastal breakwater projects in Bali to reduce erosion.

BaliGEOTEX also offers customized non woven geotextile specifications for similar projects and other geotechnical projects.
