Title: Tent ground cloth?
Post by: mbattisti on July 08, 2017, 08:40:31 am
Anyone had any luck using tyvek house wrap as a waterproof ground cloth for a tent?  Worried about the long term durability of its weave.

Yes. Lasts long time. Crinkly.

Lasts forever, but you'll wake up the whole camp when you shake it out in the morning.

I've used heavy (6 mil) polyethylene sheet but Tyvek should work fine.  Why are you concerned about it's "long term" durability? It's cheap and easily replaced.

Remember to cut it just smaller than the floor, so it doesn't catch rain.

Related question: Is using a ground cloth better than just relying on a heavy waterproof floor?  That seems to work fine for me.

Yes, a good point.

Most tents don't have very heavy duty floors so the extra protection from abrasion is worthwhile.

Tyvek works fine and lasts very well.  That said I don't use a ground cloth any more.  I was happy to shed the extra weight.   I figure that if it comes to it I would patch or recoat the floor as needed, but in practice my tents typically fail somewhere other than the floor anyway.  That may be in part because I am only in the tent for sleeping and then only on the sleeping pad.  The lack of "traffic" directly on the floor keeps it pretty pristine.

I figure that worst case I'd enjoy the light weight of forgoing the ground cloth until the floor was in bad shape and start using a ground cloth then.  It has never come to that though as other things tend to fail before the floor on my tents.

BTW, on cutting the GC smaller than the floor...  When I did use one I cut it just a little larger and folded the excess under.  It worked fine.

A backpacking tent manufacturer said worn floors are rare.

I would not dream of pitching my BA Fly Creek UL 2 without something under it. My Seedhouse SL 2, which has a tougher floor, got a few holes in it after not all that much use.

I simply use one of those blue, plastic "tarps" you can find many places.

Having just upgraded to a 4# tent (2 person) from a same sized 6# 4 oz tent (ground cloths included) and seeing how thin the new fabric is I wouldn't think of going without a ground cloth. For years I used polyester window screen material (thanks Oris). No pooling of rain, pretty good protection.  This time I bought the ground cloth made for the tent.

Combined, I think I camped more than 300 days with my Hilleberg tent. There is still no hole and nothing to be patched.

My question is probably biased; i have only used inexpensive (Coleman) tents, which are heavy but sturdy.

If you camp in campgrounds, or other areas where the ground is generally smooth and free of debris, then a ground cloth is probably unnecessary. But if you sometimes camp on rocky ground or in areas where the ground may be covered with thorns, I would think a ground cloth would be useful.

I prefer to run sans underlayment. Less weight. With an inflated mattress, I don't miss it.

It is a matter of wear and tear (literally) on your tent floor, as well as some water getting through. Adds life to
 the tent.

Tyvek works great but there is more then one thickness. I have the "house warp" and it's holding up with no problems. Hint: to get rid of the noise and stiffness, toss it in the washing machine for a quick wash. Doesn't appear to lower the strength.
