Installation Guide

Here a brief summary of our step-by-step installation of TenCate Geotube® containers.

Step 1:   Grade the site to remove any debris or sharp objects.  (It is important to avoid puncturing the impermeable membrane or the TenCate Geotube® unit.)  Be sure to level site from side to side, with no more than a 0.5% grade from end to end.

Step 2:   Construct a containment berm 1/3 to 2/3 the height of the TenCate Geotube® unit around the perimeter.

Step 3:   Dig trench inside containment berm, sloped for positive drainage to lower end of cell.

Step 4:   Place impermeable membrane over the entire dewatering cell including the interior trench and the perimeter berm.

Step 5:   Place drainage media (such as free-draining granular material or drainage net) over the entire site, except for the interior trench and containment berm.

Step 6:  Unroll TenCate Geotube® unit over the drainage media on the upper end of the dewatering cell.  Align unit using the handling straps.

Step 7:   Install an inline mixing manifold system which includes an injection port, 90-degree elbows for mixing, and a sample port.  Pump sludge through the return line as a final floc check before pumping into the TenCate Geotube® unit.

Step 8:   Connect a flexible line to the filling port.  Pinch valves are the preferred method to control the waste stream.

Step 9:  The circumference of the TenCate Geotube® unit determines the design pump height.  DO NOT exceed the design fill height.

Step 10:   The TenCate Geotube® unit can be filled multiple times during the dewatering process.  [Note:  In colder climates, the freeze-thaw cycle improves dewatering efficiency.]

Step 11:  Simply cut open the container and remove the solid material.
