Any recommendations for a small ground sheet, up say 1 x 2 mtrs ?
I bought a survival bag for the purpose, but it’s got quite a few splits in now and with having two layers, they slide over each other meaning I’m sliding too. It’s also hard to get all the air out to roll back up to put in the rucsac after the activation.
The ultralight option is “polycryo” film. It is surprisingly durable, hikers have used the same sheet for an entire Appalachian Trail thru-hike. It absolutely will blow away in a wind, so keep hold of it. I’ve been using it for years and like it.
Duck Brand is one variety of this film. You can find it in hardware stores here in the US, but here is an Amazon UK link.
Here is the same stuff sold by an ultralight backpacking vendor.
Not quite a groundsheet, but I have been using a piece of aluminium bubble insulation as a sit mat with room for my butt and the rig. The same piece has lasted ages.
wow - never thought about. When activating in snow or rain I keep standing or wear waterproof trousers. For me working /p is something different than setting up a shack in the wilderness. As I’m getting older I have to rethink.

I intend to use it for the Portable Ops Challenge, so I can’t say how good it is yet, it’s certainly light. Up until now I have been using part of a heavy duty painters cover sheet.
I like the look of the car sunshade, it will also keep me off the ground and a bit warmer, I’ve seen those around and should roll up and be quite lightweight.
What ever I get I’ll post an update and how I get on with it.
You could also try the close foam cell stuff they use under floating wood floors. I got a big bit for nothing off our carpet fitters. It is about 2 or 3 mm thick and is the same stuff as sleeping/camping mats.
(this sounds a bit like the stuff G3CWI mentions in an earlier post).
If you know someone in the building trade, then you may be able to get hold of some Tyvek. It makes a very cheap groundsheet. Alternatively, you can buy some from Extremtextil:
It varies in price, which is why it’s handy if you know a builder who can let you have some at trade price. For camping, I made my own bathtub groundsheet with TPU coated ripstop nylon; very high spec:
Unfortunately Matthew I made a temporary bivvi bag out of that stuff. Mind did not work as a ground sheet - it might, and does make a water proof barrier in buildings but when subject to pressure - from your body weight it becomes water permeable.
I have a gardener’s kneeling mat as it was 95p and proper camping sit mats were many pounds. It’s been in use since 2006 and going strong still. Not very big especially compared with my backside but it is insulating and waterproof. I’ve avoided needing a groundsheet for 14years so far. However, if I did need one, a Tyvek sheet would be my choice and then I’d set the garden kneeler on that. The sheet would be waterproof enough for the weight, volume and cost.
