Hi Ted, thanks very much for a reply, i was worried no-one would help
Unfortunately the supplier is an ordinary agricultural merchants an
doesn't know what the sheet is made of! They are trying to get hold o
the manufacturers but no luck so far. However I was told by a landscap
architect that silage sheet is good as long as its UV stable. What I'v
got is black in colour and quite thick, say about 0.7mm. Its not show
any signs of cracking while its been stored for the last 8 months.
spoke to another bloke that supplies various linings for slurry pit
and reservoirs and he said if its polypropelene it will be fine an
even if its PVC it will be okay especially if its covered over wit
another layer. I think the butyl pond lining manufacturers don't wan
people to know there are other options. What is EDPM? How much did i
cost and where did you get it?

I used EDPM from a place that manufactures it for usage aroun
chemical and
fuel tanks. I had no problems with it. Do you know what th
material you
are looking at is made of?

I would welcome any advice. I am building a pond for the firs
time, it
is a large pond approx 60 feet by 30 feet and about 6 feet deep i
the
middle. It has been excavated and now I aim to put a layer o
"Teram"
geotextile (bit like weedblock fabric) followed by about 1 inch o
sand
and then I aim to put down "silage sheet", this is the plasti
farmers
use to line silage and slurry pits and comes in very large sizes
It is
much cheaper than official pond liners. Then I intend to cover the
sheet with another layer of geotextile and then sand with patche
of
gravel for cosmetic effect. It will be trickle filled via a smal
pump
from a stream which comes off the mountains. Questions: anyon
else
used silage sheet? I'm pretty certain the sheet is UV stable bu
would
welcome comments and any advice?
