During construction deep trench walls will need support below the groundwater table to stop them from collapsing and making a freshly dug drain less than accessible. So to keep slurry and water diverted while a drain is being constructed, the use of a bio-polymer drain wall is exacted into place.

During construction deep trench walls will need support below the groundwater table to stop them from collapsing and making a freshly dug drain less than accessible. So to keep slurry and water diverted while a drain is being constructed, the use of a bio-polymer drain wall is exacted into place.
This method of drain construction can be seen at many locations alongside roads or new housing construction, where a French Drain construction is necessary.
Sheet steel or bentonite once the favored methods of holding back slurry and water, would need to be removed which is time consuming and also more costly, and has since become second to the bio-polymer drain.
Once the constructed drain has been backfilled the bio-polymer drain or slurry trench as it is also known, will degrade allowing the slurry return to the water and the drain is in effect born.
It is well documented that the use of bio-polymer drains can bring the cost of a project down 40% or more – a brilliant tool when estimating a project.
Is there any toxic elements released into the drain during the bio breakdown?
As the bio-polymer drain degrades naturally, it releases its own elements into the slurry; this process does not release any harmful chemicals or other toxic compounds into the water table.
As bio-polymer drains are so ecologically friendly, and involve less time during backfilling a drain, they have fast become a favored use as opposed to sheet steel and bentonite after the compound’s US introduction during the 1980’s.
What other uses can Bio-Polymer Drain walls be used for?
The construction industry has been methodical in the bio-polymer drain walls use – as the biopolymer wall is not just a one stop shop!
They have been used in building and construction techniques that involve:
- Collection of Leachate from Landfill Projects
- Earthen Dams (The Toe Drains)
- Pump and Treatment Systems where the collection of water is necessary.
- Manhole Construction.
- Deep Ground Excavations.
The uses for the bio-polymer drain walls are multi-purpose, if water needs to be held back and then allowed to flow back eventually, then these are the walls that a contract team should be venturing to use.
Are there any limitations to Bio-Polymer Drain Walls?
The main limitations would be depth, water pressure and speed of construction.
- Depth - Although bio-polymer walls have been used to depths of up to 80 feet, there may be a
limitation beyond that. Specialist bio-polymer advisories may need to be commissioned.
- Water Pressure – Construction must take into account any adverse water pressure, inclusive of weather events that could occur during the holding back of any water.
- Speed of Construction – As the bio-polymer is degradable, it become necessary to equate some quicker construction times than the standard sheet steel. So a workforce would need to be trained to have knowledge of this before a construction is attempted.
Conclusion
Bio-polymer drains are the ecological and project management solution to many construction projects. They are cost effective and much easier to manage than some of the techniques used in the past. Technology makes advances for a reason – bio-polymer is the answer to simplified below water table construction problems.
