TenCate Geotube® Dewatering Technology offers the advantage of stacking TenCate Geotube® units in layers.  Stacking is beneficial for dewatering projects that involve large volumes of sludge to dewater and/or when a limited footprint is available for the dewatering cell area.  Stacking TenCate Geotube® containers requires the owner, engineer, and operator to consider issues that are unique with stacking, and to follow all steps that contribute to a safe and successful operation.

TenCate is the industry leader in dewatering innovations, including the incorporation of container stacking use in dewatering projects.  We have conducted tests involving the stacking of TenCate Geotube® containers and studied the best methods for successful dewatering.  We've learned that the preparation of a site is extremely important and that dewatering times and compaction levels are key elements.  For further information on the use of stacking in a dewatering project, contact your TenCate Market Manager to discuss your specific situation. 

TenCate has developed proprietary software, TenCate Geotube® Stacking Analyzer, to assist their customers and contractors with stacking issues.  The TenCate Geotube® Stacking Analyzer identifies the potential stresses on the TenCate Geotube® units and offers a variety of stacking solutions.  Our Market Managers work closely with customers to design projects that protect the integrity of the dewatering structure.

Below is a list of the minimal elements to be considered before stacking of TenCate Geotube® units is implemented in a dewatering project.

  1. Site stability
  2. Filtrate flow and control
  3. Stacking design and sizing of TenCate Geotube® layers
  4. Manifold feed system
  5. Safety and operation
  6. Dewatering time between layers
  7. Placement of second and subsequent layers
  8. Solids removal
