Just wondered exactly how water resistant this stuff is when used as a groundsheet?
I'm trying to lighten my load a little, so Tyvek may be a good start.
TIA.

Who uses Tyvek (or a copy) as a groundsheet?

Not particularly waterproof, just water resistant IMO, I seem to remember a hydrostatic head of 1000mm for house wrap.
For this reason, I've just laminated a tyvek groundheet to some self adhesive carpet protector I use on site. Its not tested yet and it is quite heavy, I don't think it'll be the answer
Have you seen Polycryro? Its very strong and light plastic sheet. Wickes sell it as secondary glazing film. You'll be pushed to find anything lighter

Cheers bud, I knew it wasn't fully waterproof. Thanks for the heads up on the polycryo, I have to have a butchers and see if the dog punctures it!
Its got a very high tear strength but when its torn, it keeps going. Some Hippo tape or gaffer tape is a good partner to it to reinforce peg holes, or stick a rip back together
Iv been looking at this stuff for a ground sheet to Pete. Is sold In places like ridgeons too? We ain't got a wickes here in costa del march lol!!
Its a diy product mate, you might find it in a hardware shop locally or online. Ridgeons is trade, so I don't think you'll find it there.
I can grab some next time I'm in for ya, its not cheap though-think it was £7 or more. Its a big sheet though, enough for quite a few.

The cast iron stove and the canvas belltent might account for some of the weight...? Are you taking all 31 stoves with you?
Despite what other people say Spanders... I still think you're funny.
Besides; the frontier is only pressed steel not cast iron AND I'll have you know that on my last trip it was the Mini Bull stove and MyTi mug only...well I did take another Ti stove to experiment with as well!

If you're in a bivi bag, do you need a groundsheet at all, or are you taking a tent? I presume you're talking about the SDW?
Yes for the SDW. I could bivvy but my military bivi bags are nearly as heavy as my 2 man Luxe tepee, which is far more palatial!
I tried it a few years ago and its OK but will leak at points of pressure, such as where you knell or prop yourself up on an elbow.
So you can get polycryo at Wicks? That's a result as I bought a couple of pieces from an ultralight backpacking website a few years ago, my son took them on a trip and I never saw them again and I can't find anymore. Its really good stuff, very light, surprisingly strong and does the job as a groundsheet.
Does it have a brand name or anything like that or is it sold simply as polycryo sheets?

Its best known as roofing membrane or house wrap. I'm using it at work as waterproof dustsheets.
You can possibly get it free if there's a load thats been chucked in a skip on a new build development.
