Canvas I've found in our small town to 12K people has been fairly thick
and heavy. I've used some 8x10' sheets for equipment I leave outdoors;
however, there are time when I want to cover piles of good quality dirt
to prevent weeds from growing on it. I don't need heavy canvas for
that. I do have one 4x6' sheet with grommets in the corners that is
light. I'm not sure it's water proof, but that many not matter for my
application. Perhaps Amazon, Wall-Mart, Costco, Home Depot or other
big stores sell it. Ideas?
You are generally correct but Typar was designed for this purpose.
In googling, I did find a very similar product but reading reviews said
it did disintegrate in sun light. I definitely would not use any old
black plastic sheet.
How many decades are you planning on leaving this stuff? If you want
something that's going to last decades -- or even a couple of years -- in
direct contact with wet soils, then cotton canvas is NOT your answer. In
those cases, you want something non-organic, like a petroleum product. Like
Vapor barrier "plastic" (heavy LDPE) is pretty durable, even in sunlight.
You'll get several years out of it, at least.
Polypropylene tarps are almost as good, but they're "plastic" as well.
Farm-supply places (should be easy to find in your area, no?) sell weed-
control fabrics that are biodegradable. Problem is, they're also "plastic".
And they're biodegradable, which makes them just like cotton canvas.
Or is your objection to "plastic"...political...?
My objection to plastic used for tarps is they disintegrate easily and
spread their fiber in any wind, thereby making a mess.
As I said above, I have a 4x6' canvas (I think it's canvas. I have no
idea if it's cotton. It looks tougher.) that works fine. It's been
covering a pile of dirt for 3 years and shows no sign of wear.
We are facing three storms over the next five days. One is in progress
as I write. When it's over, I'll take that sheet to a h/w store and
ask them what it's made of.
BTW, I live in something of a rural area, and a fair number of
animals wander around--particularly deer. If a deer walks on a plastic
tarp, they often get punctured and start to shred in the wind.
Take a cigarette lighter to it (on a corner or hem). If it's a natural
fiber, it will scorch. If plastic, it will melt.
If it melts, smell the fumes. Do they smell like candle wax? Sulphur?
They may not be able to tell. A farm-supply place may be a better bet.
Point taken. Then you need a woven fiber of some kind. I have personally
found that what is most important is how well the sheet is secured. If
there's any sort of looseness, the wind will eventually make shreds of the
fabric. If the sheet is snug and tight and does not flap in the wind, it
will last a lot longer. Spikes and rocks help a lot.
I still don't think a natural fiber is what you need. Synthetics were
developed partially as an answer to natural fibers' shortcomings.
