HDPE Positives And Negatives Of HDPE Liners For Slurry Storage Lagoon Lining

HDPE liner for lagoon, lake, pond and pool. As a result, you want to learn the good points and the bad aspects of using welded HDPE (plastic) liners for farm slurry storage lagoon lining.

All set? Let's start then. Primary the positions in favour along with the reasons supporting:

A very first point in support of HDPE liners for slurry storage lagoon lining will be they are cheap when compared with other lining materials, and when you consider how a great deal testing you need to do now on in-situ clay lining materials (in the UK nitrate vulnerable zones (NVZs)) and waiting for test results, before you can even start to build HDPE liner suppliers in Dubai.

The second point in favour could well be that there are plenty of installers who are used to lining landfills and ponds etc who will line a farm slurry storage lagoon quickly.
The third positive point is as they are thin there is not the same degree of excavation needed to remove and then place back in engineered compacted layers the necessary lining depth in clay which may be 1-metre thickness.

A 4th support point in favour will be that you, or your installation contractor, can check for integrity of the liner after installation quite easily using electrostatic "holiday" (spark) tests.

Last but not least, the 5th point is the Environment Agency will hopefully understand what this type of liner will do, know its low water permeability characteristics already, and hence acceptance of the design should be facilitated HDPE liner installation companies in UAE.

And on the other hand, to help keep this balanced, there are Cons; Against:

Firstly, the point against is going to be that this type of liner is easily damaged as it is so thin.
And the second negative point is if farm tractors etc run close to it the possibility of puncture leakage is more likely than in many other uses for HDPE lining membranes.

A third significant point against is although not particularly susceptible to ultra-violet degradation some does still occur, and many lined storage lagoon designs leave the HDPE exposed to the sunlight, reducing the life of the materials.

4th point in contra will be when a penetration does occur the potential for substantial volume leakage is greater than for a clay liner which may tend to self-repair itself.

5th and then finally, the last point in contra shall be that if rainwater gets behind an HDPE slurry storage liner over a period of time the liner may get pulled down off the banks around the slurry store, which again could cause leakage from the slurry storage.

So there you have it, the pros along with the cons, the points in favour and the points against HDPE liner Oman.

So, with the final analysis is HDPE liners for slurry storage lagoon lining the good thing? or just a bad thing?

The respond definitely seems to be "Yes" to both questions! HDPE liners for slurry storage lagoon lining is a blend of good and bad... It has to be left up to you, the reader to determine. The side, the good or the bad, has got the preponderance of weight of opinion?
