A geotextile dewatering bag is a filter bag made from water-permeable geotextile fabric designed to separate water from mud, waste, or other solid sediments. These geotextile bags come in a wide range of sizes, from small, medium, to very large or macro sizes. Let’s take a closer look at these bags, their sizes, and their price range.
What Is a Geotextile Dewatering Bag and How Does It Work?
A geotextile dewatering bag is a bag made from geotextile fabric that functions to separate water from sediments like mud, waste, sand, debris, and more. The bag is porous and allows water to pass through while trapping solid sediments inside. This way, only clean water can escape from the bag.
These geotextile bags have a ton of uses because they’re really versatile. For example:
- Waste Treatment
These bags can help separate water from industrial waste or sludge, leaving the solid waste inside the bag. This makes it easier to dispose of or further process the waste.
- Construction Projects Near Water
Another example is in construction projects near bodies of water, where these bags can filter water from muddy or dirty foundation or embankment excavations. This turns dirty water clean, making it safer for the aquatic environment.
- Coastal Erosion Control
Another use is to control coastal erosion. We can fill these bags with sand along the shoreline as barriers or wave breakers, which helps prevent erosion that could threaten the coast and marine ecosystems.

How It Works
The way a geotextile dewatering bag works is actually pretty simple. Here’s a quick rundown:
- First, you fill the bag with a mixture of water and solid materials like sand, waste, sludge, or other materials. Usually, pumps are used for this filling process.
- The water contained in the material will flow out of the bag. Meanwhile, the solid materials will stay inside the bag because they can’t pass through the geotextile fabric.
- As the water flows out, the volume of material in the bag decreases, allowing the filling cycle to continue until the bag reaches its full capacity.
- After the drying process is complete, the bag becomes a final storage for the solid materials, which can then be used as needed, disposed of, or further processed.

Size and Price
Geo bag size and price actually vary quite a bit. There are small, medium, large, and even extra-large sizes. Here are some examples of small to medium bag sizes and their price ranges:
- 40 cm x 80 cm costs around $0.15 – $0.40 per bag.
- 70 cm x 50 cm costs around $1.30 – $1.50 per bag.
- 35 cm x 66 cm military standard costs around $3.50 – $11.00 per bag.
Examples of larger bag sizes are as follows:
- 145 cm x 240 cm can cost $17.00 – $20.00 per bag.
- 80 cm x 120 cm costs around $5.00 – $7.50 per bag.
- Heavyweight sizes with a capacity of approximately 174 kg can cost $100 – $150 per bag.
For very large bags, examples include:
- 1.2 m x 1.2 m up to 6 m x 4 m with prices ranging from $5.40 – $54.00 per square meter.
Geo bag size and price really vary a lot. Usually, the bigger the bag and the better the material, the higher the price can be. The many size options are also really convenient because they let users pick the geotextile bag that best fits their needs.
