Geotextile Solutions

Sludge Dewatering & Marine Erosion Control
Part of an integrated sludge management or marine erosion control program, our High Flow Geotextile Bags are the product of choice for a wide range of challenging applications.

Our Geotextile Tubes are fabricated using high tensile strength, good permeability, high durability, and optimal pore size delivering superior dewatering performance and preventing external environmental shock and damage.

These Geotextile Tube dewatering bags are available in a range of sizes to suit all application requirements, including site restrictions and volume capacities.

APPLICATIONS

  • Sludge dewatering (municipal, biosolids, industrial)
  • Breakwater and bank protection
  • Dams, dikes, and coastal protection
  • Sediment and mining residuals containment
  • Construction site runoff management
  • Marine erosion control

The Geotextile Tube Advantage

How Geotextile Bags Works

The dewatering technology operates in three simple phases making it a practical, low maintenance solution for high volume solids management.
