EPDM or HDPE
 

I dug a big hole (about 9000 square feet surface; 7 feet max. depth; bank at
4:1 slope) to make a waterfoul and wildlife pond. I have to use a liner. The
selection is between EPDM and HDPE.
which one is better?
do you have any link to suggest?

thanks a lot

Hi Peter:
That is a very large area for a liner and will be expensive. If it is
seven feet deep and the soil is compacted it should be able to retain
sufficent level as a wildlife pond, depending the rainfall in your
area or if there is a natural spring feed.
I have purchased liners - for much smaller ponds- from Anjon Building
Products, Chesterfield, MO. and found them very good to deal with. The
best of luck!!!

What is your plan for filtration? Is HDPE the stiffer, thinner stuff, also
called Permalon? (Off on tangent, where is Ken?)

I've only worked with EPDM, and from other posters here it seems easier to
work with as far as installing pipes and bottom drains. It is heavy though,
especially that much of it. ~ jan

I have used both and think they are both very good. The
EPDM will conform to the shape of the pond more easily, but
is very heavy. HDPE will fold and is lighter in weight and
much less expensive. I purchased my HDPE (Permalon) for
Kencofish.com and my EDPM is from Tetra - you can check out
their web sites.

Have you considered sodium bentonite? A natural lined pond is usually the
best choice for wildlife. Why do you say you have to use a liner?

I dug the hole years ago and compacted the soil, but when I fill it (water
from a well) the pond gets empty in a couple of days.

What do you mean with filtration?
Yes, HDPE is high density polyethylene (like Permalon)

I considered sodium bentonite, I' d like it, but it implies a lot of soil
moving and waterproofing is not 100% sure.



The main factors in the selection are duration and sturdiness ( maybe my
horse could decide to take a bath...)
anyway I plan to protect the bank with stones and gravel.

thanks to all

If you are close to these people they can save you money. They are the
cheapest I could find http://www.pondliner.com/

For that size, I really think you have to go with HDPE. EPDM is way too
heavy to work with at that size (it was as much as I could handle alone for
about 250sq ft. surface - about 1000 sq.ft. of actual EPDM).

For a size where you could use either, I wouldn't say either was really
better, just different.

I don't know what the difference is in the cost, but maybe you should look inito
using a geotextile fabric. My understanding is that they are much easier to lay
down in a large hole such as yours.

Bentonite will seal it as good as any natural pond and you can reshape,
dredge or use an excavator on it without draining it. I would suggest you
get a small piece of HDPE and put some gravel on it and have the horse walk
on it before you decide. Make sure it is rounded gravel and a foot thick.
