Geobag Dewatering Bags

Chatoyer geobag dewareting bag discharging on grass

Geobags are also known as dewatering bags, sediment pump bags and sediment filter bags. They are perfect for filtering sediment laden water. Geobags provide a simple yet effective method of removing heavy particles from excavation water allowing silt free water to be released from the bag.

Chatoyer manufactures a range of sizes for smaller applications and can custom designs for large sediment control operations. Our designs include options for various types of filter bags and filter tubes. We utilise either a non woven geotextile for gravity, or low pressure fed dewatering or a woven geotextile for high pressure dewatering scenarios.

Dewatering bags can be used within construction or mining activities for incidental dewatering applications (such as after rain events), dewatering dredged material, or dewatering sludge from waste water treatment.

Geobag effectiveness and maximum capacity will depend on a number of factors including type of sediment, temperature and the geotextile. Our engineering team will work with you to design Geobags that meet your site and project
