will the tarp allow water to pass through

Most water passes through, but it will get heavy and you can see the wait of trapped water causing it to sag at times. My shade is 30x16' so the amount of trapped water (cohesion and adhesion properties of water to this mesh) does add up. But the water never pools, as the gaps are too large for that.

Yes it is porous material so the water will seep through if you water slowly. It also blocks the sun from drying out the ground so you will have to water less.

No, water does not get through the liner. At least I have never had this issue. The curtain will be wet when you touch it from either side, but it dries as it hangs there.

I agree with Michael that the cover will keep water from seeping through but do all you can to see that it won't puddle up in the first place.

No tarp needed. Full waterproof up to maybe 2-3 inches of water. But I doubt you'll ever be in that deep.

Yes....it is constructed as a large mesh .....water will definite flow through

Floor/cieling yes, through the roof not so sure. I used my through the exterior wall and it works fine. I suppose it should wofk through the roof as long as you seal out the water/weather good.

I haven't tested it, but due to the nature of the mechanism by which it locks to whatever you attach it to there is a small hole where water could probably get in. So probably not.

No, it is perforated and allows rain to come through. Also, after 6 months, high winds tore it to pieces.

I would say that IF you fabricate a cover or put a tarp over it with a bungee to hold closed, it should be fine.

It is a tightly woven solid material. Black on the underside green on top. The water accumulates on top and doesn't run through. It is like an outside tarp.

You can put a tarp or piece of plastic over it. You can also let water out and refill with warm water as needed

Yes but I'm not sure if eventually the material would get wet by soaking through. The inside is lined so it should be ok.

no is not never try it with water but i can tell there are gaps so water can go through.

It works better when you fold it back, although some of the water will still get through with the fabric on. During a slow, steady rain or when using an oscillating sprinkler most of the water seems to get through the fabric.

No the battery compartment isnt sealed so water could get in if directly exposed to rain. But I had mine attached under a tarp for 3 months and many hard rain storms with out any problems.

I have not personally used mine in the sand but I would say most definitely...yes it would come through. It is a mesh screen type fabric. The benefit of this is the water will go right through and it dries very fast. It is also heavy enough that it stays put in the wind. We love ours but, again, we don't use it in the sand! Hope this helps with your decision.
