Frequently Asked Questions

Connecting you to our field expert and technical director, Dean Wickoren, we answer some of the most common questions regarding the use, installation and purpose of ENVIROTUBES from the expert himself.

If you have any other questions you feel we should address, please email us.

How long does it take an ENVIROTUBE to dewater enough to haul away?
It does depend on the fill material, but if the chemistry is right most materials are ready to haul away in 5 to 10 days.

How dry will the material get?
Given enough time it will become the consistency of corn flakes.

Can envirotubes be reused?
No

Why not?
The fabric cannot be re-sewn.
The fabric stretches and changes weave shape when pumped repeatedly.
The fabric which ENVIROTUBES are made from can often be used for applications other than ENVIROTUBES.

How much do ENVIROTUBES cost?
That depends on the shrink rate of the material. The more the fill material shrinks the less the ENVIROTUBES cost for the job.

How clean is the run-off water?
As clean as you want it. The lower the TSS, the more care during filling and the better the chemistry [polymer] has to be.

How long between fillings?
Again, this depends on the material and chemistry. It is recommended that you wait several hours.

Where can I get the polymer and feed pump?
We will be more than happy to recommend suppliers but we do not sell polymers.

How long have geotextile tubes been used and what materials can they contain?
Since the late 1980's, several thousand geotextile bags, tubes and containers ranging in sizes from 1 to 4000 cubic meters have been successfully filled with a variety of fill materials in the Netherlands, Germany, France, Japan, Brazil, Australia and the US. They have been used for submerged stability berms, groins, sill structures for controlling thalweg erosion, scour protection around piers, contraction dikes, dredge material containment and disposal of clean and contaminated materials. Dewatering applications for fine soil from navigation dredged material maintenance projects and sludge lagoons have been limited. Below is a list of existing and potential applications of this new and innovative technology.
