I just made one from some of the tyvek roofing membrane, and was surprised to find it rather bulky when rolled up. 

 I'm slightly confused now that there might be different types of tyvek and I'd used the wrong one. 

What sort did you order?

House wrap that's the stuff I've seen sold and used as footprint material

I think there are multiple grades of Tyvek. There's a version for light chemical use that has a waterproof layer, as although the hdpe fibres in tyvek are waterproof, the various tyvek suits I've worn only seem to be showerproof at best.

Operating theatre drapes are tyvek, but again they have a waterproof (bloodproof?) side. They do make reasonable groundsheets (allegedly), but not sure about the longevity.

Let us know how the experiment goes!

I've made a ground sheet for tarping etc. It's good, but I tend to fold it and wonder if it leaks on the fold lines. I think it was house wrap I bought. Some chap on eBay selling it for backpacking.

Item number or link (please?)

It does leak eventually, at least the roofing grade does. I used some as temporary shed roof (over boards) and it started to leak after a few weeks. Must be UV damage or thermal expansion/contraction making the 'holes' bigger.

I didn't think links to ebay worked here.

I bought some bright yellow pvc from Pennine Outdoor years ago. OK its quite heavy, but it has proved indestructible over 20 odd years now!

bought some off ebay- from some bloke who sells it for this purpose in smallish bits.

 

Have used it perhaps 20 times- excellent.

I've been using tyvek for yonks, with my tarptents (they come with tyvek footprints as standard). Excellent stuff, highly recommended. I've yet to replace one. They get a bit muddy, but then I never bother to clean them so what can I expect. Over time (and especially when packing away in inclement weather), the nice folds you make will become very rounded, which makes putting it away slightly harder.

I've used Polycro as a footprint, and a groundsheet on its own when bikepacking under a tarp. So far, its surviving remarkably well, no holes at all after half a dozen uses, and I'm not gentle with gear. Stuffs into a small pocket and weighs nothing.

Dell on 07 Jul 2018
In reply to The Wild Scallion:

 Not sure what polycro is? A bit of googling suggests it's the same as DIY secondary glazing film!?

Yep, I made one for a recent trip - cheap, hard to puncture and very light. did tear a bit so be careful with the edges to avoid having obvious places a tear can start.

In reply to Dell:

Yes, polycro is secondary glazing film (made by 3M).

Ours has done about 60 nights on rocks, concrete, spiky grass etc. without tearing so far - it’s incredibly tough!

I wasn't aware of tyvek at the time but I made one for my Vango Helium a few years ago using a 'Military ipk kit' sheet. Its basically a kit issued to military personnel that allows them to dig a hole sheet it over and and then cover it in mud. Supposedly to protect them from radiation and they reckoned a tank could drive over the finished structure. It failed on both accounts but makes for a good light weight durable ground sheet.

I don't really understand the need for Tyvek but am willing to be educated, i just bought a large one of these and use it doubled for my footprints, works fine. i just fold it and slide it in the hydration sleeve of packs as its smaller than rolling.

Tyvek is much lighter than tarp! That all really.

That stuff i linked to is pretty light, i use it as a footprint for a TN Laser Comp on mountain marathons and light trips, also it's dirt cheap.
